Last Call Review of draft-ietf-payload-rtp-klv-
review-ietf-payload-rtp-klv-secdir-lc-melnikov-2012-02-08-00

I have reviewed this document as part of the security directorate's 


ongoing effort to review all IETF documents being processed by the IESG. 


 These comments were written primarily for the benefit of the security 


area directors.  Document editors and WG chairs should treat these 


comments just like any other last call comments.






This document specifies the payload format (and the corresponding media 


type) for packetization of KLV (Key-Length-Value) Encoded Data, as 


defined by the Society of Motion Picture and Television Engineers 


(SMPTE) in SMPTE 336M, into the Real-time Transport Protocol (RTP).






The document is well written. Its Security Considerations section talks 


about several ways of providing RTP payload confidentiality, integrity 


and source authenticity. It also talks about causing denial of service 


in naive decoders by specially crafted packets. I can't think of other 


things that needs to be covered in this section.
