The MOR cryptoystem and special linear groups over finite fields

The ElGamal cryptosystem is in the heart of public key cryptography. It is known that the MOR cryptosysetm generalizes it from the cyclic group to the
automorphism group of a (non-abelian) group. I will start by describing the MOR cryptosystem and then we will use the special linear group over a finite field as the platform group. It seems likely that this project is competitive with the elliptic curves over finite fields in terms of security. I'll explain why I think so. Then we can talk about challenges in implementation of this cryptosystem.
