The latter part of my mini-prediction is becoming reality. See , a new Java-based attack being mounted on RC5-64.
Besides using Java, they make the further simplification of discarding
the keyserver! Instead the client simply chooses random blocks, and
by probability theory (which I should have thought through myself but
didn't) the expected time to solution is twice that when a keyserver
is employed. Under Netscape 3, the Java client runs at about 1/250
the speed of the Bovine clients which use assembler portions tuned for
each architecture; I would expect JIT to narrow the gap to within a
factor of 10.
