FYI, We will use the PERC list from here on for this type of discussion. Cheers Magnus

Sep 2016 Submit architecture or framework specification to IESG (Standards Track) Jan 2017 Submit documentation of how to integrate solution in SIP, WebRTC and CLUE to IESG (Informational) Jun 2017 Submit SRTP protocol extension specification to IESG (Standards Track) Jun 2017 Submit Key-management protocol specification to IESG (Standards Track) I know people see this as quite urgent, but we actually appear to have quite a lot to discuss on how it should work and be solved. Then we must show due dillegence in getting the pieces well specified and well reviewed and tested. Thus, I think 2 years is not at all uncalled for, unfortunately. > > 2) Do you want to add anything based on Stephen's last email (quoted > below): > >> BTW - just to clarify in case it's useful - I interpret >> the name of this WG and the charter to be implicitly >> saying that the goal is to minimise the amount of data >> (whether metadata or not) that is meaningful to the >> media distribution device.

I would propose that we enter into the WG objectives the following sentence: The meta information provided to the central device is to be limited to the minimal required for it to perform its function to preserve the conference participants' privacy. The full paragraph would then read: WG Objectives This WG will work on a solution that enables centralized SRTP-based conferencing, where the central device distributing the media is not required to be trusted with the keys to decrypt the participants’ media. The media must be kept confidential and authenticated between an originating endpoint and the explicitly allowed receiving endpoints or other devices. The meta information provided to the central device is to be limited to the minimal required for it to perform its function to preserve the conference participants privacy. Further, it is desired that a solution still provides replay protection, so that the media distribution devices can’t replay previous parts of the media. Opinions on that. Please respond quickly.
