Abstract:

Quantum key distribution is an important way of quantum communication. In order to improve the feasibility and security of quantum key distribution,a quantum key distribution protocol which can realize multi-party quantum identity authentication is proposed in this paper. At first, the modified circuit of GV95 is used to realize the mutual authentication between the distributor and the first participant. Then the participants conduct multi-party quantum identity authentication through unitary operation. In this process, the distributor will check whether there are forged users in the participants through random detection. Furthermore, the trusted design combiner ensures the correctness of the recovered secret key by using the homomorphism of Hash function. The security analysis shows that this protocol can resist not only external attacks which include identity forgery attack, intercept-resend attack and Trojan horse attack, but also internal attacks.

Key words: multi-party quantum authentication, quantum key distribution, mutual identity authentication
