[AVT] Media over DTLS

Hi,

AVT working group members may be interested in the following suite
of drafts, which define a method for securing multimedia (especially)
RTP traffic using DTLS:

http://www.ietf.org/internet-drafts/draft-fischl-sipping-media-dtls-00.txt
http://www.ietf.org/internet-drafts/draft-tschofenig-avt-rtp-dtls-00.txt
http://www.ietf.org/internet-drafts/draft-fischl-mmusic-sdp-dtls-00.txt
http://www.ietf.org/internet-drafts/draft-modadugu-dtls-short-00.txt
http://www.ietf.org/internet-drafts/draft-rescorla-tls-partial-00.txt
http://www.ietf.org/internet-drafts/draft-ietf-tls-ctr-00.txt

Why is this interesting? SIP does not have a scheme for key negotiation
of media encryption that works with early media and forking. This set of
drafts addresses these issues. Instead of inventing a new key
negotiation protocol, it uses DTLS for key establishment and algorithm
negotiation while having the same on-the-wire packet format as SRTP.

HTML versions can be found at:

The draft of most interest to this WG is probably
draft-tschofenig-avt-rtp-dtls-00 but you may find it helpful to read
draft-fischl-sipping-media-dtls-00 first for background.
