Session Description Protocol Security Descriptions for Media Streams
RFC 4568, “Session Description Protocol Security Descriptions for Media Streams”, is a Proposed Standard document published in July 2006 by F. Andreasen, M. Baugher, D. Wing. The canonical text is published by the RFC Editor.
Abstract
This document defines a Session Description Protocol (SDP) cryptographic attribute for unicast media streams. The attribute describes a cryptographic key and other parameters that serve to configure security for a unicast media stream in either a single message or a roundtrip exchange. The attribute can be used with a variety of SDP media transports, and this document defines how to use it for the Secure Real-time Transport Protocol (SRTP) unicast media streams. The SDP crypto attribute requires the services of a data security protocol to secure the SDP message. [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.
