Response:
Check your numbers. The distributed.net site has
extensive statistics. The current estimated rate
if they switched over to DES is around 66 Gk/sec,
which is about 165 times the rate of your
hypothetical chip.
Wiener has publised an update to his paper, utilizing
Moore's Law to speed up his chips by a factor of 4.
The next RSA Labs DES challenge starts on the
13th of July. If d.n manages to achieve the
above rate (and I think they will), they will
exhaust the keyspace in 12.6 days. This gives
them an excellent chance of finding the key
within the 10 days required for the $10k
prize, and a certainty of winning $5k, unless
someone else gets there first. To the best of
my knowledge, no one has publically announced
an effort which even approaches d.n's keyrate.
