Hi, we submitted a draft discussing a potential use case for SIP Identiy targeting a Best Current Practice approach. The draft basically describes the usage of SIP identity to enable the protected submission of certificate material within a SIP request to a remote UA. The certificate material may belong to the user or to the device and may be short or long term. Using SIP Identity enables the receiver to assocciate the received certificate material with the authenticated identity and use it e.g. for a secure negotiation of further security parameter. Possible use cases comprise environments were no globally resolvable certificates are provided or were the certificate material available on the device may not be directly associated with the user of that device. The former version of the draft has been submitted and discussed within the SIPPING WG, but it was stated that this is rather a SIP topic. So we updated the draft and submitted this as initial version to the SIP WG. We would like to see if there is sufficient interest to bring this approach forward in the SIP WG.

Title : SIP Identity Usage Author(s) : S. Fries, et al. Filename : draft-fries-sip-identity-usage-bcp-00.txt Pages : 11 Date : 2006-10-17 This document describes a use case for the SIP Identity document involving certificate, which may not be publically resolvable. It provides a best current practice document for binding an identity to a certificate for the duration of a session. The certificate may then be used to bootstrap further security parameters, e.g., for securing media data. A discussion of possible enhancements is included in the appendix. Editors Note: The first version of this draft was discussed in the SIPPING WG. As the target of this draft is a BCP for current issues, the draft was updated and submitted to the SIP WG.

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.
