The IESG has approved the following document: - 'Certificate Management Service for The Session Initiation Protocol (SIP)' <draft-ietf-sip-certs-15.txt> as a Proposed Standard This document is the product of the Session Initiation Protocol Working Group. The IESG contact persons are Robert Sparks and Gonzalo Camarillo. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-sip-certs/ Technical Summary This draft defines a Credential Service that allows Session Initiation Protocol (SIP) User Agents (UAs) to use a SIP event package to discover the certificates of other users. This mechanism allows user agents that want to contact a given Address-of-Record (AOR) to retrieve that AOR's certificate by subscribing to the Credential Service, which returns an authenticated response containing that certificate. The Credential Service also allows users to store and retrieve their own certificates and private keys. Several operational modes are defined, wherein the credential service may act only as a distributor of the public key, may also act as a distributor of the encrypted private key, or as the repository and distributor of both the public and private key. Working Group Summary The working group process for this draft was unusually long, spanning several years. Document Quality We are currently not aware of any publicly announced implementations of this specification, although one can be built relatively trivially on top of general purpose SIP Events servers, and we are aware of at least one internal prototype implemented in this manner. MIME type review was non-controversial and was initiated on March 12, 2007. Björn Höhrmann raised several points, which were resolved in the -04 version of this specification. SIP Events review was performed by Adam Roach, with several issues being noted and resolved in -03 of this specification. Personnel Dean Willis is Proto Document Shepherd for this document. Robert Sparks is the shepherding AD. Jon Peterson was the previous shepherding AD.
