So let's call this a "password-based" key exchange ;) Confusion's key exchanges *and* messages are brokered by a high-latency mixer service such that the either appears to be a ciphertext of the same length, with the goal of "laundering" key exchanges through other traffic. Arguably with a point encoding format like Elligator we could do a ZRTP-style exchange this way and uses SAS-strings to authenticate a D-H exchange, the handshake messages still appearing indistinguishable from ciphertexts to an outside observer. Perhaps that would be a better approach... -- Tony Arcieri
