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]
