A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Session Initiation Proposal Investigation Working Group of the IETF.
Title : Requirements for End-to-middle Security for the Session Initiation Protocol (SIP)
Author(s) : K. Ono, S. Tachimoto
Filename : draft-ietf-sipping-e2m-sec-reqs-05.txt
Pages : 14
Date : 2004-12-9
A SIP User Agent (UA) does not always trust all intermediaries in its
request path to inspect its message bodies and/or headers contained
in its message. The UA might want to protect the message bodies and/
or headers from intermediaries except those that provide services
based on its content. This situation requires a mechanism called
'end-to-middle security' to secure information passed between the UA
and intermediaries, which does not interfere with end-to-end
security. This document defines a set of requirements for a mechanism
to achieve end-to-middle security.

In the body type:
"FILE /internet-drafts/draft-ietf-sipping-e2m-sec-reqs-05.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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
