   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

Internet-Draft        New ASN.1 for CMS and S/MIME             July 2008


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
   complete.

   o  RFC 3370, CMS Algorithms [RFC3370]

   o  RFC 3565, Use of AES in CMS [RFC3565]

   o  RFC 3851, S/MIME Version 3.1 Message Specification [RFC3851]

   o  RFC 3852, CMS main [RFC3852]

   o  RFC 4108, Using CMS to Protect Firmware Packages [RFC4108]

   o  RFC 4998, Evidence Record Syntax (ERS) [RFC4998]

   o  RFC 5035, Enhanced Security Services (ESS) [RFC5035]

   o  RFC 5083, CMS Authenticated-Enveloped-Data Content Type [RFC5083]

   o  RFC 5084, Using AES-CCM and AES-GCM Authenticated Encryption in
      CMS [RFC5084]

   o  RFC 5275, CMS Symmetric Key Management and Distribution [RFC5275]

   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-PKIX] can stand on their own and do not need to import
   definitions from anywhere else.

   The document also includes a module of common defintions called
   "AlgorithmInformation".  These definitions are used here and in
   [NEW-PKIX].

   Note that some of the modules here import definitions from the common
   definitions module, "PKIX-CommonTypes", in [NEW-PKIX].

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 PKIX.  We 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.


2.  ASN.1 Module AlgorithmInformation

   This section contains a module that is imported by many other modules
   in this document and in [NEW-PKIX].  This module does not come from
   any existing RFC.

   AlgorithmInformation
       {iso(1) identified-organization(3) dod(6) internet(1) security(5)
       mechanisms(5) pkix(7) id-mod(0) id-mod-algorithInformation(99)}

   DEFINITIONS ::=
   BEGIN

   EXPORTS ALL;
   IMPORTS ;

  --  Create the object sets for each of the different type of signature

  --
  --  Philosophy:  Sean Turner raised the question about wheither theses
  --  object sets should be defined as being extensible.  My response is
  --  as follows:
  --
  --  If the working group believes that this document would be updated
  --    in the future for the definition of new algorithms, or that
  --    this document would be updated to reference (and thus include)
  --    new algorithms defined in other documents, then these object
  --    sets need to be marked as extensible.
  --  If the working group believes that new algorithms will be defined
  --     by the creation of new documents, then these object sets do not
  --     need to be extensible.
  --  In either case, documents that are referencing these objects sets

6.  ASN.1 Module for RFC 3852

   This module has an ASN.1 idiom for noting in which version of CMS
   changes were made from the original PKCS #10; that idiom is "[[v:",
   where "v" is an integer.  For example:

   RevocationInfoChoice ::= CHOICE {
       crl CertificateList,
       ...,
       [[5: other [1] IMPLICIT OtherRevocationInfoFormat ]] }

   Similarly, this module adds the ASN.1 idiom for extensiblity (the
   "...,") in all places that have been extended in the past.  See the
   example above.

13.  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.

Internet-Draft        New ASN.1 for CMS and S/MIME             July 2008


A.1.  Changes between draft-hoffman-cms-new-asn1-00 and
      draft-ietf-smime-new-asn1-00

   Changed the draft name.

   Added RFC 3565,

   Added RFC 4998.

   Made RFCs-to-be 5083 and 5084 into RFCs.

   In RFC 3370, a line in the comment staring with "Another way to
   do..." was not commented out when it should have been.

   In RFC 3851, the name of the module from which we are importing was
   wrong, although the OID was right.

   In RFC 3852, added the "...," and "[[v:" ASN.1 idioms to indicate
   which version of CMS added the various extensions.

A.2.  Changes between draft-ietf-smime-new-asn1-00 and -01

   Added RFC 5275.

   Added module for algorithm classes, and modified RFC 3370 and RFC
   3852 to uses the classes defined.
