            Multiple Public-Key Algorithm X.509 Certificates
                draft-truskovsky-lamps-pq-hybrid-x509-01

Abstract

   This document describes a method of embedding alternative sets of
   cryptographic materials into X.509v3 digital certificates, X.509v2
   Certificate Revocation Lists (CRLs), and PKCS #10 Certificate Signing
   Requests (CSRs).  The embedded alternative cryptographic materials
   allow a Public Key Infrastructure (PKI) to use multiple cryptographic
   algorithms in a single object, and allow it to transition to the new
   cryptographic algorithms while maintaining backwards compatibility
   with systems using the existing algorithms.  Three X.509 extensions
   and three PKCS #10 attributes are defined, and the signing and
   verification procedures for the alternative cryptographic material
   contained in the extensions and attributes are detailed.
