摘　　要：借助测量设备无关量子密钥分配协议的安全性,提出了测量设备无关的量子身份认证协议。在此协议下,认证中心和认证方以共享密钥加密认证信息和认证密钥,将其发送至第三方进行贝尔态测量以提取安全的认证信息,实现认证中心对认证方有效认证,并更新共享密钥。分析协议性能显示,系统在不同攻击下认证过程是安全且有效的。Utilized to security properties of measurement-device-independent quantum key distribution （MDI-QKD） protocol, quantum identity authentication scheme based on MDI （QIA-MDI） protocol was presented. In this protocol, authentication center （AC） and authentication user have encrypted authentication information and next authenticated key by shared key, and then they transmitted the encrypted information to untrusted third party for Bell-state measurement （BSM）. The secret authentication information was obtained through the BSM result, which can verify the communicator identity and update shared key. The security performance of the proposed scheme is extensively analyzed and accordingly confirmed in the case of attacks.
