Title : Response Authentication in Session Initiation Protocol
Author(s) : F. Cao
Filename : draft-cao-sip-response-auth-01.txt
Pages : 15
Date : 2006-1-10
This draft describes some extensions for enhancing SIP response
authentication. In the real-world SIP deployment, TLS may be not
available on some hops. Due to the lack of other response
authentication mechanisms in SIP, several kinds of security attacks
could be conducted on those hops through SIP response. This draft
suggests some approaches for complementary enhancement on SIP
response authentication. With the new per-hop response
authentication proposed in this draft, the security gaps on the hops
without TLS can be bridged.

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.
