<abstract>
<t>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]</t></abstract></front>
