The Huff curve–ElGamal graphic public key cryptosystem

Abstract

A new graph for the cryptographic application is presented in this work. This graph is defined using the Huff curve over a prime field. The Huffs curve graph (HCg) considered as an alternative graph of the Edwards curve graph (EdCG).The HCg is used to give another modified Version Public-key cryptosystem ElGamal (EPKC) the proposed HC-ElGamal graphic cryptosystem enhances the secure communication in compare with original EPKC.
