A new approach of elliptic curve Diffie-Hellman key exchange

Elliptic Curve Cryptosystem (ECC) schemes are public-key mechanisms that provide encryption, digital signature and key exchange capabilities. The advantage of elliptic curves is that they ensure a level of security equivalent to that of existing public key systems but with shorter key lengths. In this paper, we take an interest in public-key exchange of Diffie-Hellman. We propose a new approach of elliptic curve Diffie-Hellman key exchange.
