IETF PKIX Working Group
The PKIX (Public-Key Infrastructure X.509) Working Group (PKIX-WG) was assigned — by the Internet Engineering Task Force (IETF) — to develop the necessary Internet standards needed to support a Public Key Infrastructure, based on the X.509 protocol. The working group (WG) was established circa fall of 1995.
Scope and Standards
Although the PKIX-WG has accomplished its initial assignment, it was never dissolved — as is commonplace with WGs which exceed their initial scope of work.
Presently, the PKIX-WG profiles PKI standards of the International Telecommunication Union, and develops new standards apropos to the use of X.509-based PKIs with the Internet:
- Profiled X.509 version 3 certificates and version 2 Certificate Revocation Lists (CRL) for use with the Internet (RFC 2459)
- The Internet X.509 Public Key Infrastructure Qualified Certificates Profile (RFC 3039)
- The Internet X.509 Public Key Infrastructure Certificate Policy and certification Practices Framework (RFC 2527 - Informational)
- Profiles for the use of Attribute Certificates (RFC [undetermined])
- LDAP (Lightweight Directory Access Protocol) v2 for certificate and CRL storage (RFC 2587)
