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 December 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 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]
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. 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
Hoffman & Schaad Expires June 23, 2008 [Page 3]
Internet-Draft New ASN.1 for CMS and S/MIME December 2007
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.

5. 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.

11. 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.

[[ This entire section is to be removed upon publication. ]]
Hoffman & Schaad Expires June 23, 2008 [Page 37]
Internet-Draft New ASN.1 for CMS and S/MIME December 2007
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.
