-A new signature scheme is proposed, together with an imple- mentation of the Diffie-Hellman key distribution scheme that achieves a public key cryptosystem. The security of both systems relies on the difficulty of computing discrete logarithms over finite fields. 

A public-key cryptosystem based on second order linear sequences
