Technical Summary

This memo discusses the problem of securing real-time multimedia sessions, and explains why the Real-time Transport Protocol (RTP), and the associated RTP Control Protocol (RTCP), do not mandate a single media security mechanism.  Guidelines for designers and reviewers of future RTP extensions are provided, to ensure that appropriate security mechanisms are mandated, and that any such mechanisms are specified in a manner that conforms with the RTP architecture.


Working Group Summary

This document was already in IESG review and there were concerns from the Security area suggesting that there will be also a document describing the security options. It came back to the AVTcore WG and there is also the security option document that complements this document.
It was reviewed by the WG members and the WG security experts and there are no issues from the WG that is worth noting.
 

Document Quality

This document is an informational document and I would like to mention that Dan Wing and Alan Johnston did a review and made helpful comments that helped with the quality of the document.
There are of course implementations of the media security solutions including SRTP with SDES and DTLS SRTO but this document is only explain why we do not mandate a single solution.
