Abstract

   The 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.

Internet-Draft             New ASN.1 for PKIX              November 2007


1.  Introduction

   Some developers would like the IETF to use the latest version of
   ASN.1 in its standards.  Most of the RFCs that relate to security
   protocols still use ASN.1 from the 1988 standard, which has been
   deprecated.  This is particularly true for the standards that relate
   to PKIX, CMS, and S/MIME.

   This document updates the following RFCs to use ASN.1 modules that
   conform to the 2002 version of ASN.1 [ASN1-2002].  Note that not all
   the modules are updated; some are included to simply make the set
   compete.

   o  RFC 2560, PKIX Online Certificate Status Protocol (OCSP) [RFC2560]

   o  RFC 2986, PKCS #10 certificate request [RFC2986]

   o  RFC 3279, PKIX algorithms and identifier [RFC3279]

   o  RFC 3280, PKIX certificate and CRL profile [RFC3280] (both the
      implicit and explicit modules)

   o  RFC 3281, PKIX attribute certificates, version 2 [RFC3281]

   o  RFC 3852, contains PKIX attribute certificates, version 1
      [RFC3852]

   o  RFC 4210, PKIX CMP (Certificate Management Protocol) [RFC4210]

   o  RFC 4211, PKIX CRMF (Certificate Request Message Format) [RFC4211]

   o  RFC-to-be, PKIX SCVP (Server-based Certificate Validation
      Protocol) [SCVP]

   Note that some of the modules in this document get some of their
   definitions from places different than the modules in the original
   RFCs.  The idea is that these modules, when combined with the modules
   in [NEW-CMS-SMIME] can stand on their own and do not need to import
   definitions from anywhere else.

1.1.  Issues

   This section will be removed before final publication.

1.1.1.  More Modules To Be Added

   There are many modules from standards-track RFCs that are not listed
   in this document or the companion document on CMS and S/MIME.  We



Hoffman & Schaad          Expires May 11, 2008                  [Page 3]

Internet-Draft             New ASN.1 for PKIX              November 2007


   will discuss with the two communities which modules are appropriate
   for the two documents.  We will also consider making "super-modules",
   individual modules which might update multiple RFCs at one time.  We
   may also add objects to some of the modules.

1.1.2.  Algorithm Structure

   Algorithms are currently not defined here.  We need to discuss what
   structure we want for algorithm objects.  Currently, we just do
   "parameter, OID", but we could add more.  Because we don't know what
   the final structure is, the object sets in the various modules are
   commented out.  We will fix this before finishing this project.

1.1.3.  Module OIDs Changing

   The OIDs given in the modules in this version of the document are the
   same as the OIDs from the original modules, even though some of the
   modules have changed syntax.  That is clearly incorrect.  In a later
   version of this document, we will change the OIDs for every changed
   module.

12.  Security Considerations

   Even though all the RFCs in this document are security-related, the
   document itself does not have any security considerations.  The ASN.1
   modules keep the same bits-on-the-wire as the modules that they
   replace.
