1 Introduction (Non-Normative)

This specification describes the use of the X.509 authentication framework with the Web Services Security: SOAP Message Security specification [WS-Security].

An X.509 certificate specifies a binding between a public key and a set of attributes that includes (at least) a subject name, issuer name, serial number and validity interval. This binding may be subject to subsequent revocation advertised by mechanisms that include issuance of CRLs, OCSP tokens or mechanisms that are outside the X.509 framework, such as XKMS.

An X.509 certificate may be used to validate a public key that may be used to authenticate a SOAP message or to identify the public key with a SOAP message that has been encrypted.

Note that Sections 2.1, 2.2, all of 3, and indicated parts of 5 are normative. All other sections are non-normative.

2 Notations and Terminology (Normative)

This section specifies the notations, namespaces and terminology used in this specification.

2.1 Notational Conventions

The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.

When describing abstract data models, this specification uses the notational convention used by the XML Infoset. Specifically, abstract property names always appear in square brackets (e.g., [some property]).

When describing concrete XML schemas, this specification uses a convention where each member of an element’s [children] or [attributes] property is described using an XPath-like notation (e.g., /x:MyHeader/x:SomeProperty/@value1). The use of {any} indicates the presence of an element wildcard (<xs:any/>). The use of @{any} indicates the presence of an attribute wildcard (<xs:anyAttribute/>).

2.2 Namespaces

Namespace URIs (of the general form "some-URI") represents some application-dependent or context-dependent URI as defined in RFC 3986 [URI]. This specification is designed to work with the general SOAP [SOAP11, SOAP12] message structure and message processing model, and should be applicable to any version of SOAP. The current SOAP 1.1 namespace URI is used herein to provide detailed examples, but there is no intention to limit the applicability of this specification to a single version of SOAP.

The namespaces used in this document are shown in the following table (note that for brevity, the examples use the prefixes listed below but do not include the URIs – those listed below are assumed).

2.3 Terminology

This specification adopts the terminology defined in Web Services Security: SOAP Message Security specification [WS-Security].

Readers are presumed to be familiar with the definitions of terms in the Internet Security Glossary [Glossary].

3 Usage (Normative)

This specification describes the syntax and processing rules for the use of the X.509 authentication framework with the Web Services Security: SOAP Message Security specification [WS-Security]. For the purposes of determining the order of preference of reference types, the use of IssuerSerial within X509Data should be considered to be a form of Key Identifier

3.1 Token types

This profile defines the syntax of, and processing rules for, three types of binary security token using the URI values specified in Table 2.

If the ValueType attribute is missing, the receiver may interpret it either based on a prior agreement or by parsing the content.

Token	ValueType URI	Description
Single certificate	#X509v3	An X.509 v3 certificate capable of signature-verification at a minimum
Certificate Path	#X509PKIPathv1	An ordered list of X.509 certificates packaged in a PKIPath
Set of certificates and CRLs	#PKCS7	A list of X.509 certificates and (optionally) CRLs packaged in a PKCS#7 wrapper

Table 2 – Token types

3.1.1 X509v3 Token Type

The type of the end-entity that is authenticated by a certificate used in this manner is a matter of policy that is outside the scope of this specification.

3.1.2 X509PKIPathv1 Token Type

The X509PKIPathv1 token type MAY be used to represent a certificate path.

3.1.3 PKCS7 Token Type

The PKCS7 token type MAY be used to represent a certificate path. It is RECOMMENDED that applications use the PKIPath object for this purpose instead.

The order of the certificates in a PKCS#7 data structure is not significant. If an ordered certificate path is converted to PKCS#7 encoded bytes and then converted back, the order of the certificates may not be preserved. Processors SHALL NOT assume any significance to the order of the certificates in the data structure. See [PKCS7] for more information.

3.2 Token References

In order to ensure a consistent processing model across all the token types supported by WSS: SOAP Message Security, the <wsse:SecurityTokenReference> element SHALL be used to specify all references to X.509 token types in signature or encryption elements that comply with this profile.

A <wsse:SecurityTokenReference> element MAY reference an X.509 token type by one of the following means:

· Reference to a Subject Key Identifier
The <wsse:SecurityTokenReference> element contains a <wsse:KeyIdentifier> element that specifies the token data by means of a X.509 SubjectKeyIdentifier reference. A subject key identifier MAY only be used to reference an X.509v3 certificate.”

· Reference to a Binary Security Token
The <wsse:SecurityTokenReference> element contains a wsse:Reference> element that references a local <wsse:BinarySecurityToken> element or a remote data source that contains the token data itself.

· Reference to an Issuer and Serial Number
The <wsse:SecurityTokenReference> element contains a <ds:X509Data> element that contains a <ds:X509IssuerSerial> element that uniquely identifies an end entity certificate by its X.509 Issuer and Serial Number.

3.2.1 Reference to an X.509 Subject Key Identifier

The <wsse:KeyIdentifier> element is used to specify a reference to an X.509v3 certificate by means of a reference to its X.509 SubjectKeyIdentifier attribute. This profile defines the syntax of, and processing rules for referencing a Subject Key Identifier using the URI values specified in Table 3 (note that URI fragments are relative to http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0).

Subject Key Identifier	ValueType URI	Description
Certificate Key Identifier	#X509SubjectKeyIdentifier	Value of the certificate’s X.509 SubjectKeyIdentifier

Table 3 – Subject Key Identifier

The <wsse:SecurityTokenReference> element from which the reference is made contains the <wsse:KeyIdentifier> element. The <wsse:KeyIdentifier> element MUST have a ValueType attribute with the value #X509SubjectKeyIdentifier and its contents MUST be the value of the certificate’s X.509v3 SubjectKeyIdentifier extension, encoded as per the <wsse:KeyIdentifier> element’s EncodingType attribute. For the purposes of this specification, the value of the SubjectKeyIdentifier extension is the contents of the KeyIdentifier octet string, excluding the encoding of the octet string prefix.

3.2.2 Reference to a Security Token

The <wsse:Reference> element is used to reference an X.509 security token value by means of a URI reference.

The URI reference MAY be internal in which case the URI reference SHOULD be a bare name XPointer reference to a <wsse:BinarySecurityToken> element contained in a preceding message header that contains the binary X.509 security token data.

3.2.3 Reference to an Issuer and Serial Number

The <ds:X509IssuerSerial> element is used to specify a reference to an X.509 security token by means of the certificate issuer name and serial number.

The <ds:X509IssuerSerial> element is a direct child of the <ds:X509Data> element that is in turn a direct child of the <wsse:SecurityTokenReference> element in which the reference is made

3.3 Signature

Signed data MAY specify the certificate associated with the signature using any of the X.509 security token types and references defined in this specification.

An X.509 certificate specifies a binding between a public key and a set of attributes that includes (at least) a subject name, issuer name, serial number and validity interval. Other attributes may specify constraints on the use of the certificate or affect the recourse that may be open to a relying party that depends on the certificate. A given public key may be specified in more than one X.509 certificate; consequently a given public key may be bound to two or more distinct sets of attributes.

It is therefore necessary to ensure that a signature created under an X.509 certificate token uniquely and irrefutably specifies the certificate under which the signature was created.

Implementations SHOULD protect against a certificate substitution attack by including either the certificate itself or an immutable and unambiguous reference to the certificate within the scope of the signature according to the method used to reference the certificate as described in the following sections.

3.3.1 Key Identifier

The <wsse:KeyIdentifier> element does not guarantee an immutable and unambiguous reference to the certificate referenced. Consequently implementations that use this form of reference within a signature SHOULD employ the STR Dereferencing Transform within a reference to the signature key information in order to ensure that the referenced certificate is signed, and not just the ambiguous reference. The form of the reference is a bare name reference as defined by the XPointer specification [XPointer].

The following example shows a certificate referenced by means of a KeyIdentifier. The scope of the signature is the <ds:SignedInfo> element which includes both the message body (#body) and the signing certificate by means of a reference to the <ds:KeyInfo> element which references it (#keyinfo). Since the <ds:KeyInfo> element only contains a mutable reference to the certificate rather than the certificate itself, a transformation is specified which replaces the reference to the certificate with the certificate. The <ds:KeyInfo> element specifies the signing key by means of a <wsse:SecurityTokenReference> element which contains a <wsse:KeyIdentifier> element which specifies the X.509 subject key identifier of the signing certificate.

3.3.2 Reference to a Binary Security Token

The signed data SHOULD contain a core bare name reference (as defined by the XPointer specification [XPointer]) to the<wsse:BinarySecurityToken> element that contains the security token referenced, or a core reference to the external data source containing the security token.

The following example shows a certificate embedded in a <wsse:BinarySecurityToken> element and referenced by URI within a signature. The certificate is included in the <wsse:Security> header as a <wsse:BinarySecurityToken> element with identifier binarytoken. The scope of the signature defined by a <ds:Reference> element within the <ds:SignedInfo> element includes the signing certificate which is referenced by means of the URI bare name pointer #binarytoken. The <ds:KeyInfo> element specifies the signing key by means of a <wsse:SecurityTokenReference> element which contains a <wsse:Reference> element which references the certificate by means of the URI bare name pointer #binarytoken.

3.3.3 Reference to an Issuer and Serial Number

The signed data SHOULD contain a core bare name reference (as defined by the XPointer specification [XPointer]) to the <ds:KeyInfo> element that contains the security token reference.

The following example shows a certificate referenced by means of its issuer name and serial number. In this example the certificate is not included in the message. The scope of the signature defined by the <ds:SignedInfo> element includes both the message body (#body) and the key information element (#keyInfo). The <ds:KeyInfo> element contains a <wsse:SecurityTokenReference> element which specifies the issuer and serial number of the specified certificate by means of the <ds:X509IssuerSerial> element.

3.4 Encryption

Encrypted keys or data MAY identify a key required for decryption by identifying the corresponding key used for encryption by means of any of the X.509 security token types or references specified herein.

Since the sole purpose is to identify the decryption key it is not necessary to specify either a trust path or the specific contents of the certificate itself.

The following example shows a decryption key referenced by means of the issuer name and serial number of an associated certificate. In this example the certificate is not included in the message. The <ds:KeyInfo> element contains a <wsse:SecurityTokenReference> element which specifies the issuer and serial number of the specified certificate by means of the <ds:X509IssuerSerial> element.

3.5 Error Codes

When using X.509 certificates, the error codes defined in the WSS: SOAP Message Security specification [WS-Security] MUST be used.

If an implementation requires the use of a custom error it is recommended that a sub-code be defined as an extension of one of the codes defined in the WSS: SOAP Message Security specification [WS-Security]

4 Threat Model and Countermeasures (Non-Normative)

The use of X.509 certificate token introduces no new threats beyond those identified in WSS: SOAP Message Security specification [WS-Security].

Message alteration and eavesdropping can be addressed by using the integrity and confidentiality mechanisms described in WSS: SOAP Message Security [WS-Security]. Replay attacks can be addressed by using message timestamps and caching, as well as other application-specific tracking mechanisms. For X.509 certificates, identity is authenticated by use of keys, man-in-the-middle attacks are generally mitigated.

It is strongly RECOMMENDED that all relevant and immutable message data be signed.

It should be noted that a transport-level security protocol such as SSL or TLS [RFC2246] MAY be used to protect the message and the security token as an alternative to or in conjunction with WSS: SOAP Message Security specification [WS-Security].
