Abstract

The Secure Real-time Transport Protocol (SRTP) [RFC3711] is a profile of the Real-time Transport Protocol (RTP) [RFC3550], which can provide confidentiality, message authentication, and replay protection to the RTP traffic and to the control traffic for RTP, the Real-time Transport Control Protocol (RTCP). It is important to note that the outgoing SRTP packets from a single endpoint may be originating from several independent data sources.
