The baseline 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 requests. It does so by defining a
SIP header field for conveying a signature used for validating the
identity and for conveying a reference to the credentials of the
signer.
This document obsoletes RFC 4474.
This document is a product of the Secure Telephone Identity Revisited Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
