2 Objects

The following subsections describe the objects that are passed between the clients and servers of the key management system. Some of these object types, called Base Objects, are used only in the protocol itself, and are not considered Managed Objects. Key management systems MAY choose to support a subset of the Managed Objects. The object descriptions refer to the primitive data types of which they are composed. These primitive data types are (see Section 9.1.1.4):

· Integer

· Long Integer

· Big Integer

· Enumeration – choices from a predefined list of values

· Boolean

· Text String – string of characters representing human-readable text

· Byte String – sequence of unencoded byte values

· Date-Time – date and time, with a granularity of one second

· Interval – a length of time expressed in seconds

Structures are composed of ordered lists of primitive data types or sub-structures.

2.1 Base Objects

These objects are used within the messages of the protocol, but are not objects managed by the key management system. They are components of Managed Objects.

2.1.1 Attribute

An Attribute object is a structure (see Table 2) used for sending and receiving Managed Object attributes. The Attribute Name is a text-string that is used to identify the attribute. The Attribute Index is an index number assigned by the key management server when a specified named attribute is allowed to have multiple instances. The Attribute Index is used to identify the particular instance. Attribute Indices SHALL start with 0. The Attribute Index of an attribute SHALL NOT change when other instances are added or deleted. For example, if a particular attribute has 4 instances with Attribute Indices 0, 1, 2 and 3, and the instance with Attribute Index 2 is deleted, then the Attribute Index of instance 3 is not changed. Attributes that have a single instance have an Attribute Index of 0, which is assumed if the Attribute Index is not specified. The Attribute Value is either a primitive data type or structured object, depending on the attribute.

Object	Encoding	REQUIRED
Attribute	Structure
Attribute Name	Text String	Yes
Attribute Index	Integer	No
Attribute Value	Varies, depending on attribute. See Section 3	Yes, except for the Notify operation (see Section 5.1)

Table 2: Attribute Object Structure

2.1.2 Credential

A Credential is a structure (see Table 3) used for client identification purposes and is not managed by the key management system (e.g., user id/password pairs, Kerberos tokens, etc). It MAY be used for authentication purposes as indicated in [KMIP-Prof].

Object	Encoding	REQUIRED

Username	Text String	Yes
Password	Text String	No

Table 4: Credential Value Structure for the Username and Password Credential

2.1.3 Key Block

A Key Block object is a structure (see Table 5) used to encapsulate all of the information that is closely associated with a cryptographic key. It contains a Key Value of one of the following Key Format Types:

· Raw – This is a key that contains only cryptographic key material, encoded as a string of bytes.

· Opaque – This is an encoded key for which the encoding is unknown to the key management system. It is encoded as a string of bytes.

· PKCS1 – This is an encoded private key, expressed as a DER-encoded ASN.1 PKCS#1 object.

· PKCS8 – This is an encoded private key, expressed as a DER-encoded ASN.1 PKCS#8 object, supporting both the RSAPrivateKey syntax and EncryptedPrivateKey.

· X.509 – This is an encoded object, expressed as a DER-encoded ASN.1 X.509 object.

· ECPrivateKey – This is an ASN.1 encoded elliptic curve private key.

· Several Transparent Key types – These are algorithm-specific structures containing defined values for the various key types, as defined in Section 2.1.7

· Extensions – These are vendor-specific extensions to allow for proprietary or legacy key formats.

The Key Block MAY contain the Key Compression Type, which indicates the format of the elliptic curve public key. By default, the public key is uncompressed.

The Key Block also has the Cryptographic Algorithm and the Cryptographic Length of the key contained in the Key Value field. Some example values are:

· RSA keys are typically 1024, 2048 or 3072 bits in length

· 3DES keys are typically from 112 to 192 bits (depending upon key length and the presence of parity bits)

· AES keys are 128, 192 or 256 bits in length

The Key Block SHALL contain a Key Wrapping Data structure if the key in the Key Value field is wrapped (i.e., encrypted, or MACed/signed, or both).

Key Wrapping Data	Structure, see 2.1.5	No, SHALL only be present if the key is wrapped.

Table 5: Key Block Object Structure

2.1.4 Key Value

The Key Value is used only inside a Key Block and is either a Byte String or a structure (see Table 6):

· The Key Value structure contains the key material, either as a byte string or as a Transparent Key structure (see Section 2.1.7), and OPTIONAL attribute information that is associated and encapsulated with the key material. This attribute information differs from the attributes associated with Managed Objects, and which is obtained via the Get Attributes operation, only by the fact that it is encapsulated with (and possibly wrapped with) the key material itself.

· The Key Value Byte String is the wrapped TTLV-encoded (see Section 9.1) Key Value structure.

Object	Encoding	REQUIRED
Key Value	Structure
Key Material	Byte String: for Raw, Opaque, PKCS1, PKCS8, ECPrivateKey, or Extension Key Format types; Structure: for Transparent, or Extension Key Format Types	Yes

Table 6: Key Value Object Structure

2.1.5 Key Wrapping Data

The Key Block MAY also supply OPTIONAL information about a cryptographic key wrapping mechanism used to wrap the Key Value. This consists of a Key Wrapping Data structure (see Table 7). It is only used inside a Key Block.

This structure contains fields for:

· A Wrapping Method, which indicates the method used to wrap the Key Value.

· Encryption Key Information, which contains the Unique Identifier (see 3.1) value of the encryption key and associated cryptographic parameters.

· MAC/Signature Key Information, which contains the Unique Identifier value of the MAC/signature key and associated cryptographic parameters.

· A MAC/Signature, which contains a MAC or signature of the Key Value.

· An IV/Counter/Nonce, if REQUIRED by the wrapping method.

If wrapping is used, then the whole Key Value structure is wrapped unless otherwise specified by the Wrapping Method. The algorithms used for wrapping are given by the Cryptographic Algorithm attributes of the encryption key and/or MAC/signature key; the block-cipher mode, padding method, and hashing algorithm used for wrapping are given by the Cryptographic Parameters in the Encryption Key Information and/or MAC/Signature Key Information, or, if not present, from the Cryptographic Parameters attribute of the respective key(s). At least one of the Encryption Key Information and the MAC/Signature Key Information SHALL be specified.

The following wrapping methods are currently defined:

· Encrypt only (i.e., encryption using a symmetric key or public key, or authenticated encryption algorithms that use a single key)

· MAC/sign only (i.e., either MACing the Key Value with a symmetric key, or signing the Key Value with a private key)

· Encrypt then MAC/sign

· MAC/sign then encrypt

· TR-31

· Extensions

Table 9: MAC/Signature Key Information Object Structure

2.1.6 Key Wrapping Specification

This is a separate structure (see Table 10) that is defined for operations that provide the option to return wrapped keys. The Key Wrapping Specification SHALL be included inside the operation request if clients request the server to return a wrapped key. If Cryptographic Parameters are specified in the Encryption Key Information and/or the MAC/Signature Key Information of the Key Wrapping Specification, then the server SHALL verify that they match one of the instances of the Cryptographic Parameters attribute of the corresponding key. If Cryptographic Parameters are omitted, then the server SHALL use the Cryptographic Parameters attribute with the lowest Attribute Index of the corresponding key. If the corresponding key does not have any Cryptographic Parameters attribute, or if no match is found, then an error is returned.

This structure contains:

· A Wrapping Method that indicates the method used to wrap the Key Value.

· Encryption Key Information with the Unique Identifier value of the encryption key and associated cryptographic parameters.

· MAC/Signature Key Information with the Unique Identifier value of the MAC/signature key and associated cryptographic parameters.

· Zero or more Attribute Names to indicate the attributes to be wrapped with the key material.

2.2 Managed Objects

Managed Objects are objects that are the subjects of key management operations, which are described in Sections 4 and 5. Managed Cryptographic Objects are the subset of Managed Objects that contain cryptographic material (e.g. certificates, keys, and secret data).

2.2.1 Certificate

A Managed Cryptographic Object that is a digital certificate. For X.509 certificates, its is a DER-encoded X.509 public key certificate, For PGP certificates, it is a transferable public key in the OpenPGP message format..

2.2.5 Split Key

A Managed Cryptographic Object that is a Split Key. A split key is a secret, usually a symmetric key or a private key that has been split into a number of parts, each of which MAY then be distributed to several key holders, for additional security. The Split Key Parts field indicates the total number of parts, and the Split Key Threshold field indicates the minimum number of parts needed to reconstruct the entire key. The Key Part Identifier indicates which key part is contained in the cryptographic object, and SHALL be at least 1 and SHALL be less than or equal to Split Key Parts.

Key Block	Structure, see 2.1.3	Yes

Table 30: Split Key Object Structure

There are three Split Key Methods for secret sharing: the first one is based on XOR, and the other two are based on polynomial secret sharing, according to [SHAMIR1979].

Let L be the minimum number of bits needed to represent all values of the secret.

· When the Split Key Method is XOR, then the Key Material in the Key Value of the Key Block is of length L bits. The number of split keys is Split Key Parts (identical to Split Key Threshold), and the secret is reconstructed by XORing all of the parts.

· When the Split Key Method is Polynomial Sharing Prime Field, then secret sharing is performed in the field GF(Prime Field Size), represented as integers, where Prime Field Size is a prime bigger than 2^L.

· When the Split Key Method is Polynomial Sharing GF(2¹⁶), then secret sharing is performed in the field GF(2¹⁶). The Key Material in the Key Value of the Key Block is a bit string of length L, and when L is bigger than 2¹⁶, then secret sharing is applied piecewise in pieces of 16 bits each. The Key Material in the Key Value of the Key Block is the concatenation of the corresponding shares of all pieces of the secret.

Secret sharing is performed in the field GF(2¹⁶), which is represented as an algebraic extension of GF(2⁸):

GF(2¹⁶) ≈ GF(2⁸) [y]/(y²+y+m), where m is defined later.

An element of this field then consists of a linear combination uy + v, where u and v are elements of the smaller field GF(2⁸).

The representation of field elements and the notation in this section rely on [FIPS197], Sections 3 and 4. The field GF(2⁸) is as described in [FIPS197],

GF(2⁸) ≈ GF(2) [x]/(x⁸+x⁴+x³+x+1).

An element of GF(2⁸) is represented as a byte. Addition and subtraction in GF(2⁸) is performed as a bit-wise XOR of the bytes. Multiplication and inversion are more complex (see [FIPS197] Section 4.1 and 4.2 for details).

An element of GF(2¹⁶) is represented as a pair of bytes (u, v). The element m is given by

m = x⁵+x⁴+x³+x,

which is represented by the byte 0x3A (or {3A} in notation according to [FIPS197]).

Addition and subtraction in GF(2¹⁶) both correspond to simply XORing the bytes. The product of two elements ry + s and uy + v is given by

(ry + s) (uy + v) = ((r + s)(u + v) + sv)y + (ru + svm).

The inverse of an element uy + v is given by

(uy + v)^-1 = ud^-1y + (u + v)d^-1, where d = (u + v)v + mu².

2.2.6 Template

A Template is a named Managed Object containing the client-settable attributes of a Managed Cryptographic Object (i.e., a stored, named list of attributes). A Template is used to specify the attributes of a new Managed Cryptographic Object in various operations. It is intended to be used to specify the cryptographic attributes of new objects in a standardized or convenient way. None of the client-settable attributes specified in a Template except the Name attribute apply to the template object itself, but instead apply to any object created using the Template.

The Template MAY be the subject of the Register, Locate, Get, Get Attributes, Get Attribute List, Add Attribute, Modify Attribute, Delete Attribute, and Destroy operations.

An attribute specified in a Template is applicable either to the Template itself or to objects created using the Template.

Attributes applicable to the Template itself are: Unique Identifier, Object Type, Name, Initial Date, Archive Date, and Last Change Date.

Attributes applicable to objects created using the Template are:

· Cryptographic Algorithm

· Cryptographic Length

· Cryptographic Domain Parameters

· Cryptographic Parameters

· Operation Policy Name

· Cryptographic Usage Mask

· Usage Limits

· Activation Date

· Process Start Date

· Protect Stop Date

· Deactivation Date

· Object Group

· Application Specific Information

· Contact Information

3 Attributes

The following subsections describe the attributes that are associated with Managed Objects. Attributes that an object MAY have multiple instances of are referred to as multi-instance attributes. All instances of an attribute SHOULD have a different value. Similarly, attributes which an object MAY only have at most one instance of are referred to as single-instance attributes. These attributes are able to be obtained by a client from the server using the Get Attribute operation. Some attributes are able to be set by the Add Attribute operation or updated by the Modify Attribute operation, and some are able to be deleted by the Delete Attribute operation if they no longer apply to the Managed Object. Read-only attributes are attributes that SHALL NOT be modified by either server or client, and that SHALL NOT be deleted by a client.

When attributes are returned by the server (e.g., via a Get Attributes operation), the attribute value returned MAY differ for different clients (e.g., the Cryptographic Usage Mask value MAY be different for different clients, depending on the policy of the server).

The first table in each subsection contains the attribute name in the first row. This name is the canonical name used when managing attributes using the Get Attributes, Get Attribute List, Add Attribute, Modify Attribute, and Delete Attribute operations.

A server SHALL NOT delete attributes without receiving a request from a client until the object is destroyed. After an object is destroyed, the server MAY retain all, some or none of the object attributes, depending on the object type and server policy.

The second table in each subsection lists certain attribute characteristics (e.g., “SHALL always have a value”): Table 34 below explains the meaning of each characteristic that may appear in those tables. The server policy MAY further restrict these attribute characteristics.

SHALL always have a value	All Managed Objects that are of the Object Types for which this attribute applies, SHALL always have this attribute set once the object has been created or registered, up until the object has been destroyed.
Initially set by	Who is permitted to initially set the value of the attribute (if the attribute has never been set, or if all the attribute values have been deleted)?
Modifiable by server	Is the server allowed to change an existing value of the attribute without receiving a request from a client?
Modifiable by client	Is the client able to change an existing value of the attribute value once it has been set?
Deletable by client	Is the client able to delete an instance of the attribute?
Multiple instances permitted	Are multiple instances of the attribute permitted?
When implicitly set	Which operations MAY cause this attribute to be set even if the attribute is not specified in the operation request itself?
Applies to Object Types	Which Managed Objects MAY have this attribute set?

Table 34: Attribute Rules

3.1 Unique Identifier

The Unique Identifier is generated by the key management system to uniquely identify a Managed Object. It is only REQUIRED to be unique within the identifier space managed by a single key management system, however it is RECOMMENDED that this identifier be globally unique in order to allow for a key management domain export of such objects. This attribute SHALL be assigned by the key management system at creation or registration time, and then SHALL NOT be changed or deleted before the object is destroyed.

The Name attribute is a structure (see Table 37) used to identify and locate the object. This attribute is assigned by the client, and the Name Value is intended to be in a form that humans are able to interpret. The key management system MAY specify rules by which the client creates valid names. Clients are informed of such rules by a mechanism that is not specified by this standard. Names SHALL be unique within a given key management domain, but are not REQUIRED to be globally unique.

3.9 Certificate Identifier

The Certificate Identifier attribute is a structure (see Table 52) used to provide the identification of a certificate. For X.509 certificates, it contains the Issuer Distinguished Name (i.e., from the Issuer field of the certificate) and the Certificate Serial Number (i.e., from the Serial Number field of the certificate). For PGP certificates, the Issuer contains the OpenPGP Key ID of the key issuing the signature (the signature that represents the certificate). The Certificate Identifier SHALL be set by the server when the certificate is created or registered and then SHALL NOT be changed or deleted before the object is destroyed.

Object	Encoding	REQUIRED

Table 53: Certificate Identifier Attribute Rules

3.10 Certificate Subject

The Certificate Subject attribute is a structure (see Table 54) used to identify the subject of a certificate. For X.509 certificates, it contains the Subject Distinguished Name (i.e., from the Subject field of the certificate). It MAY include one or more alternative names (e.g., email address, IP address, DNS name) for the subject of the certificate (i.e., from the Subject Alternative Name extension within the certificate). For PGP certificates, the Certificate Subject Distinguished Name contains the content of the first User ID packet in the PGP certificate (that is, the first User ID packet after the Public-Key packet in the transferable public key that forms the PGP certificate). These values SHALL be set by the server based on the information it extracts from the certificate that is created (as a result of a Certify or a Re-certify operation) or registered (as part of a Register operation) and SHALL NOT be changed or deleted before the object is destroyed.

If the Subject Alternative Name extension is included in the certificate and is marked CRITICAL (i.e., within the certificate itself), then it is possible to issue an X.509 certificate where the subject field is left blank. Therefore an empty string is an acceptable value for the Certificate Subject Distinguished Name.

3.11 Certificate Issuer

The Certificate Issuer attribute is a structure (see Table 57) used to identify the issuer of a certificate, containing the Issuer Distinguished Name (i.e., from the Issuer field of the certificate). It MAY include one or more alternative names (e.g., email address, IP address, DNS name) for the issuer of the certificate (i.e., from the Issuer Alternative Name extension within the certificate). The server SHALL set these values based on the information it extracts from a certificate that is created as a result of a Certify or a Re-certify operation or is sent as part of a Register operation. These values SHALL NOT be changed or deleted before the object is destroyed.

3.12 Digest

The Digest attribute is a structure (see Table 58) that contains the digest value of the key or secret data (i.e., digest of the Key Material), certificate (i.e., digest of the Certificate Value), or opaque object (i.e., digest of the Opaque Data Value). Multiple digests MAY be calculated using different algorithms. If an instance of this attribute exists, then it SHALL be computed with the SHA-256 hashing algorithm; the server MAY store additional digests using the algorithms listed in Section 9.1.3.2.15. The digest(s) are static and SHALL be set by the server when the object is created or registered, provided that the server has access to the Key Material or the Digest Value (possibly obtained via out-of-band mechanisms).

3.13 Operation Policy Name

An operation policy controls what entities MAY perform which key management operations on the object. The content of the Operation Policy Name attribute is the name of a policy object known to the key management system and, therefore, is server dependent. The named policy objects are created and managed using mechanisms outside the scope of the protocol. The policies determine what entities MAY perform specified operations on the object, and which of the object’s attributes MAY be modified or deleted. The Operation Policy Name attribute SHOULD be set when operations that result in a new Managed Object on the server are executed. It is set either explicitly or via some default set by the server, which then applies the named policy to all subsequent operations on the object.

Table 61: Operation Policy Name Attribute Rules

3.13.1 Operations outside of operation policy control

Some of the operations SHOULD be allowed for any client at any time, without respect to operation policy. These operations are:

· Create

· Create Key Pair

· Register

· Certify

· Re-certify

· Validate

· Query

· Cancel

· Poll

3.13.2 Default Operation Policy

A key management system implementation SHALL implement at least one named operation policy, which is used for objects when the Operation Policy attribute is not specified by the Client in operations that result in a new Managed Object on the server, or in a template specified in these operations. This policy is named default. It specifies the following rules for operations on objects created or registered with this policy, depending on the object type. For the profiles defined in [KMIP-Prof], the creator SHALL be as defined in [KMIP-Prof].

3.13.2.1 Default Operation Policy for Secret Objects

This policy applies to Symmetric Keys, Private Keys, Split Keys, Secret Data, and Opaque Objects.

Table 63: Default Operation Policy for Certificates and Public Key Objects

3.13.2.3 Default Operation Policy for Template Objects

The operation policy specified as an attribute in the Register operation for a template object is the operation policy used for objects created using that template, and is not the policy used to control operations on the template itself. There is no mechanism to specify a policy used to control operations on template objects, so the default policy for template objects is always used for templates created by clients using the Register operation to create template objects.

Default Operation Policy for Private Template Objects

3.14 Cryptographic Usage Mask

The Cryptographic Usage Mask defines the cryptographic usage of a key. This is a bit mask that indicates to the client which cryptographic functions MAY be performed using the key, and which ones SHALL NOT be performed.

· Sign

· Verify

· Encrypt

· Decrypt

· Wrap Key

· Unwrap Key

· Export

· MAC Generate

· MAC Verify

· Derive Key

· Content Commitment

· Key Agreement

· Certificate Sign

· CRL Sign

· Generate Cryptogram

· Validate Cryptogram

· Translate Encrypt

· Translate Decrypt

· Translate Wrap

· Translate Unwrap

This list takes into consideration values that MAY appear in the Key Usage extension in an X.509 certificate. However, the list does not consider the additional usages that MAY appear in the Extended Key Usage extension.

X.509 Key Usage values SHALL be mapped to Cryptographic Usage Mask values in the following manner:

X.509 Key Usage to Cryptographic Usage Mask Mapping
X.509 Key Usage Value	Cryptographic Usage Mask Value

3.15 Lease Time

The Lease Time attribute defines a time interval for a Managed Cryptographic Object beyond which the client SHALL NOT use the object without obtaining another lease. This attribute always holds the initial length of time allowed for a lease, and not the actual remaining time. Once its lease expires, the client is only able to renew the lease by calling Obtain Lease. A server SHALL store in this attribute the maximum Lease Time it is able to serve and a client obtains the lease time (with Obtain Lease) that is less than or equal to the maximum Lease Time. This attribute is read-only for clients. It SHALL be modified by the server only.

3.16 Usage Limits

The Usage Limits attribute is a mechanism for limiting the usage of a Managed Cryptographic Object. It only applies to Managed Cryptographic Objects that are able to be used for applying cryptographic protection and it SHALL only reflect their usage for applying that protection (e.g., encryption, signing, etc.). This attribute does not necessarily exist for all Managed Cryptographic Objects, since some objects are able to be used without limit for cryptographically protecting data, depending on client/server policies. Usage for processing cryptographically-protected data (e.g., decryption, verification, etc.) is not limited. The Usage Limits attribute has the three following fields:

· Usage Limits Total – the total number of Usage Limits Units allowed to be protected. This is the total value for the entire life of the object and SHALL NOT be changed once the object begins to be used for applying cryptographic protection.

· Usage Limits Count – the currently remaining number of Usage Limits Units allowed to be protected by the object.

· Usage Limits Unit – The type of quantity for which this structure specifies a usage limit (e.g., byte, object).

When the attribute is initially set (usually during object creation or registration), the Usage Limits Count is set to the Usage Limits Total value allowed for the useful life of the object, and are decremented when the object is used. The server SHALL ignore the Usage Limits Count value if the attribute is specified in an operation that creates a new object. Changes made via the Modify Attribute operation reflect corrections to the Usage Limits Total value, but they SHALL NOT be changed once the Usage Limits Count value has changed by a Get Usage Allocation operation. The Usage Limits Count value SHALL NOT be set or modified by the client via the Add Attribute or Modify Attribute operations.

3.17 State

This attribute is an indication of the State of an object as known to the key management server. The State SHALL NOT be changed by using the Modify Attribute operation on this attribute. The state SHALL only be changed by the server as a part of other operations or other server processes. An object SHALL be in one of the following states at any given time. (Note: These states correspond to those described in [SP800-57-1]).

Figure 1: Cryptographic Object States and Transitions

· Pre-Active: The object exists but is not yet usable for any cryptographic purpose.

· Active: The object MAY be used for all cryptographic purposes that are allowed by its Cryptographic Usage Mask attribute and, if applicable, by its Process Start Date (see 3.20) and Protect Stop Date (see 3.21) attributes.

· Deactivated: The object SHALL NOT be used for applying cryptographic protection (e.g., encryption or signing), but, if permitted by the Cryptographic Usage Mask attribute, then the object MAY be used to process cryptographically-protected information (e.g., decryption or verification), but only under extraordinary circumstances and when special permission is granted.

· Compromised: It is possible that the object has been compromised, and SHOULD only be used to process cryptographically-protected information in a client that is trusted to use managed objects that have been compromised.

· Destroyed: The object is no longer usable for any purpose.

· Destroyed Compromised: The object is no longer usable for any purpose; however its compromised status MAY be retained for audit or security purposes.

State transitions occur as follows:

1. The transition from a non-existent key to the Pre-Active state is caused by the creation of the object. When an object is created or registered, it automatically goes from non-existent to Pre-Active. If, however, the operation that creates or registers the object contains an Activation Date that has already occurred, then the state immediately transitions from Pre-Active to Active. In this case, the server SHALL set the Activation Date attribute to the time when the operation is received, or fail the request attempting to create or register the object, depending on server policy. If the operation contains an Activation Date attribute that is in the future, or contains no Activation Date, then the Cryptographic Object is initialized in the key management system in the Pre-Active state.

2. The transition from Pre-Active to Destroyed is caused by a client issuing a Destroy operation. The server destroys the object when (and if) server policy dictates.

3. The transition from Pre-Active to Compromised is caused by a client issuing a Revoke operation with a Revocation Reason of Compromised.

4. The transition from Pre-Active to Active SHALL occur in one of three ways:

· The Activation Date is reached.

· A client successfully issues a Modify Attribute operation, modifying the Activation Date to a date in the past, or the current date.

· A client issues an Activate operation on the object. The server SHALL set the Activation Date to the time the Activate operation is received.

5. The transition from Active to Compromised is caused by a client issuing a Revoke operation with a Revocation Reason of Compromised.

6. The transition from Active to Deactivated SHALL occur in one of three ways:

· The object's Deactivation Date is reached.

· A client issues a Revoke operation, with a Revocation Reason other than Compromised.

· The client successfully issues a Modify Attribute operation, modifying the Deactivation Date to a date in the past, or the current date.

7. The transition from Deactivated to Destroyed is caused by a client issuing a Destroy operation, or by a server, both in accordance with server policy. The server destroys the object when (and if) server policy dictates.

8. The transition from Deactivated to Compromised is caused by a client issuing a Revoke operation with a Revocation Reason of Compromised.

9. The transition from Compromised to Destroyed Compromised is caused by a client issuing a Destroy operation, or by a server, both in accordance with server policy. The server destroys the object when (and if) server policy dictates.

10. The transition from Destroyed to Destroyed Compromised is caused by a client issuing a Revoke operation with a Revocation Reason of Compromised.

Only the transitions described above are permitted.

Table 96: Object Group Attribute Rules

3.29 Link

The Link attribute is a structure (see Table 97) used to create a link from one Managed Cryptographic Object to another, closely related target Managed Cryptographic Object. The link has a type, and the allowed types differ, depending on the Object Type of the Managed Cryptographic Object, as listed below. The Linked Object Identifier identifies the target Managed Cryptographic Object by its Unique Identifier. The link contains information about the association between the Managed Cryptographic Objects (e.g., the private key corresponding to a public key; the parent certificate for a certificate in a chain; or for a derived symmetric key, the base key from which it was derived).

Possible values of Link Type in accordance with the Object Type of the Managed Cryptographic Object are:

· Private Key Link. For a Public Key object: the private key corresponding to the public key.

· Public Key Link. For a Private Key object: the public key corresponding to the private key. For a Certificate object: the public key contained in the certificate.

· Certificate Link. For Certificate objects: the parent certificate for a certificate in a certificate chain. For Public Key objects: the corresponding certificate(s), containing the same public key.

· Derivation Base Object Link for a derived Symmetric Key object: the object(s) from which the current symmetric key was derived.

· Derived Key Link: the symmetric key(s) that were derived from the current object.

· Replacement Object Link. For a Symmetric Key object: the key that resulted from the re-key of the current key. For a Certificate object: the certificate that resulted from the re-certify. Note that there SHALL be only one such replacement object per Managed Object.

· Replaced Object Link. For a Symmetric Key object: the key that was re-keyed to obtain the current key. For a Certificate object: the certificate that was re-certified to obtain the current certificate.

The Link attribute SHOULD be present for private keys and public keys for which a certificate chain is stored by the server, and for certificates in a certificate chain.

Note that it is possible for a Managed Object to have multiple instances of the Link attribute (e.g., a Private Key has links to the associated certificate, as well as the associated public key; a Certificate object has links to both the public key and to the certificate of the certification authority (CA) that signed the certificate).

It is also possible that a Managed Object does not have links to associated cryptographic objects. This MAY occur in cases where the associated key material is not available to the server or client (e.g., the registration of a CA Signer certificate with a server, where the corresponding private key is held in a different manner).

3.30 Application Specific Information

The Application Specific Information attribute is a structure (see Table 99) used to store data specific to the application(s) using the Managed Object. It consists of the following fields: an Application Namespace and Application Data specific to that application namespace.

Clients MAY request to set (i.e., using any of the operations that result in new Managed Object(s) on the server or adding/modifying the attribute of an existing Managed Object) an instance of this attribute with a particular Application Namespace while omitting Application Data. In that case, if the server supports this namespace (as indicated by the Query operation in Section 4.24), then it SHALL return a suitable Application Data value. If the server does not support this namespace, then an error SHALL be returned.

3.33 Custom Attribute

A Custom Attribute is a client- or server-defined attribute intended for vendor-specific purposes. It is created by the client and not interpreted by the server, or is created by the server and MAY be interpreted by the client. All custom attributes created by the client SHALL adhere to a naming scheme, where the name of the attribute SHALL have a prefix of 'x-'. All custom attributes created by the key management server SHALL adhere to a naming scheme where the name of the attribute SHALL have a prefix of 'y-'. The server SHALL NOT accept a client-created or modified attribute, where the name of the attribute has a prefix of ‘y-‘. The tag type Custom Attribute is not able to identify the particular attribute; hence such an attribute SHALL only appear in an Attribute Structure with its name as defined in Section 2.1.1.

4 Client-to-Server Operations

The following subsections describe the operations that MAY be requested by a key management client. Not all clients have to be capable of issuing all operation requests; however any client that issues a specific request SHALL be capable of understanding the response to the request. All Object Management operations are issued in requests from clients to servers, and results obtained in responses from servers to clients. Multiple operations MAY be combined within a batch, resulting in a single request/response message pair.

A number of the operations whose descriptions follow are affected by a mechanism referred to as the ID Placeholder.

The key management server SHALL implement a temporary variable called the ID Placeholder. This value consists of a single Unique Identifier. It is a variable stored inside the server that is only valid and preserved during the execution of a batch of operations. Once the batch of operations has been completed, the ID Placeholder value SHALL be discarded and/or invalidated by the server, so that subsequent requests do not find this previous ID Placeholder available.

The ID Placeholder is obtained from the Unique Identifier returned in response to the Create, Create Pair, Register, Derive Key, Re-Key, Certify, Re-Certify, Locate, and Recover operations. If any of these operations successfully completes and returns a Unique Identifier, then the server SHALL copy this Unique Identifier into the ID Placeholder variable, where it is held until the completion of the operations remaining in the batched request or until a subsequent operation in the batch causes the ID Placeholder to be replaced. If the Batch Error Continuation Option is set to Stop and the Batch Order Option is set to true, then subsequent operations in the batched request MAY make use of the ID Placeholder by omitting the Unique Identifier field from the request payloads for these operations.

Requests MAY contain attribute values to be assigned to the object. This information is specified with a Template-Attribute (see Section 2.1.8) that contains zero or more template names and zero or more individual attributes. If more than one template name is specified, and there is a conflict between the single-instance attributes in the templates, then the value in the last of the conflicting templates takes precedence. If there is a conflict between the single-instance attributes in the request and the single-instance attributes in a specified template, then the attribute values in the request take precedence. For multi-value attributes, the union of attribute values is used when the attributes are specified more than once.

Responses MAY contain attribute values that were not specified in the request, but have been implicitly set by the server. This information is specified with a Template-Attribute that contains one or more individual attributes.

For any operations that operate on Managed Objects already stored on the server, any archived object SHALL first be made available by a Recover operation (see Section 4.22) before they MAY be specified (i.e., as on-line objects).

4.1 Create

This operation requests the server to generate a new symmetric key as a Managed Cryptographic Object. This operation is not used to create a Template object (see Register operation, Section 4.3).

The request contains information about the type of object being created, and some of the attributes to be assigned to the object (e.g., Cryptographic Algorithm, Cryptographic Length, etc). This information MAY be specified by the names of Template objects that already exist.

The response contains the Unique Identifier of the created object. The server SHALL copy the Unique Identifier returned by this operation into the ID Placeholder variable.

Request Payload
Object	REQUIRED	Description
Object Type, see 3.3	Yes	Determines the type of object to be created.
Template-Attribute, see 2.1.8	Yes	Specifies desired object attributes using templates and/or individual attributes.

Cryptographic Algorithm, see 3.4	Yes
Cryptographic Usage Mask, see 3.14	Yes

Table 109: Create Attribute Requirements

4.2 Create Key Pair

This operation requests the server to generate a new public/private key pair and register the two corresponding new Managed Cryptographic Objects.

The request contains attributes to be assigned to the objects (e.g., Cryptographic Algorithm, Cryptographic Length, etc). Attributes and Template Names MAY be specified for both keys at the same time by specifying a Common Template-Attribute object in the request. Attributes not common to both keys (e.g., Name, Cryptographic Usage Mask) MAY be specified using the Private Key Template-Attribute and Public Key Template-Attribute objects in the request, which take precedence over the Common Template-Attribute object.

A Link Attribute is automatically created by the server for each object, pointing to the corresponding object. The response contains the Unique Identifiers of both created objects. The ID Placeholder value SHALL be set to the Unique Identifier of the Private Key.

Request Payload
Object	REQUIRED	Description
Common Template-Attribute, see 2.1.8	No	Specifies desired attributes in templates and/or as individual attributes that apply to both the Private and Public Key Objects.
Private Key Template-Attribute, see 2.1.8	No	Specifies templates and/or attributes that apply to the Private Key Object. Order of precedence applies.
Public Key Template-Attribute, see 2.1.8	No	Specifies templates and/or attributes that apply to the Public Key Object. Order of precedence applies.

Table 110: Create Key Pair Request Payload

For multi-instance attributes, the union of the values found in the templates and attributes of the Common, Private, and Public Key Template-Attribute is used. For single-instance attributes, the order of precedence is as follows:

1. attributes specified explicitly in the Private and Public Key Template-Attribute, then

2. attributes specified via templates in the Private and Public Key Template-Attribute, then

3. attributes specified explicitly in the Common Template-Attribute, then

4. attributes specified via templates in the Common Template-Attribute

If there are multiple templates in the Common, Private, or Public Key Template-Attribute, then the last value of the single-instance attribute that conflicts takes precedence.

Response Payload
Object	REQUIRED	Description
Private Key Unique Identifier, see 3.1	Yes	The Unique Identifier of the newly created Private Key object.
Public Key Unique Identifier, see 3.1	Yes	The Unique Identifier of the newly created Public Key object.
Private Key Template-Attribute, see 2.1.8	No	An OPTIONAL list of attributes, for the Private Key Object, with values that were not specified in the request, but have been implicitly set by the key management server.
Public Key Template-Attribute, see 2.1.8	No	An OPTIONAL list of attributes, for the Public Key Object, with values that were not specified in the request, but have been implicitly set by the key management server.

Table 111: Create Key Pair Response Payload

Table 112 indicates which attributes SHALL be included in the Create Key pair request using Template-Attribute objects, as well as which attributes SHALL have the same value for the Private and Public Key.

Attribute	REQUIRED	SHALL contain the same value for both Private and Public Key
Cryptographic Algorithm, see 3.4	Yes	Yes
Cryptographic Length, see 3.5	No	Yes
Cryptographic Usage Mask, see 3.14	Yes	No
Cryptographic Domain Parameters, see 3.7	No	Yes
Cryptographic Parameters, see 3.6	No	Yes

Table 112: Create Key Pair Attribute Requirements

Setting the same Cryptographic Length value for both private and public key does not imply that both keys are of equal length. For RSA, Cryptographic Length corresponds to the bit length of the Modulus. For DSA and DH algorithms, Cryptographic Length corresponds to the bit length of parameter P, and the bit length of Q is set separately in the Cryptographic Domain Parameters attribute. For ECDSA, ECDH, and ECMQV algorithms, Cryptographic Length corresponds to the bit length of parameter Q.

4.3 Register

This operation requests the server to register a Managed Object that was created by the client or obtained by the client through some other means, allowing the server to manage the object. The arguments in the request are similar to those in the Create operation, but also MAY contain the object itself for storage by the server. Optionally, objects that are not to be stored by the key management system MAY be omitted from the request (e.g., private keys).

The request contains information about the type of object being registered and some of the attributes to be assigned to the object (e.g., Cryptographic Algorithm, Cryptographic Length, etc). This information MAY be specified by the use of a Template-Attribute object.

The response contains the Unique Identifier assigned by the server to the registered object. The server SHALL copy the Unique Identifier returned by this operations into the ID Placeholder variable. The Initial Date attribute of the object SHALL be set to the current time.

Request Payload
Object	REQUIRED	Description
Object Type, see 3.3	Yes	Determines the type of object being registered.
Template-Attribute, see 2.1.8	Yes	Specifies desired object attributes using templates and/or individual attributes.
Certificate, Symmetric Key, Private Key, Public Key, Split Key, Template Secret Data or Opaque Object, see 2.2	No	The object being registered. The object and attributes MAY be wrapped. Some objects (e.g., Private Keys), MAY be omitted from the request.

If a Managed Cryptographic Object is registered, then the following attributes SHALL be included in the Register request, either explicitly, or via specification of a template that contains the attribute.

Attribute	REQUIRED
Cryptographic Algorithm, see 3.4	Yes, MAY be omitted only if this information is encapsulated in the Key Block. Does not apply to Secret Data. If present, then Cryptographic Length below SHALL also be present.
Cryptographic Length, see 3.5	Yes, MAY be omitted only if this information is encapsulated in the Key Block. Does not apply to Secret Data. If present, then Cryptographic Algorithm above SHALL also be present.
Cryptographic Usage Mask, see 3.14	Yes.

Table 115: Register Attribute Requirements

4.4 Re-key

This request is used to generate a replacement key for an existing symmetric key. It is analogous to the Create operation, except that attributes of the replacement key are copied from the existing key, with the exception of the attributes listed in Table 117.

As the replacement key takes over the name attribute of the existing key, Re-key SHOULD only be performed once on a given key.

The server SHALL copy the Unique Identifier of the replacement key returned by this operation into the ID Placeholder variable.

As a result of Re-key, the Link attribute of the existing key is set to point to the replacement key and vice versa.

An Offset MAY be used to indicate the difference between the Initialization Date and the Activation Date of the replacement key. If no Offset is specified, the Activation Date, Process Start Date, Protect Stop Date and Deactivation Date values are copied from the existing key. If Offset is set and dates exist for the existing key, then the dates of the replacement key SHALL be set based on the dates of the existing key as follows:

Attribute in Existing Key	Attribute in Replacement Key
Initial Date (IT₁)	Initial Date (IT₂) > IT₁
Activation Date (AT₁)	Activation Date (AT₂) = IT₂+ Offset
Process Start Date (CT₁)	Process Start Date = CT₁+(AT₂- AT₁)
Protect Stop Date (TT₁)	Protect Stop Date = TT₁+(AT₂- AT₁)
Deactivation Date (DT₁)	Deactivation Date = DT₁+(AT₂- AT₁)

4.5 Derive Key

This request is used to derive a symmetric key or Secret Data object from a key or secret data that is already known to the key management system. The request SHALL only apply to Managed Cryptographic Objects that have the Derive Key bit set in the Cryptographic Usage Mask attribute of the specified Managed Object (i.e., are able to be used for key derivation). If the operation is issued for an object that does not have this bit set, then the server SHALL return an error. For all derivation methods, the client SHALL specify the desired length of the derived key or Secret Data object using the Cryptographic Length attribute. If a key is created, then the client SHALL specify both its Cryptographic Length and Cryptographic Algorithm. If the specified length exceeds the output of the derivation method, then the server SHALL return an error. Clients MAY derive multiple keys and IVs by requesting the creation of a Secret Data object and specifying a Cryptographic Length that is the total length of the derived object. The length SHALL NOT exceed the length of the output returned by the chosen derivation method.

The fields in the request specify the Unique Identifiers of the keys or Secret Data objects to be used for derivation (e.g., some derivation methods MAY require multiple keys or Secret Data objects to derive the result), the method to be used to perform the derivation, and any parameters needed by the specified method. The method is specified as an enumerated value. Currently defined derivation methods include:

· PBKDF2 – This method is used to derive a symmetric key from a password or pass phrase. The PBKDF2 method is published in [PKCS#5] and [RFC2898].

· HASH – This method derives a key by computing a hash over the derivation key or the derivation data.

· HMAC – This method derives a key by computing an HMAC over the derivation data.

· ENCRYPT – This method derives a key by encrypting the derivation data.

· NIST800-108-C – This method derives a key by computing the KDF in Counter Mode as specified in [SP800-108].

· NIST800-108-F – This method derives a key by computing the KDF in Feedback Mode as specified in [SP800-108].

· NIST800-108-DPI – This method derives a key by computing the KDF in Double-Pipeline Iteration Mode as specified in [SP800-108].

· Extensions

The server SHALL perform the derivation function, and then register the derived object as a new Managed Object, returning the new Unique Identifier for the new object in the response. The server SHALL copy the Unique Identifier returned by this operation into the ID Placeholder variable.

As a result of Derive Key, the Link attributes (i.e., Derived Key Link in the objects from which the key is derived, and the Derivation Base Object Link in the derived key) of all objects involved SHALL be set to point to the corresponding objects.

Request Payload
Object	REQUIRED	Description
Object Type, see 3.3	Yes	Determines the type of object to be created.
Unique Identifier, see 3.1	Yes. MAY be repeated	Determines the object or objects to be used to derive a new key. At most, two identifiers MAY be specified: one for the derivation key and another for the secret data. Note that the current value of the ID Placeholder SHALL NOT be used in place of a Unique Identifier in this operation.
Derivation Method, see 9.1.3.2.20	Yes	An Enumeration object specifying the method to be used to derive the new key.
Derivation Parameters, see below	Yes	A Structure object containing the parameters needed by the specified derivation method.
Template-Attribute, see 2.1.8	Yes	Specifies desired object attributes using templates and/or individual attributes; the length and algorithm SHALL always be specified for the creation of a symmetric key.

Response Payload
Object	REQUIRED	Description
Unique Identifier, see 3.1	Yes	The Unique Identifier of the newly derived key or Secret Data object.
Template-Attribute, see 2.1.8	No	An OPTIONAL list of object attributes with values that were not specified in the request, but have been implicitly set by the key management server.

Table 121: Derive Key Response Payload

The Derivation Parameters for all derivation methods consist of the following parameters, except PBKDF2, which requires two additional parameters.

Object	Encoding	REQUIRED
Derivation Parameters	Structure	Yes
Cryptographic Parameters, see 3.6	Structure	Yes, except for HMAC derivation keys.
Initialization Vector	Byte String	No, depends on PRF and mode of operation: empty IV is assumed if not provided.
Derivation Data	Byte String	Yes, unless the Unique Identifier of a Secret Data object is provided.

Table 122: Derivation Parameters Structure (Except PBKDF2)

Cryptographic Parameters identify the Pseudorandom Function (PRF) or the mode of operation of the PRF (e.g., if a key is to be derived using the HASH derivation method, then clients are REQUIRED to indicate the hash algorithm inside Cryptographic Parameters; similarly, if a key is to be derived using AES in CBC mode, then clients are REQUIRED to indicate the Block Cipher Mode). The server SHALL verify that the specified mode matches one of the instances of Cryptographic Parameters set for the corresponding key. If Cryptographic Parameters are omitted, then the server SHALL select the Cryptographic Parameters with the lowest Attribute Index for the specified key. If the corresponding key does not have any Cryptographic Parameters attribute, or if no match is found, then an error is returned.

If a key is derived using HMAC, then the attributes of the derivation key provide enough information about the PRF and the Cryptographic Parameters are ignored.

Derivation Data is either the data to be encrypted, hashed, or HMACed. For the NIST SP 800-108 methods [SP800-108], Derivation Data is Label||{0x00}||Context, where the all-zero byte is OPTIONAL.

Most derivation methods (e.g., ENCRYPT) require a derivation key and the derivation data to be used. The HASH derivation method requires either a derivation key or derivation data. Derivation data MAY either be explicitly provided by the client with the Derivation Data field or implicitly provided by providing the Unique Identifier of a Secret Data object. If both are provided, then an error SHALL be returned.

The PBKDF2 derivation method requires two additional parameters:

Object	Encoding	REQUIRED
Derivation Parameters	Structure	Yes
Cryptographic Parameters, see 3.6	Structure	No, depends on the PRF
Initialization Vector	Byte String	No, depends on the PRF (if different than those defined in [PKCS#5]) and mode of operation: an empty IV is assumed if not provided.
Derivation Data	Byte String	Yes, unless the Unique Identifier of a Secret Data object is provided.

4.6 Certify

This request is used to generate a Certificate object for a public key. This request supports certification of a new public key as well as certification of a public key that has already been certified (i.e., certificate update). Only a single certificate SHALL be requested at a time. Server support for this operation is OPTIONAL, as it requires that the key management system have access to a certification authority (CA). If the server does not support this operation, an error SHALL be returned.

The Certificate Request is passed as a Byte String, which allows multiple certificate request types for X.509 certificates (e.g., PKCS#10, PEM, etc) or PGP certificates to be submitted to the server.

The generated Certificate object whose Unique Identifier is returned MAY be obtained by the client via a Get operation in the same batch, using the ID Placeholder mechanism.

As a result of Certify, the Link attribute of the Public Key and of the generated certificate SHALL be set to point at each other.

The server SHALL copy the Unique Identifier of the generated certificate returned by this operation into the ID Placeholder variable.

If the information in the Certificate Request conflicts with the attributes specified in the Template-Attribute, then the information in the Certificate Request takes precedence.

Request Payload
Object	REQUIRED	Description
Unique Identifier, see 3.1	No	The Unique Identifier of the Public Key being certified. If omitted, then the ID Placeholder value is used by the server as the Unique Identifier.
Certificate Request Type, see 9.1.3.2.21	Yes	An Enumeration object specifying the type of certificate request.
Certificate Request	Yes	A Byte String object with the certificate request.
Template-Attribute, see 2.1.8	No	Specifies desired object attributes using templates and/or individual attributes.

Response Payload
Object	REQUIRED	Description
Unique Identifier, see 3.1	Yes	The Unique Identifier of the generated Certificate object.
Template-Attribute, see 2.1.8	No	An OPTIONAL list of object attributes with values that were not specified in the request, but have been implicitly set by the key management server.

Table 125: Certify Response Payload

4.7 Re-certify

This request is used to renew an existing certificate for the same key pair. Only a single certificate SHALL be renewed at a time. Server support for this operation is OPTIONAL, as it requires that the key management system to have access to a certification authority (CA). If the server does not support this operation, an error SHALL be returned.

The Certificate Request is passed as a Byte String, which allows multiple certificate request types for X.509 certificates (e.g., PKCS#10, PEM, etc) or PGP certificates to be submitted to the server.

The server SHALL copy the Unique Identifier of the new certificate returned by this operation into the ID Placeholder variable.

If the information in the Certificate Request field in the request conflicts with the attributes specified in the Template-Attribute, then the information in the Certificate Request takes precedence.

As the new certificate takes over the name attribute of the existing certificate, Re-certify SHOULD only be performed once on a given (existing) certificate.

The Link attribute of the existing certificate and of the new certificate are set to point at each other. The Link attribute of the Public Key is changed to point to the new certificate.

An Offset MAY be used to indicate the difference between the Initialization Date and the Activation Date of the new certificate. If Offset is set, then the dates of the new certificate SHALL be set based on the dates of the existing certificate (if such dates exist) as follows:

Attribute in Existing Certificate	Attribute in New Certificate
Initial Date (IT₁)	Initial Date (IT₂) > IT₁
Activation Date (AT₁)	Activation Date (AT₂) = IT₂+ Offset
Deactivation Date (DT₁)	Deactivation Date = DT₁+(AT₂- AT₁)

Table 126: Computing New Dates from Offset during Re-certify

Attributes that are not copied from the existing certificate and that are handled in a specific way for the new certificate are:

Attribute	Action
Initial Date, see 3.18	Set to current time
Destroy Date, see 3.23	Not set
Revocation Reason, see 3.26	Not set
Unique Identifier, see 3.2	New value generated
Name, see 3.2	Set to the name(s) of the existing certificate; all name attributes are removed from the existing certificate.
State, see 3.17	Set based on attributes values, such as dates, as shown in Table 126
Digest, see 3.12	Recomputed from the new certificate value.
Link, see 3.29	Set to point to the existing certificate as the replaced certificate.
Last Change Date, see 3.32	Set to current time

Table 129: Re-certify Response Payload

4.8 Locate

This operation requests that the server search for one or more Managed Objects depending on the attributes specified in the request. All attributes are allowed to be used. However, Attribute Index values SHOULD NOT be specified in the request. Attribute Index values that are provided SHALL be ignored by the Locate operation. The request MAY also contain a Maximum Items field, which specifies the maximum number of objects to be returned. If the Maximum Items field is omitted, then the server MAY return all objects matched, or MAY impose an internal maximum limit due to resource limitations.

If more than one object satisfies the identification criteria specified in the request, then the response MAY contain Unique Identifiers for multiple Managed Objects. Returned objects SHALL match all of the attributes in the request. If no objects match, then an empty response payload is returned. If no attribute is specified in the request, any object SHALL be deemed to match the Locate request.

The server returns a list of Unique Identifiers of the found objects, which then MAY be retrieved using the Get operation. If the objects are archived, then the Recover and Get operations are REQUIRED to be used to obtain those objects. If a single Unique Identifier is returned to the client, then the server SHALL copy the Unique Identifier returned by this operation into the ID Placeholder variable. If the Locate operation matches more than one object, and the Maximum Items value is omitted in the request, or is set to a value larger than one, then the server SHALL empty the ID Placeholder, causing any subsequent operations that are batched with the Locate, and which do not specify a Unique Identifier explicitly, to fail. This ensures that these batched operations SHALL proceed only if a single object is returned by Locate.

Wild-cards or regular expressions (defined, e.g., in [ISO/IEC 9945-2]) MAY be supported by specific key management system implementations for matching attribute fields when the field type is a Text String or a Byte String.

The Date attributes in the Locate request (e.g., Initial Date, Activation Date, etc) are used to specify a time or a time range for the search. If a single instance of a given Date attribute is used in the request (e.g., the Activation Date), then objects with the same Date attribute are considered to be matching candidate objects. If two instances of the same Date attribute are used (i.e., with two different values specifying a range), then objects for which the Date attribute is inside or at a limit of the range are considered to be matching candidate objects. If a Date attribute is set to its largest possible value, then it is equivalent to an undefined attribute. The KMIP Usage Guide [KMIP-UG] provides examples.

When the Cryptographic Usage Mask attribute is specified in the request, candidate objects are compared against this field via an operation that consists of a logical AND of the requested mask with the mask in the candidate object, and then a comparison of the resulting value with the requested mask. For example, if the request contains a mask value of 10001100010000, and a candidate object mask contains 10000100010000, then the logical AND of the two masks is 10000100010000, which is compared against the mask value in the request (10001100010000) and the match fails. This means that a matching candidate object has all of the bits set in its mask that are set in the requested mask, but MAY have additional bits set.

When the Usage Allocation attribute is specified in the request, matching candidate objects SHALL have an Object or Byte Count and Total Objects or Bytes equal to or larger than the values specified in the request.

When an attribute that is defined as a structure is specified, all of the structure fields are not REQUIRED to be specified. For instance, for the Link attribute, if the Linked Object Identifier value is specified without the Link Type value, then matching candidate objects have the Linked Object Identifier as specified, irrespective of their Link Type.

The Storage Status Mask field (see Section 9.1.3.3.2) is used to indicate whether only on-line objects, only archived objects, or both on-line and archived objects are to be searched. Note that the server MAY store attributes of archived objects in order to expedite Locate operations that search through archived objects.

Request Payload
Object	REQUIRED	Description
Maximum Items	No	An Integer object that indicates the maximum number of object identifiers the server MAY return.
Storage Status Mask, see 9.1.3.3.2	No	An Integer object (used as a bit mask) that indicates whether only on-line objects, only archived objects, or both on-line and archived objects are to be searched. If omitted, then on-line only is assumed.
Attribute, see 3	No, MAY be repeated	Specifies an attribute and its value(s) that are REQUIRED to match those in a candidate object (according to the matching rules defined above).

Unique Identifier, see 3.1	No, MAY be repeated	The Unique Identifier of the located objects.

Table 131: Locate Response Payload

4.9 Check

This operation requests that the server check for the use of a Managed Object according to values specified in the request. This operation SHOULD only be used when placed in a batched set of operations, usually following a Locate, Create, Create Pair, Derive Key, Certify, Re-Certify or Re-Key operation, and followed by a Get operation.

If the server determines that the client is allowed to use the object according to the specified attributes, then the server returns the Unique Identifier of the object.

If the server determines that the client is not allowed to use the object according to the specified attributes, then the server empties the ID Placeholder and does not return the Unique Identifier, and the operation returns the set of attributes specified in the request that caused the server policy denial. The only attributes returned are those that resulted in the server determining that the client is not allowed to use the object, thus allowing the client to determine how to proceed. The operation also returns a failure, and the server SHALL ignore any subsequent operations in the batch.

The additional objects that MAY be specified in the request are limited to:

· Usage Limits Count (see Section 3.16) – The request MAY contain the usage amount that the client deems necessary to complete its needed function. This does not require that any subsequent Get Usage Allocation operations request this amount. It only means that the client is ensuring that the amount specified is available.

· Cryptographic Usage Mask – This is used to specify the cryptographic operations for which the client intends to use the object (see Section 3.14). This allows the server to determine if the policy allows this client to perform these operations with the object. Note that this MAY be a different value from the one specified in a Locate operation that precedes this operation. Locate, for example, MAY specify a Cryptographic Usage Mask requesting a key that MAY be used for both Encryption and Decryption, but the value in the Check operation MAY specify that the client is only using the key for Encryption at this time.

· Lease Time – This specifies a desired lease time (see Section 3.15). The client MAY use this to determine if the server allows the client to use the object with the specified lease or longer. Including this attribute in the Check operation does not actually cause the server to grant a lease, but only indicates that the requested lease time value MAY be granted if requested by a subsequent, batched, Obtain Lease operation.

Note that these objects are not encoded in an Attribute structure as shown in Section 2.1.1

4.13 Add Attribute

This request adds a new attribute instance to a Managed Object and sets its value. The request contains the Unique Identifier of the Managed Object to which the attribute pertains, along with the attribute name and value. For non-multi-instance attributes, this is how the attribute value is created. For multi-instance attributes, this is how the first and subsequent values are created. Existing attribute values SHALL only be changed by the Modify Attribute operation. Read-Only attributes SHALL NOT be added using the Add Attribute operation. No Attribute Index SHALL be specified in the request. The response returns a new Attribute Index, although the Attribute Index MAY be omitted if the index of the added attribute instance is 0. Multiple Add Attribute requests MAY be included in a single batched request to add multiple attributes.

This request modifies the value of an existing attribute instance associated with a Managed Object. The request contains the Unique Identifier of the Managed Object whose attribute is to be modified, and the attribute name, OPTIONAL Attribute Index, and the new value. Only existing attributes MAY be changed via this operation. New attributes SHALL only be added by the Add Attribute operation. If an Attribute Index is specified, then only the specified instance of the attribute is modified. If the attribute has multiple instances, and no Attribute Index is specified in the request, then the Attribute Index is assumed to be 0. If the attribute does not support multiple instances, then the Attribute Index SHALL NOT be specified. Specifying an Attribute Index for which there exists no Attribute Value SHALL result in an error.

4.15 Delete Attribute

This request deletes an attribute associated with a Managed Object. The request contains the Unique Identifier of the Managed Object whose attribute is to be deleted, the attribute name, and optionally the Attribute Index of the attribute. Attributes that are always required to have a value SHALL never be deleted by this operation. If no Attribute Index is specified, and the Attribute whose name is specified has multiple instances, then the operation is rejected. Note that only a single attribute instance SHALL be deleted at a time. Multiple delete operations (e.g., possibly batched) are necessary to delete several attribute instances. Attempting to delete a non-existent attribute or specifying an Attribute Index for which there exists no Attribute Value SHALL result in an error.

4.16 Obtain Lease

This request is used to obtain a new Lease Time for a specified Managed Object. The Lease Time is an interval value that determines when the client's internal cache of information about the object expires and needs to be renewed. If the returned value of the lease time is zero, then the server is indicating that no lease interval is effective, and the client MAY use the object without any lease time limit. If a client's lease expires, then the client SHALL NOT use the associated cryptographic object until a new lease is obtained. If the server determines that a new lease SHALL NOT be issued for the specified cryptographic object, then the server SHALL respond to the Obtain Lease request with an error.

The response payload for the operation contains the current value of the Last Change Date attribute for the object. This MAY be used by the client to determine if any of the attributes cached by the client need to be refreshed, by comparing this time to the time when the attributes were previously obtained.

Request Payload
Object	REQUIRED	Description
Unique Identifier, see 3.1	No	Determines the object for which the lease is being obtained. If omitted, then the ID Placeholder value is used by the server as the Unique Identifier.

Table 147: Obtain Lease Response Payload

4.17 Get Usage Allocation

This request is used to obtain an allocation from the current Usage Limits value to allow the client to use the Managed Cryptographic Object for applying cryptographic protection. The allocation only applies to Managed Cryptographic Objects that are able to be used for applying protection (e.g., symmetric keys for encryption, private keys for signing, etc.) and is only valid if the Managed Cryptographic Object has a Usage Limits attribute. Usage for processing cryptographically-protected information (e.g., decryption, verification, etc.) is not limited and is not able to be allocated. A Managed Cryptographic Object that has a Usage Limits attribute SHALL NOT be used by a client for applying cryptographic protection unless an allocation has been obtained using this operation. The operation SHALL only be requested during the time that protection is enabled for these objects (i.e., after the Activation Date and before the Protect Stop Date). If the operation is requested for an object that has no Usage Limits attribute, or is not an object that MAY be used for applying cryptographic protection, then the server SHALL return an error.

The field in the request specifies the number of units that the client needs to protect. If the requested amount is not available or if the Managed Object is not able to be used for applying cryptographic protection at this time, then the server SHALL return an error. The server SHALL assume that the entire allocated amount is going to be consumed. Once the entire allocated amount has been consumed, the client SHALL NOT continue to use the Managed Cryptographic Object for applying cryptographic protection until a new allocation is obtained.

Request Payload
Object	REQUIRED	Description
Unique Identifier, see 3.1	No	Determines the object whose usage allocation is being requested. If omitted, then the ID Placeholder is substituted by the server.

4.19 Revoke

This request is used to revoke a Managed Cryptographic Object or an Opaque Object. The request SHALL NOT specify a Template object. The request contains a reason for the revocation (e.g., “key compromise”, “cessation of operation”, etc). Special authentication and authorization SHOULD be enforced to perform this request (see [KMIP-UG]). Only the object creator or an authorized security officer SHOULD be allowed to issue this request. The operation has one of two effects. If the revocation reason is “key compromise”, then the object is placed into the “compromised” state, and the Compromise Date attribute is set to the current date and time. Otherwise, the object is placed into the “deactivated” state, and the Deactivation Date attribute is set to the current date and time.

Request Payload
Object	REQUIRED	Description
Unique Identifier, see 3.1	No	Determines the object being revoked. If omitted, then the ID Placeholder value is used by the server as the Unique Identifier.

4.20 Destroy

This request is used to indicate to the server that the key material for the specified Managed Object SHALL be destroyed. The meta-data for the key material MAY be retained by the server (e.g., used to ensure that an expired or revoked private signing key is no longer available). Special authentication and authorization SHOULD be enforced to perform this request (see [KMIP-UG]). Only the object creator or an authorized security officer SHOULD be allowed to issue this request. If the Unique Identifier specifies a Template object, then the object itself, including all meta-data, SHALL be destroyed. Cryptographic Objects MAY only be destroyed if they are in either Pre-Active or Deactivated state. A Cryptographic Object in the Active state MAY be destroyed if the server sets the Deactivation date (the state of the object transitions to Deactivated) prior to destroying the object.

Request Payload
Object	REQUIRED	Description
Unique Identifier, see 3.1	No	Determines the object being destroyed. If omitted, then the ID Placeholder value is used by the server as the Unique Identifier.

4.21 Archive

This request is used to specify that a Managed Object MAY be archived. The actual time when the object is archived, the location of the archive, or level of archive hierarchy is determined by the policies within the key management system and is not specified by the client. The request contains the unique identifier of the Managed Object. Special authentication and authorization SHOULD be enforced to perform this request (see [KMIP-UG]). Only the object creator or an authorized security officer SHOULD be allowed to issue this request. This request is only an indication from a client that from its point of view it is possible for the key management system to archive the object.

4.23 Validate

This requests that the server validate a certificate chain and return information on its validity. Only a single certificate chain SHALL be included in each request. Support for this operation at the server is OPTIONAL. If the server does not support this operation, an error SHALL be returned.

The request may contain a list of certificate objects, and/or a list of Unique Identifiers that identify Managed Certificate objects. Together, the two lists compose a certificate chain to be validated. The request MAY also contain a date for which all certificates in the certificate chain are REQUIRED to be valid.

The method or policy by which validation is conducted is a decision of the server and is outside of the scope of this protocol. Likewise, the order in which the supplied certificate chain is validated and the specification of trust anchors used to terminate validation are also controlled by the server.

The server SHALL reply with one of two responses:

If the operation has not completed, the response SHALL contain no payload and a Result Status of Pending.

If the operation has completed, the response SHALL contain the appropriate payload for the operation. This response SHALL be identical to the response that would have been sent if the operation had completed synchronously.

9 Message Encoding

To support different transport protocols and different client capabilities, a number of message-encoding mechanisms are supported.

9.1 TTLV Encoding

In order to minimize the resource impact on potentially low-function clients, one encoding mechanism to be used for protocol messages is a simplified TTLV (Tag, Type, Length, Value) scheme.

The scheme is designed to minimize the CPU cycle and memory requirements of clients that need to encode or decode protocol messages, and to provide optimal alignment for both 32-bit and 64-bit processors. Minimizing bandwidth over the transport mechanism is considered to be of lesser importance.

9.1.1 TTLV Encoding Fields

Every Data object encoded by the TTLV scheme consists of four items, in order:

9.1.1.1 Item Tag

An Item Tag is a three-byte binary unsigned integer, transmitted big endian, which contains a number that designates the specific Protocol Field or Object that the TTLV object represents. To ease debugging, and to ensure that malformed messages are detected more easily, all tags SHALL contain either the value 42 in hex or the value 54 in hex as the high order (first) byte. Tags defined by this specification contain hex 42 in the first byte. Extensions, which are permitted, but are not defined in this specification, contain the value 54 hex in the first byte. A list of defined Item Tags is in Section 9.1.3.1

9.1.1.2 Item Type

An Item Type is a byte containing a coded value that indicates the data type of the data object. The allowed values are:

Data Type	Coded Value in Hex
Structure	01
Integer	02
Long Integer	03
Big Integer	04
Enumeration	05
Boolean	06
Text String	07
Byte String	08
Date-Time	09
Interval	0A

Table 191: Allowed Item Type Values

9.1.1.3 Item Length

An Item Length is a 32-bit binary integer, transmitted big-endian, containing the number of bytes in the Item Value. The allowed values are:

Data Type	Length
Structure	Varies, multiple of 8
Integer	4
Long Integer	8
Big Integer	Varies, multiple of 8
Enumeration	4
Boolean	8
Text String	Varies
Byte String	Varies
Date-Time	8
Interval	4

Table 192: Allowed Item Length Values

If the Item Type is Structure, then the Item Length is the total length of all of the sub-items contained in the structure, including any padding. If the Item Type is Integer, Enumeration, Text String, Byte String, or Interval, then the Item Length is the number of bytes excluding the padding bytes. Text Strings and Byte Strings SHALL be padded with the minimal number of bytes following the Item Value to obtain a multiple of eight bytes. Integers, Enumerations, and Intervals SHALL be padded with four bytes following the Item Value.

9.1.1.4 Item Value

The item value is a sequence of bytes containing the value of the data item, depending on the type:

· Integers are encoded as four-byte long (32 bit) binary signed numbers in 2's complement notation, transmitted big-endian.

· Long Integers are encoded as eight-byte long (64 bit) binary signed numbers in 2's complement notation, transmitted big-endian.

· Big Integers are encoded as a sequence of eight-bit bytes, in two's complement notation, transmitted big-endian. If the length of the sequence is not a multiple of eight bytes, then Big Integers SHALL be padded with the minimal number of leading sign-extended bytes to make the length a multiple of eight bytes. These padding bytes are part of the Item Value and SHALL be counted in the Item Length.

· Enumerations are encoded as four-byte long (32 bit) binary unsigned numbers transmitted big-endian. Extensions, which are permitted, but are not defined in this specification, contain the value 8 hex in the first nibble of the first byte.

· Booleans are encoded as an eight-byte value that SHALL either contain the hex value 0000000000000000, indicating the Boolean value False, or the hex value 0000000000000001, transmitted big-endian, indicating the Boolean value True.

· Text Strings are sequences of bytes that encode character values according to the UTF-8 encoding standard. There SHALL NOT be null-termination at the end of such strings.

· Byte Strings are sequences of bytes containing individual unspecified eight-bit binary values, and are interpreted in the same sequence order.

· Date-Time values are POSIX Time values encoded as Long Integers. POSIX Time, as described in IEEE Standard 1003.1 [IEEE1003-1], is the number of seconds since the Epoch (1970 Jan 1, 00:00:00 UTC), not counting leap seconds.

· Intervals are encoded as four-byte long (32 bit) binary unsigned numbers, transmitted big-endian. They have a resolution of one second.

· Structure Values are encoded as the concatenated encodings of the elements of the structure. All structures defined in this specification SHALL have all of their fields encoded in the order in which they appear in their respective structure descriptions.

12 Server Baseline Implementation Conformance Profile

The intention of the baseline conformance profile is for the minimal KMIP Server to support the mechanics of communication and to support a limited set of commands, such as query. The minimal KMIP Server would not need to support any particular algorithm – this would be the work of additional profiles.

An implementation is a conforming KMIP Server if the implementation meets the conditions in Section 12.1.

An implementation SHALL be a conforming KMIP Server.

If an implementation claims support for a particular clause, then the implementation SHALL conform to all normative statements within that clause and any subclauses to that clause.

12.1 Conformance clauses for a KMIP Server

An implementation conforms to this specification as a KMIP Server if it meets the following conditions:

Supports the following client-to-server operations:

Locate (see 4.8)
Check (see 4.9)
Get (see 4.10)
Get Attribute (see 4.11)
Get Attribute List (see 4.12)
Add Attribute (see 4.13)
