[net.math] duke.2754: Faster Algorithm for finding the Multiplicati

ccc (11/12/82)

There is a much faster method for finding the M. I. where p is prime.  It
involves using Euclid's alorithm and the so-called "magic box".  I can dig
up my old number theory notes and post the algorithm to the net if anyone's
interested...

I used the method in an implementation of a public-key cryptosystem a while
back, and for large (>75 digit) primes it was about 50 times faster than an
incremental search, and it gets better as the prime gets larger.
