From: Thomas Grant Edwards <tedwards@src.umd.edu> I am thinking of the use of a trusted adjudicator who could receive information from both the original participants and check to see if the two keys matched. How do you authenticate the adjudicator? You'll have to communicate with the adjudicator and verify one of their signatures. You can just as easily exchange signed DH parameters directly with the other party and verify the signature of your correspondent. This is another one of those problems where potential solutions often just lead to infinite regress. Eric
