Zero-Knowledge Proof Scheme of Identity Authentication Based on ElGamal Digital Signature

Jianzhong Zhang

Abstract

A zero-knowledge proof scheme of identity authentication based on ElGamal digital signature is proposed,across zero-knowledge proof and smart card technology,we authenticate the user's identity efficiently and secretly.The scheme is secure under the assumption of the intractability of logarithm problems and the random oracle model.
