Key Management Extensions for Session Description Protocol and Real Time Streaming Protocol
RFC 4567, “Key Management Extensions for Session Description Protocol and Real Time Streaming Protocol”, is a Proposed Standard document published in July 2006 by J. Arkko, F. Lindholm, M. Naslund, K. Norrman, E. Carrara. The canonical text is published by the RFC Editor.
Abstract
This document defines general extensions for Session Description Protocol (SDP) and Real Time Streaming Protocol (RTSP) to carry messages, as specified by a key management protocol, in order to secure the media. These extensions are presented as a framework, to be used by one or more key management protocols. As such, their use is meaningful only when complemented by an appropriate key management protocol.
General guidelines are also given on how the framework should be used together with SIP and RTSP. The usage with the Multimedia Internet KEYing (MIKEY) key management protocol is also defined. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
