The guy who wrote the Duke press release didn't even know about
Deep Crack, as it happens.
Nonetheless, this was a story that reportedly played big in Europe,
India, Africa, and Japan because they are still saddled with 40-bit
American crypto in many of their installed business apps.
For them, the story was that one machine -- not the couple hundred
Ian used -- was repeatedly popping 40-bit crypto with a averge brute force
attack of 3.75 hr.
Makes one think that maybe EFF should maybe set a benchmark -- your
15 seconds would be nice -- for how long on average it takes Deep Crack to
brute force 40-bit ciphers. (I'll copy this to John G. for him to
consider, next time he winds up the rubber band and exercises the EFF's
Cracker.)
Suerte,
