Hi Éric, For some reason, your Block didn't get sent to the relevant mailing lists, so I'm crafting my own reply :) - 'Selection among multiple encryption keys' should there be a way to use > different encryption algorithm as well with the encapsulation (I noted that > this bullet is explicitly for inside a session)? > No. The assumption is that the algorithm is fixed for a given flow, but there may be multiple keys (e.g., for different senders), and of course, each encrypted unit needs a different nonce. We could add some text to clarify this if you think it's really necessary, but this seems like a finer level of granularity than is needed in a charter. > - like Magnus, I find "Information to form a unique nonce" pretty vague > and is it 'nonce' or more 'initialization vector' ? > I've revised to be clear that the encapsulation has a standard nonce formation algorithm, and the wire format provides the input to it. The word "nonce" is standard here (see https://tools.ietf.org/html/rfc5116#section-2.1) > - 'This working group will not specify the signaling required to configure > SFrame encryption", it is unclear to me whether the WG will specify a > control channel to negotiate keys and crypto algorithms as the current > sentence appears more generic configuration (e.g., supported crypto > algorithms) > No, the WG will not specify a control channel. That is something the application will have to provide. > - only one milestone ? There is nothing about the RTP mapping document > that is mentioned in the charter text > Yep. Just one thing, the encapsulation. The MLS mapping and RTP considerations should both be small enough to be sections in that document. --Richard
