Internet-Draft        New ASN.1 for CMS and S/MIME          January 2009


Abstract

   The Cryptographic Message Syntax (CMS) 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 CMS and S/MIME          January 2009


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.  Design Notes

   The modules in this document use the object model available in the
   2002 ASN.1 documents to a great extent.  Objects for each of the
   different algorithm types are defined.  Also, all of the places where
   in the 1988 ASN.1 syntax had ANY holes to allow for variable syntax
   now have objects.

   Much like the way that the PKIX and S/MIME working groups use the
   prefix of id- for object identifiers, this document has also adopted
   a set of two, three, and four letter prefixes to allow for quick
   identification of the type of an object based on its name.  This
   allows, for example, the same back half of the name to be used for
   the different objects.  Thus, "id-sha1" is the object identifier,
   while "mda-sha1" is the message digest object for "sha1".

   One or more object sets for the different type of algorithms are
   defined.  A single consistent name for each of the different
   algorithm types is used.  For example, an object set named PublicKeys
   might contain the public keys defined in that module.  If no public
   keys are defined, then the object set is not created.  When
   referencing these objects sets when imported, one needs to be able to
   disambiguate between the different modules.  This is done by using
   both the module name (as specified in the IMPORT statement) and the
   object set name.  For example, in the module for RFC 5280:

   PublicKeys FROM PKIXAlgs-2008 { 1 3 6 1 5 5 7 0 995 }
   PublicKeys FROM PKIX1-PSS-OAEP-Algorithms { 1 3 6 1 5 5 7  33 }

   PublicKeyAlgorithms PUBLIC-KEY ::= { PKIXAlgs-2008.PublicKeys, ...,
       PKIX1-PSS-OAEP-Algorithms.PublicKeys }

1.2.  Issues

   This section will be removed before final publication.

1.2.1.  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.  The WG (hopefully in coordination with the PKIX WG) needs to
   determine how to do this and what the result will be.

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.

   --  S/MIME Capabilities
   --
   --  We have moved the SMIME-CAPS out of rfc3851.asn to here since it
   --  is used in the PKIX document RFC 4262 - Use of S/MIME Caps in
   --  certificate extension
   --
   --
   --  This class is used to represent an S/MIME capability.  S/MIME
   --  capabilities are used to represent what algorithm capabilities
   --  an individual has. The classic example was the content encryption
   --  algorithm RC2 where the algorithm id and the RC2 key lengths
   --  supported needed to be advertised, but the IV used is not fixed.
   --  Thus for RC2 we used
   --
   --  cap-RC2CBC SMIME-CAPS ::= {
   --      TYPE INTEGER ( 40 | 128 ) IDENTIFIED BY rc2-cbc }
   --
   --  where 40 and 128 represent the RC2 key length in number of bits.
   --
   --  Another example where infomation needs to be shown is for
   --  RSA-OAEP where only specific hash functions or mask generation
   --  functions are suppoted, but the saltLength is specified by the
   --  sender and not the recipient.  In this case one can either
   --  generate a number of different capability items are generated,
   --  or a new S/MIME capability type could  be generated where
   --  multiple hash functions could be specified.
   --
   --
   --  SMIME-CAP
   --
   --  This class is used to associate the type descibing capabilities
   --  with the object identifier.

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 #7; 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.

Appendix A.  Change History

   [[ This entire section is to be removed upon publication. ]]

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

   Changed the draft name.

   Added RFC 3565,




Hoffman & Schaad          Expires July 13, 2009                [Page 59]

Internet-Draft        New ASN.1 for CMS and S/MIME          January 2009


   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.

A.3.  Changes between draft-ietf-smime-new-asn1-01 and -02

   Added design notes.

   Removed issue on "Algorithm Structure" and issue on "More Modules To
   Be Added".

   Updated all modules to use objects more deeply.

   In section 6, changed "PKCS #10" to "PKCS #7" to reflect the actual
   module where the changes were made.
