Technical Summary This document extends the Session Description Protocol (SDP) to provide a meansof tunneling a key management protocol. This key management protocol would in turn be leveraged to secure a media stream, most likely via sRTP. One such key management protocol envisioned for use with this mechanism is MIKEY. The overallmechanism is geared towards use with SIP and RTSP. Working Group Summary The advancement of this document was supported by the MMUSIC WG. It is one of two mechanisms being advanced by MMUSIC to fill the gap left by the "k=" line mechanism of SDP. While the WG could not achieve consensus on a single mechanism, it is hoped that deployment experience will clarify the respective applicability of these two approaches. Protocol Quality This document was reviewed for the IESG by Jon Peterson.
