People were doing this fourty years before Pratt's paper.
See, for example, Dick Lehmer's 1933 paper "Hunting Big Game
in the Theory of Numbers", where he describes proving primality
for a 19 digit divisor of 2^95+1.  It's on my web page at

http://www.cs.arizona.edu/~rcs/biggame4

Or see Math. Comp. in the early 1970s for examples with more
depth in the recursions.

Peter Trei, show some respect.
Brian Gladman implemented all 15 AES candidate ciphers.
He knows the field.

moving Crypto?

2001-07-31 Thread Richard Schroeppel

It's time to consider moving the annual Crypto conference out of
Santa Barbara.  The obvious places are Vancouver, Toronto, or
Mexico.  I know zilch about these places as conference venues.
Could someone knowledgable summarize the relative merits?
