The document, along with other ballot positions, can be found here: http://datatracker.ietf.org/doc/draft-ietf-core-groupcomm/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Sorry, I only had time to quickly scan this. - For a non MC IP addr, how does one know a URI is for a group? - 5.3.3: That draft-keoh draft is quite controversial in the DICE WG. The question there is whether or not its at all sensible to try do group security in the DTLS record layer. I think you really ought recognise that, since its quite possible that a very different solution will be needed in reality. - Thanks for 5.4! I think you should also note that even with encryption providing confidentiality, traffic analysis could be a powerful tool against CoAP and group communication, so future work with CoAP and developers/deployers should also take into account traffic analsyis. To use your fav example, its not hard to detect the lights being turned on or off even if that's done via ciphertext is it?
