摘要:

提出了基于纠缠交换的量子两方身份认证协议,并扩展到基于纠缠交换的量子多方身份认证协议. 协议中通信用户初始共享的纠缠粒子对用作认证密钥. 用户通过对事先共享的纠缠粒子对进行纠缠交换和经典通信,实现用户之间的身份认证. 另外对2种量子身份认证协议的安全性分别进行了分析.

关键词: 纠缠交换, 量子两方身份认证, 量子多方身份认证

Abstract:

A quantum two-party authentication protocol based on entanglement swapping is proposed. This protocol is extended to a multi-party authentication protocol. In the protocols, the previously shared entangled pairs by users act as the authentication keys. The authentication among the users are realized by performing entanglement swapping on the shared entangled particles and by performing the classical communication. The security of the protocols is discussed respectively.

Key words: entanglement swapping, quantum two-party authentication, quantum multi-party authentication
