8. Security Considerations

When using the secure RTP protocol (RTP/SAVP) [RFC3711], or the secure variant of the feedback profile (RTP/SAVPF) [RFC5124], the cryptographic context of a compound secure RTCP packet is the SSRC of the sender of the first RTCP (sub-)packet. This could matter in some cases, especially for keying mechanisms such as MIKEY [RFC3830] that allow use of per-SSRC keying.

Otherwise, the standard security considerations of RTP apply; sending multiple RTP streams from a single endpoint in a single RTP session does not appear to have different security consequences than sending the same number of RTP streams spread across different RTP sessions.
