This document provides an extension to the cryptographic attribute (RFC 4568) defined for Session Description Protocol (RFC 4566) to enhance end-to-end communication security, so that some scenarios, e.g., forking and re-targeting can especially benefit from the extension. The usage of the provided extension in Secure Real-time Transport Protocol (SRTP, RFC3711) is also defined in this document.
