RFC 4474: Enhancements for Authenticated Identity Management in the Session Initiation Protocol (SIP)
This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 8224.
Current version: RFC 8224 — Authenticated Identity Management in the Session Initiation Protocol (SIP)
In plain English — editorial summary, not part of the RFC
The existing security mechanisms in the Session Initiation Protocol (SIP) are inadequate for cryptographically assuring the identity of the end users that originate SIP requests, especially in an interdomain context. This document defines a mechanism for securely identifying originators of SIP messages. It does so by defining two new SIP header fields, Identity, for conveying a signature used for validating the identity, and Identity-Info, for conveying a reference to the certificate of the signer.
