1 Introduction

OASIS requires a conformance section in an approved committee specification (see [TCProc], section 2.18 Specification Quality):

A specification that is approved by the TC at the Public Review Draft, Committee Specification or OASIS Standard level must include a separate section, listing a set of numbered conformance clauses, to which any implementation of the specification must adhere in order to claim conformance to the specification (or any optional portion thereof).

This document intends to meet this OASIS requirement on conformance clauses for a KMIP Server ([KMIP-Spec] 12.1) through profiles that define the use of KMIP objects, attributes, operations, message elements and authentication methods within specific contexts of KMIP server and client interaction. These profiles define a set of normative constraints for employing KMIP within a particular environment or context of use. They may, optionally, require the use of specific KMIP functionality or in other respects define the processing rules to be followed by profile actors.

For normative definition of the elements of KMIP specified in these profiles, see the KMIP Specification. Illustrative guidance for the implementation of KMIP clients and servers is provided in the KMIP Usage Guide.

1.1 Terminology

2 Profiles

This document defines a selected set of conformance clauses and authentication suites which when “paired together” form KMIP Profiles. The KMIP TC also welcomes proposals for new profiles. KMIP TC members are encouraged to submit these proposals to the KMIP TC for consideration for inclusion in a future version of this TC-approved document. However, some OASIS members may simply wish to inform the committee of profiles or other work related to KMIP.

2.1 Guidelines for Specifying Conformance Clauses

This section provides a checklist of issues that SHALL be addressed by each clause.

1. Implement functionality as mandated by Section 12.1 (Conformance clauses for a KMIP servers)

2. Specify the list of additional objects that SHALL be supported

3. Specify the list of additional attributes that SHALL be supported

4. Specify the list of additional operations that SHALL be supported

5. Specify any additional message content that SHALL be supported

2.2 Guidelines for Specifying Authentication Suites

1. Channel Security – Client to Server communication SHALL establish and maintain channel confidentiality and integrity, and provide assurance of server authenticity

2. Channel Options – Options like protocol version and cipher suite

3. Client Authenticity – The options that are used to provide assurance of client authenticity

2.3 Guidelines for Specifying KMIP Profiles

A KMIP profile is a tuple of {Conformance Clause, Authentication Suite}

3 Authentication suites

This section contains the list of protocol versions and cipher suites that are to be used by profiles contained within this document.

3.1 Basic Authentication Suite

This authentication set stipulates that a KMIP client and server SHALL use TLS to negotiate a mutually-authenticated connection with the exception of the Query operation. The query operation SHALL NOT require the client to provide assurance of its authenticity.

3.1.1 Protocols

Conformant KMIP servers SHALL support TLSv1.0. They MAY support TLS v1.1 [RFC 4346], TLS v1.2 [RFC 5246] bearing in mind that they are not compatible with each other and SHALL NOT support SSLv3.0, SSLv2.0 and SSLv1.0.

3.1.2 Cipher Suites

Conformant KMIP servers SHALL support the following cipher suites:

· TLS_RSA_WITH_AES_128_CBC_SHA

Basic Authentication Suite Conformant KMIP servers MAY support the cipher suites listed in tables 4-1 through 4-4 of NIST 800-57 Part 3 with the exception of NULL ciphers (at the time this document was created, the only NULL cipher in 800-57 Part 3 was: TLS_RSA_WITH_NONE_SHA)

Basic Authentication Suite Conformant KMIP servers SHALL NOT support any other cipher suites.

NOTE: TLS 1.0 has some security issues as described in http://www.openssl.org/~bodo/tls-cbc.txt. Implementations that need protections against this attack should considering using the “TLS 1.2 Authentication Suite”

At the time this document was published, NIST 800-57 Part 3 Table 4-1, for cipher suites that have both SHA1 and SHA256 variants, erroneously categorizes SHA256 based ciphers under TLS versions 1.0, 1.1 and 1.2 and SHA1 based ciphers under TLS 1.2. The correct value for SHA256 based ciphers should 1.2 and for SHA1 based ciphers it should be 1.0, 1.2 and 1.2.

3.1.3 Client Authenticity

For authenticated services (all operations save Query) KMIP servers SHALL require the use of channel (TLS) mutual authentication to provide assurance of client authenticity.

In the absence of Credential information in the request header, KMIP servers SHALL use the identity derived from the channel authentication as the client identity.

In the presence of Credential information in the request header, KMIP servers SHALL consider such Credential information into their evaluation of client authenticity and identity, along with the authenticity and identity derived from the channel. The exact mechanisms for such evaluation are outside the scope of this specification.

3.1.4 Object Creator

KMIP objects have a creator. For those KMIP requests that result in new managed objects the client identity SHALL be used as the creator of the managed object. For those operations that only access pre-existent managed objects, the client identity SHALL be checked against the creator and access SHALL be controlled as detailed in section 3.13 of [KMIP].

3.2 TLS 1.2 Authentication Suite

3.2.1 Protocols

Conformant KMIP servers SHALL support TLSv1.2

3.2.2 Cipher Suites

Conformant KMIP servers SHALL support the following cipher suites:

· TLS_RSA_WITH_AES_256_CBC_SHA256

· TLS_RSA_WITH_AES_128_CBC_SHA256

TLS 1.2 Authentication Suite Conformant KMIP servers MAY support the cipher suites listed in tables 4-1 through 4-4 of NIST 800-57 Part 3 with the exception of NULL ciphers (at the time this document was created, the only NULL cipher in 800-57 Part 3 was: TLS_RSA_WITH_NONE_SHA)

TLS 1.2 Authentication Suite Conformant KMIP servers SHALL NOT support any other cipher suites

NIST 800-57 Part 3 Table 4-1, for cipher suites that have both SHA1 and SHA256 variants, erroneously categorizes SHA256 based ciphers under TLS versions 1.0, 1.1 and 1.2 and SHA1 based ciphers under TLS 1.2. The correct value for SHA256 based ciphers should 1.2 and for SHA1 based ciphers it should be 1.0, 1.2 and 1.2.

3.2.3 Client Authenticity

Same as the basic authentication suite (See Section 3.1.3)

3.2.4 Object Creator

Same as the basic authentication suite (See Section 3.1.4)

4 KMIP Profiles

This section lists the KMIP profiles that are defined in this specification. More than one profile may be supported at the same time provided there are no conflicting requirements.

4.1 Secret Data KMIP Profile

A profile that consists of the tuple {Secret Data Server Conformance Clause, Basic Authentication Suite}

4.2 Basic Symmetric Key Store and Server KMIP Profile

A profile that consists of the tuple {Basic Symmetric Key Store and Server Conformance Clause, Basic Authentication Suite}

4.3 Basic Symmetric Key Foundry and Server KMIP Profile

A profile that consists of the tuple {Basic Symmetric Key Foundry and Server Conformance Clause, Basic Authentication Suite}

4.4 Secret Data TLS 1.2 Authentication KMIP Profile

A profile that consists of the tuple {Secret Data Server Conformance Clause, TLS 1.2 Authentication Suite}

4.5 Basic Symmetric Key Store and Server TLS 1.2 Authentication KMIP Profile

A profile that consists of the tuple {Basic Symmetric Key Store and Server Conformance Clause, TLS 1.2 Authentication Suite}

4.6 Basic Symmetric Key Foundry and Server TLS 1.2 Authentication KMIP Profile

A profile that consists of the tuple {Basic Symmetric Key Foundry and Server Conformance Clause, TLS 1.2 Authentication Suite}

5 Conformance Clauses

The following subsections describe currently-defined profiles related to the use of KMIP in support of secret data and symmetric key operations.

5.1 Secret Data Server Clause

This proposal builds on the KMIP server conformance clauses to provide some of the most basic functionality that would be expected of a conformant KMIP server – the ability to create, register and get secret data in an interoperable fashion.

5.1.1 Implementation Conformance

An implementation is a conforming Secret Data Server Clause if it meets the conditions as outlined in the following section.

5.1.2 Conformance of a Secret Data Server

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

Supports the conditions required by the KMIP Server conformance clauses ([KMIP-Spec] 12.1)
