I went to http://www.cryptography.com/timingattack.html and found the whole thing to be totally incomprehensible from a layman's point of view. I apologize for having not read "Applied Cryptography", which might have made the abstract a simpler read - but even if I had I'd have been baffled by a lot of the terminology and equations in this paper. Can anyone post a brief summary which explains the essential workings of the attack? I'd be very grateful. --giles ===========================>>>http://pages.ripco.com/~gibo as long as I shall stay alive I never want a nine to five -----BEGIN PBP SIGNATURE----- Version: 1.0.0, Copyright 1995, Pretty Bad Privacy Giles Bowkett gibo@ripco.com I am who I am because I say so.
