Vincent Follow up question regarding your general comments on sect 8.1 and 8.2 which we have not yet addressed in -09 ; > Attacks of section 8.1 seems more realistic to me than attacks of section 8.2 > because of a weaker attacker model: the attacker is outside of the systems, > and not necessarily on the path. > Therefore I would have liked to see more details in section 8.1, that’s all. You're asking for greater detail in sect 8.1 precisely because you estimate that third-party attacks (aka outsiders to a given conference) are more likely/common than the attacks we covered in the subsequent 8.2 section. Is that correct? If so, I think we could restate some of what we have in sect 8.1 to make it flow better and/or be clearer. But it is not clear to us what we left out detail-wise, or if we left out other attack examples. With PERC's HBH integrity checks, authentication as well as HBH and E2E encryption, we can quickly describe in text the prevention/mitigation of attacks on the confidentiality of the media/content - PERCs reason to be - to explain some of the brevity. Could you help point us in the right direction with an example or two of the things we should do to detail/elaborate sect 8.1. > ** General comments about 8.1 and 8.2 > Insider attacks are a powerful form of attacker model with severe consequences. > This is not a big surprise.
