Ballot Text

Technical Summary

   While the Secure Real-time Transport Protocol (SRTP) provides
   confidentiality for the contents of a media packet, a significant
   amount of metadata is left unprotected, including RTP header
   extensions and contributing sources (CSRCs). While there have been
   previous attempts to protect this data, they have had limited
   deployment, due to complexity as well as technical limitations.

   This document defines Cryptex as a new mechanism that completely
   encrypts header extensions and CSRCs and uses simpler signaling with
   the goal of facilitating deployment.

Working Group Summary

   Working group handling was uncontroversial once the document was adopted.
   In general, the discussions converged rapidly and there were no 
   long-standing disagreements.

Document Quality

   By IETF 111 (draft -02), test vectors and two implementations
   (libsrtp and jitsi-srtp) existed.

   There appear to be no concerns about document quality.

Personnel

   Bernard Aboba is the Document Shepherd.
   Murray Kucherawy is the responsible Area Director.
