RFC 3261 introduces the concept of adding an S/MIME body to a Session
Initiation Protocol (SIP) request or response in order to provide
reference integrity over its headers.  This document provides a more
specific mechanism to derive integrity and authentication properties
from an 'authenticated identity body', a digitally-signed SIP
message, or message fragment.  A standard format for such bodies
(known as Authenticated Identity Bodies, or AIBs) is given in this
document.  Some considerations for the processing of AIBs by
recipients of SIP messages with such bodies are also given.

This document is a product of the Session Initiation Protocol Working
Group of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
