-----BEGIN PGP SIGNED MESSAGE----- Tim May notes;
This is an important point, which I've seen mentioned a few times over the past 10 months, but not given nearly enough attention. To wit, if Clipjack phones are ever used by dissidents, subversives, Cypherpunks, etc., then the key block that goes out with every call--from both ends of course--will make recording the identities of both parties trivial.
I agree with Tim whole-heartedly on this one. If the NSA gets it's much desired "Digital Telephony Initiative" passed it will be a trivial matter both politically and technologicly to intercept and record all clipper key block transactions. The ability of the NSA to do this, and the usefullness of this kind of traffic analysis is left as an exercise for the reader.
