Title : Discussion of suitability: S/MIME instead of Digest
Authentication in the Session Initiation Protocol
(SIP)

Digest authentication (as defined in RFC2617) is used in SIP
(RFC3261) for user authentication, and less frequently for message
integrity of MIME bodies carried in SIP. Various members of the IETF
security community have periodically suggested that Digest should be
deprecated in favor of the SIP use of S/MIME (RFC2633), support for
which was recently introduced in RFC3261. The author seeks clarity
from the IETF security community on behalf of the SIP community about
the feasibility and possible benefits of using S/MIME instead of
Digest in one or both of these applications.

In the body type:
"FILE /internet-drafts/draft-mahy-sipping-smime-vs-digest-01.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.
