To guarantee information security in communication, quantum identity authentication plays a key role in politics, economy, finance, daily life and other fields. In this paper, a new quantum multiparty simultaneous identity authentication protocol with Greenberger-Home-Zeilinger (GHZ) state is presented. In this protocol, the authenticator and the certified parties are the participants with quantum ability, whereas the third party is a classical participant. Here, the third-party is honest and the other two parties may be dishonest. With the help of a classical third-party, a quantum authenticator and the multiple certified parties can implement two-way identity authentication at the same time. It reduces the quantum burden of participants and lowers down the trustworthiness, which makes the protocol be feasible in practice. Through further security analysis, the protocol can effectively prevent an illegal dishonest participant from obtaining a legitimate identity. It shows that the protocol is against impersonation attack, intercept-measure-resend attack and entangle-measure attack, etc. In all, the paper provides positive efforts for the subsequent security identity authentication in quantum network.
为保证通信中的信息安全，量子身份认证在政治、经济、金融、日常生活等领域发挥着关键作用。本文提出了一种基于格林伯格-霍恩-泽林格（GHZ）态的新型量子多方同时身份认证协议。在该协议中，认证者和被认证方是具有量子能力的参与者，而第三方是经典参与者。在此，第三方是诚实的，另外两方可能不诚实。借助经典第三方，量子认证者和多个被认证方可以同时实现双向身份认证。它减轻了参与者的量子负担并降低了可信度，这使得该协议在实践中可行。通过进一步的安全性分析，该协议可以有效防止非法不诚实参与者获取合法身份。结果表明，该协议能抵御冒充攻击、拦截测量重发攻击和纠缠测量攻击等。总之，本文为量子网络中后续的安全身份认证提供了积极的探索。
