Dean, I assume that you refer to the proposal to use SDES that is discussed in 3GPP. However, 3GPP does not focus on that approach. Other signaling path solutions are discussed in 3GPP that exclude all intermediaries from access to the key. Clearly, allowing lawful interception is a requirement for 3GPP, as is preventing "unlawful interception". The middlebox issue is NOT a pretense for allowing only weak solutions for 3GPP. My proposals concerning the framework draft wouldn't make DTLS-SRTP any weaker, right? And making DTLS-SRTP more adequate for 3GPP/TISPAN scenarios would be a good thing, wouldn't it?
