Internet Engineering Task Force (IETF) S. Santesson Request for Comments: 5816 3xA Security Updates: 3161 N. Pope Category: Standards Track Thales ISSN: 2070-1721 March 2010 ESSCertIDv2 Update for RFC 3161 Abstract This document updates RFC 3161. It allows the use of ESSCertIDv2, as defined in RFC 5035, to specify the hash of a signer certificate when the hash is calculated with a function other than the Secure Hash Algorithm (SHA-1). Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741. Information about the current status of this document, any errata, and how to provide feedback on it may be obtained at http://www.rfc-editor.org/info/rfc5816.

Introduction The time-stamping protocol defined in RFC 3161 [RFC3161] requires that the Cryptographic Message Syntax (CMS) SignedData [RFC5652], used to apply a digital signature on the time-stamp token, include a signed attribute that identifies the signer's certificate. This identifier only allows SHA-1 [SHA1] to be used as the hash algorithm to generate the identifier value. The mechanism used in [RFC3161] employed ESSCertID from RFC 2634 [ESS]. RFC 5035 [ESSV2] updated ESSCertID with ESSCertIDv2 to allow the use of any hash algorithm. The changes to RFC 3161 [RFC3161] defined in this document allow ESSCertIDv2 to be used to include an identifier of the signing certificate as defined in RFC 5035 [ESSV2]. 1.1.
