Secret-Key Agreement by Public Discussion. Upper Bounds Consider the following general key agreement problem. Assume that Xxxxx, Xxx and Xxx know random variables X, Y and Z, respectively, with joint probability distribution PXY Z , and that Xxx has no information about X and Y other than through her knowledge of Z. More precisely, I(XY ; T jZ) = 0 where T summarizes Xxx's complete information about the universe. In this paper, X; Y and Z take on values in some nite alphabets X ; Y and Z, respectively. Xxxxx and Xxx share no secret key initially (other than possibly a short key required for guaranteeing authenticity and integrity of messages sent over the public channel), but are assumed to know PXY Z or at least an upper bound on the quality of Xxx's channel. In particular, the protocol and the codes used by Xxxxx and Xxx are known to Eve. Every message communicated between Xxxxx and Xxx can be intercepted by Xxx, but it is assumed that Xxx cannot insert fraudulent messages nor modify messages on this public channel without being detected. As mentioned before, attacks by Xxx other than passive wire-tapping can be detected when an unconditionally secure authentication scheme with a short initially shared secret key is used. If only a computationally secure authentication scheme were used, the unconditional security would only be retained against passive, but not against active wire-tapping.
