You know that most WebRTC does not use any SSRC in the signaling at all and the WebRTC security dose not change if the ssrc are signaled or not. Has it been analyzed? YES OF COURSE IT HAS - the whole of webrtc security drafts and security section of of the related WebRTC drafts are written based on the security being ssrc-less signaling.
