The issue is extremely complicated at the moment; there are 11 competing
proposals right now for ways to negotiate encryption keys for RTP.
Relevant documents include:

RFC 3830
RFC 3711
draft-ietf-mmusic-kmgmt-ext-15
draft-ietf-mmusic-sdescriptions-12
draft-ietf-msec-mikey-rsa-r-02
draft-ietf-msec-mikey-dhhmac-11
draft-ietf-msec-newtype-keyid-05
draft-mcgrew-srtp-ekt-00
draft-baugher-mmusic-sdp-dh-00
draft-zimmermann-avt-zrtp-01
draft-tschofenig-avt-rtp-dtls-00
draft-fischl-sipping-media-dtls-00
draft-fischl-mmusic-sdp-dtls-00
draft-rescorla-tls-partial-00
draft-modadugu-dtls-short-00
draft-lehtovirtya-srtp-rcc-00
draft-fries-msec-applicability-00
draft-wing-mmusic-sdes-early-media-00

Dan Wing did the work to put together this list. He has also done a very
good job analyzing the current situation. See:
