PKIX Specifications

The PKIX group has produced a number of specifications as listed below:

RFC 6960 - X.509 Internet Public Key Infrastructure Online Certificate Status Protocol - OCSP

RFC 6818 - Internet X.509 Public Key Infrastructure -- Updates to the Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile

This document updates RFC 5280, the "Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile". This document changes the set of acceptable encoding methods for the explicitText field of the user notice policy qualifier and clarifies the rules for converting internationalized domain name labels to ASCII. This document also provides some clarifications on the use of self-signed certificates, trust anchors, and some updated security considerations.

RFC 6170 - Internet X.509 Public Key Infrastructure -- Certificate Image

RFC 6024 - Trust Anchor Management Requirements

This informational RFC establishes the requirements on trust anchor information and the management of such information. This includes:

  • Trust store management should be transport independent, i.e., should allow for different communication types.
  • Requirement on type of operations for managing a trust anchor store and how to do selected operation.
  • Different use of trust anchor information.
  • Requirements on what should be included in trust anchor information.
  • Some security consideration.
  • Ensure online trust store management.
  • Disaster recovery

RFC 5937 - Using Trust Anchor Constraints during Certification Path Processing

RFC 5934 - Trust Anchor Management Protocol (TAMP)

This RFC describes a transport independent protocol for the management of trust anchors (TAs) and community identifiers stored in a trust anchor store. The protocol makes use of the Cryptographic Message Syntax (CMS), and a digital signature is used to provide integrity protection and data origin authentication. The protocol can be used to manage trust anchor stores containing trust anchors represented as Certificate, TBSCertificate, or TrustAnchorInfo objects.

RFC 5914 - Trust Anchor Format

This document describes a structure for representing trust anchor information. A trust anchor is an authoritative entity represented by a public key and associated data. The public key is used to verify digital signatures, and the associated data is used to constrain the types of information or actions for which the trust anchor is authoritative. The structures defined in this document are intended to satisfy the format-related requirements defined in Trust Anchor Management Requirements.

RFC 5913 - Clearance Attribute and Authority Clearance Constraints Certificate Extension

RFC 5912 - New ASN.1 Modules for the Public Key Infrastructure Using X.509 (PKIX)

The Public Key Infrastructure using X.509 (PKIX) certificate format, and many associated formats, are expressed using ASN.1. The current ASN.1 modules conform to the 1988 version of ASN.1. This document updates those ASN.1 modules to conform to the 2002 version of ASN.1. There are no bits-on-the-wire changes to any of the formats; this is simply a change to the syntax.

RFC 5816 - ESSCertIDv2 Update for RFC 3161

RFC 5758 - Internet X.509 Public Key Infrastructure: Additional Algorithms and Identifiers for DSA and ECDSA

RFC 5274 - Certificate Management Messages over CMS (CMC): Compliance Requirements

RFC 5273 - Certificate Management over CMS (CMC): Transport Protocols

RFC 5272 - Certificate Management over CMS (CMC)

This document defines the base syntax for CMC, a Certificate Management protocol using the Cryptographic Message Syntax (CMS). This protocol addresses two immediate needs within the Internet Public Key Infrastructure (PKI) community:

  • The need for an interface to public key certification products and services based on CMS and PKCS #10 (Public Key Cryptography Standard), and
  • The need for a PKI enrolment protocol for encryption only keys due to algorithm or hardware design.

CMC also requires the use of the transport document and the requirements usage document along with this document for a full definition.

The Algorithms and Identifiers for the Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile is specified in RFC 3279.

RFC 3161 - Internet X.509 Public Key Infrastructure Time-Stamp Protocol (TSP)

RFC 2875 - Diffie-Hellman Proof-of-Possession Algorithms

This document describes two methods for producing an integrity check value from a Diffie-Hellman key pair. This behavior is needed for such operations as creating the signature of a PKCS #10 certification request. These algorithms are designed to provide a proof-of- possession rather than general purpose signing.

RFC 2585 - Internet X.509 Public Key Infrastructure Operational Protocols: FTP and HTTP

This specification is part of a multi-part standard for the Internet Public Key Infrastructure (PKI) using X.509 certificates and certificate revocation lists (CRLs). This document specifies the conventions for using the File Transfer Protocol (FTP) and the Hypertext Transfer Protocol (HTTP) to obtain certificates and CRLs from PKI repositories. Additional mechanisms addressing PKI repository access are specified in separate documents.
