In an implementation of the ElGamal cryptosystem, is it acceptable to always
use the same prime and generator for every transmission? Or should a new
prime/generator pair be chosen for each communication?
Also does anyone know of where I can find suitable parameters to test the
system with ?
Does anyone know if any research has been done into the use of cellular
automata as one way functions? or even into the reversing of CAs?

cryptographic purposes, never too successfully. --Perry]
