The IESG has approved the following document:
- 'DTLS Tunnel between a Media Distributor and Key Distributor to
   Facilitate Key Exchange'
  (draft-ietf-perc-dtls-tunnel-12.txt) as Informational RFC

This document is the product of the Privacy Enhanced RTP Conferencing Working
Group.

The IESG contact persons are Murray Kucherawy and Francesca Palombini.

Technical Summary

   This document defines a DTLS tunneling protocol for use in multimedia
   conferences that enables a Media Distributor to facilitate key
   exchange between an endpoint in a conference and the Key Distributor.
   The protocol is designed to ensure that the keying material used for
   hop-by-hop encryption and authentication is accessible to the Media
   Distributor, while the keying material used for end-to-end encryption
   and authentication is inaccessible to the Media Distributor.

Working Group Summary

This document has been discussed and reviewed several times by the
WG. Given the nature of work proposed by this document as defining 
one of the ways to setup protocol machinery between 
a key distributor and the end points for providing keying material 
needed for PERC double encryption procedures,  there was a general
consensus to move forward with this document in the WG.

Document Quality

An earlier version of the draft was implemented along with 
PERC double and EKT implementations to realize the protocol 
workings for end to end encryption.

No expert reviews have been solicited beyond the usual ones triggered by Last Call.

Personnel

The document shepherd is Suhas Nandakumar; the responsible Area Director is Murray S. Kucherawy.
