Technical Summary RFC3261 introduces the concept of adding an S/MIME body to a 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. An important usage of the Authenticated Identity Body is seen in conjunction with SIP's Referred-By mechanism. Working Group Summary The working group strongly supported the advancement of AIB. Protocol Quality There were review comments for this document during WG discussion. There were no dissenting comments during Working Group Last Call or IETF Last Call. The document was reviewed for the IESG by Eric Rescorla and Allison Mankin.
