IETF RFC 4568
Session Description Protocol (SDP) Security Descriptions for Media Streams
Organization: | IETF |
Publication Date: | 1 July 2006 |
Status: | active |
Page Count: | 44 |
scope:
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.
