In this paper, a quantum identity authentication protocol is presented based on the counterfactual quantum key distribution system. Utilizing the proposed protocol, two participants can verify each other's identity through the counterfactual quantum communication system. The security of the protocol is proved against individual attacks. Furthermore, according to the characteristics of the counterfactual quantum key distribution system, we propose an authenticated counterfactual quantum key distribution protocol based on a novel strategy of mixing the two types of quantum cryptographic protocols randomly. The authenticated quantum key distribution can also be used to update the extent of the authentication keys.
本文提出了一种基于反事实量子密钥分发系统的量子身份认证协议。利用该协议，两个参与者可以通过反事实量子通信系统相互验证身份。证明了该协议在个体攻击下的安全性。此外，根据反事实量子密钥分发系统的特点，我们基于一种随机混合两种量子密码协议的新策略，提出了一种认证的反事实量子密钥分发协议。认证的量子密钥分发还可用于更新认证密钥的范围。
