Network Working Group R. Housley Internet-Draft Vigil Security Intended status: Informational C. Wallace Expires: 22 December 2021 Red Hound Software 20 June 2021 New ASN.1 Modules for the Evidence Record Syntax (ERS) draft-housley-ers-asn1-modules-02 Abstract The Evidence Record Syntax (ERS) and the conventions for including these evidence record in the Server-based Certificate Validation Protocol (SCVP) are expressed using ASN.1. This document offers alternate ASN.1 modules that conform to the 2002 version of ASN.1 and employ the conventions adopted in RFC 5911, RFC 5912, and RFC 6268. There are no bits-on-the-wire changes to any of the formats; this is simply a change to the ASN.1 syntax. Status of This Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF).

Introduction Some developers would like the IETF to use the latest version of ASN.1 in its standards. This document provides alternate ASN.1 modules to assist in that goal. The Evidence Record Syntax (ERS) [RFC4998] provides two ASN.1 modules, one using the 1988 syntax [OLD-ASN1], which has been deprecated by the ITU-T, and another one using the 2002 syntax [NEW-ASN1], which continued to be maintained and enhanced. This document provides an alternate ASN.1 module that follows the conventions established in [RFC5911], [RFC5912], and [RFC6268]. In addition, [RFC5276] specifies the mechanism for conveying Evidence Records in the Server-based Certificate Validation Protocol (SCVP) [RFC5055]. There is only one ASN.1 module in [RFC5276], and it uses the 1988 syntax [OLD-ASN1]. This document provides an alternate ASN.1 module using the 2002 syntax [NEW-ASN1] and follows the conventions established in [RFC5911], [RFC5912], and [RFC6268]. Note that [RFC5912] already includes an alternate ASN.1 module for SCVP [RFC5055]. The original ASN.1 modules get some of their definitions from places outside the RFC series. Some of the referenced definitions are somewhat difficult to find. The alternate ASN.1 modules offered in this document stand on their own when combined with the modules in [RFC5911], [RFC5912], and [RFC6268]. Housley & Wallace Expires 22 December 2021 [Page 2] Internet-Draft New ASN.1 Modules for the ERS June 2021 The alternate ASN.1 modules produce the same bits-on-the wire as the original ones. The alternate ASN.1 modules are informative; the original ones are normative. 2.

IANA Considerations IANA is requested to assign two object identifiers from the "SMI Security for LTANS Module Identifier" registry to identify the two ASN.1 modules in this document. The assignment of these object identifiers is requested: 1.3.6.1.5.5.11.0.1.2 id-mod-ers-v2 [ThisRFC] 1.3.6.1.5.5.11.0.5.2 id-mod-ers-scvp-v2 [ThisRFC] Housley & Wallace Expires 22 December 2021 [Page 6] Internet-Draft New ASN.1 Modules for the ERS June 2021 5. Security Considerations Please see the security considerations in [RFC4998] and [RFC5276]. This document makes no changes to the security considerations in those documents. The ASN.1 modules in this document preserve bits- on-the-wire as the ASN.1 modules that they replace. 6. References 6.1.
