Well, I'm going to be contrarian here. I'm not convinced that this is
needed.
I think certificate based authentication is a great idea. However, I am
not sure I understand why TLS is not an appropriate solution.

Describes a set of requirements for:
This document defines requirements for adding certificate
authentication to the Session Initiation Protocol (SIP). This
document is being presented with the intention of providing clear
requirements to any potential solutions specifying certificate
authentication within SIP networks. Supporting certificate
authentication in SIP would provide strong authentication and
increase the types of possible deployment scenarios.
(Before we go any further, please forget all about the solutions
document - that comes later and we are not dealing with it now)
We need to decide whether there is support for a body of work in this
area, and therefore whether we should charter some requirements work in
the SIP WG.
(Because this is security related we have agreed that SIP does the
requirements drafting and not SIPPING)
So can I hear opinions of the WG on:
- whether this represents a problem space that the working group
should draft requirements on?
- whether the problem space exists but is something slightly
different, and if so what is that problem space?
- whether there is a more general problem that the security area
should be addressing, rather than the SIP group addressing something
specific?
- based on your answers to the first three questions, whether this
draft is essentially in the right direction to be adopted as the WG
draft assuming we create the charter item, or whether we need to seek
some other input draft?
- and finally, whether (assuming we go ahead with this work) there
is any work in any other IETF WG that we should take account of?

Keith
