The Secure Real-time Transport Protocol (SRTP) protects unicast and multicast RTP packets. Multicast receivers of SRTP session data therefore share an SRTP master key for message authentication and decryption. This document describes how to establish a shared, "group key" for an SRTP session using RFC 3547, the Group Domain of Interpretation (GDOI) and RFC 2408, the Internet Security Association and Key Management Protocol. This document extends GDOI for SRTP group key establishment.
