New ASN.1 Modules for Cryptographic Message Syntax (CMS) and S/MIME
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.

RFC 5911 New ASN.1 for CMS and S/MIME June 2010 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 [RFC5912] can stand on their own and do not need to import definitions from anywhere else. Also note that the ASN.1 modules in this document have references in their text comments that need to be looked up in original RFCs, and that some of those references may have already been superseded by later RFCs. The document also includes a module of common definitions called "AlgorithmInformation". These definitions are used here and in [RFC5912]. Hoffman & Schaad Informational [Page 3]
RFC 5911 New ASN.1 for CMS and S/MIME June 2010 Note that some of the modules here import definitions from the common definitions module, "PKIX-CommonTypes", in [RFC5912]. 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 the 1988 ASN.1 syntax had ANY holes to allow for variable syntax now use 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 types of algorithms are defined. A single consistent name for each different algorithm type is used. For example, an object set named PublicKeys contains the public keys defined in that module. If no public keys are defined, then the object set is not created. When importing these object sets into an ASN.1 module, one needs to be able to distinguish between the different object sets with the same name. 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 } 2. ASN.1 Module AlgorithmInformation This section contains a module that is imported by many other modules in this document. Note that this module is also given in [RFC5912]. This module does not come from any existing RFC.
