I-D ACTION:draft-ietf-sip-authid-body-02.txt



A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Session Initiation Protocol Working Group of the IETF.

	Title		: SIP Authenticated Identity Body (AIB) Format
	Author(s)	: J. Peterson
	Filename	: draft-ietf-sip-authid-body-02.txt
	Pages		: 12
	Date		: 2003-7-2
	
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.

Send a message to:

In the body type:
	"FILE /internet-drafts/draft-ietf-sip-authid-body-02.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
