Re: [stir] I-D Action: draft-ietf-sipcore-rejected-00.txt

Of interest to the STIR community, but please keep the discussion on the SIPCORE list.

Updated the Security Considerations section to reflect Tolga’s better articulation of the smurf attack and the vCard integrity / traceability attack. We don’t have a protocol method to address the vCard issue, but I will talk with the card people as there is a draft over there that is 30% of the solution.

Comments welcome.
