Quantum Zero Knowledge Proof in a Group

Abstract

Zero knowledge protocol is a basic method of cryptography,which means that the certifier owns a secret,and it doesn′t reveal any other useful information about the secret to verifier when authenticated.The advantage is to keep its identity recognized without being substituted and useful information not revealed.However,the presently known typical zero knowledge proof is based on computing complexity.According to the basic thought of classical zero knowledge protocol,a scheme for quantum zero knowledge protocol in a group using a mode of quantum secure communication is designed.
