摘要:

利用连续两次量子隐形传态技术,提出了基于四粒子团簇态的跨中心量子网络身份认证方案,实现了分布式量子通信网络中对客户的身份认证。在该方案中,认证系统包括主服务器和客户端服务器,主服务器和客户端服务器之间通过共享四粒子团簇态为量子信道进行通信,客户所有的操作都在客户端服务器上进行,不直接与主服务器进行通信。身份认证全部由服务器根据量子力学原理进行,保证了认证方案的安全性。最后,对该方案进行了安全性分析。

Abstract:

Using the two times quantum teleportation, a quantum identification scheme of cross-center based on four-qubit cluster state is proposed, and the identification for user in distributed network is realized. In this scheme, the identification system consists of main server and client server, and the communication between main server and client server is performed using the four-qubit cluster state as quantum channel. All the operations of any user are processed at client server and there is no direct communication between user and main server. All authentications are processed by servers based on the principles of quantum mechanics, and its security is guaranteed by quantum mechanism. Finally, the security of the quamtum identification scheme is analysed.

Key words: quantum optics, quantum communication, quantum identification, quantum teleportation, cluster state
