Description of Working Group:
The PKIX Working Group was established in the Fall of 1995 with the intent of developing Internet standards needed to support an X.509-based PKI. The scope of PKIX work has expanded beyond this initial goal. PKIX not only profiles ITU PKI standards, but also develops new standards apropos to the use of X.509-based PKIs in the Internet.

PKIX has produced several informational and standards track documents in support of the original and revised scope of the WG. The first of these standards, RFC 2459, profiled X.509 version 3 certificates and version 2 CRLs for use in the Internet. Profiles for the use of Attribute Certificates (RFC XXXX [pending]), LDAP v2 for certificate and CRL storage (RFC 2587), the Internet X.509 Public Key Infrastructure Qualified Certificates Profile (RFC 3039), and the Internet X.509 Public Key Infrastructure Certificate Policy and certification Practices Framework (RFC 2527 - Informational) are in line with the initial scope.

The Certificate Management Protocol (CMP) (RFC 2510), the Online Certificate Status Protocol (OCSP) (RFC 2560), Certificate Management Request Format (CRMF) (RFC 2511), Time-Stamp Protocol (RFC 3161), Certificate Management Messages over CMS (RFC 2797), Internet X.509 Public Key Infrastructure Time Stamp Protocols (RFC 3161), and the use of FTP and HTTP for transport of PKI operations (RFC 2585) are representative of the expanded scope of PKIX, as these are new protocols developed in the working group, not profiles of ITU PKI standards.

A roadmap, providing a guide to the growing set of PKIX document, also has been developed as an informational RFC.

Ongoing PKIX Work items

An ongoing PKIX task is the progression of existing, standards track RFCs from PROPOSED to DRAFT. Also, to the extent that PKIX work relates to protocols from other areas, e.g., LDAP, it is necessary to track the evolution of the other protocols and produce updated RFCs. For example, the LDAP v2 documents from PKIX are evolving to address LDAP v3. Finally, since the profiling of X.509 standards for use in the Internet remains a major focus, the WG will continue to track the evolution of these standards and incorporate changes and additions as appropriate.

New Work items for PKIX

- production of a requirements RFC for delegated path discovery and path validation protocols (DPD/DPV) and subsequent production of RFCs for protocols that satisfy the requirements

- development of a logotype extension for certificates

- development of a proxy certificate extension and associated processing rules

- development of an informational document on PKI disaster recovery

These work items may become standards track, INFORMATIONAL or EXPERIMENTAL RFCs, or may not even be published as RFCs.

Other deliverables may be agreed upon as extensions are proposed. New deliverables must be approved by the Security Area Directors before inclusion on the charter or IETF meeting agendas.
