Title : A Mechanism to Secure SIP Identity headers inserted by
Intermediaries

This draft defines a standard mechanism for securing SIP headers that
are inserted into requests and responses. The fundamental
requirements, for securing the headers inserted by an intermediary
routing or retargeting a request or response, are summarized. The
solution is directed towards headers that contain identity related
information, such as Record-Route, Via, and History-Info. The
proposed solution defines an Authenticated Inserted Identity Header
Body based on S/MIME to secure the headers. This mechanism is
optional, however, the use of it enhances the overall security of SIP
by ensuring the integrity of the inserted headers.

In the body type:
"FILE /internet-drafts/draft-barnes-sipping-sec-inserted-info-00.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
