基于量子隐形传态的无线通信网络身份认证方案*

摘要

提出了有中心的结构化量子通信网络概念，并在经典认证基础之上，结合量子隐形传态技术实现了无线通信网络的身份认证。此认证方案通过对无线局域网的认证进行探讨进而推广至整个无线通信网络中。在无线局域网中，在已获得SK与EPR对的前提下， STA与AP两端通过量子信道进行信息传输，然后AP对手中的量子态进行幺正变换后将得到的信息与原先的备份信息进行保真度计算，从而判定是否认证成功。%A concept of infrastructure quantum communication network is proposed, and an identification scheme for wireless communication networks is realized by combining classical certification and quantum teleportation.This identification scheme is discussed through the wireless LAN authentication and extended to the entire wireless communication network. In the wireless local area network, the information is transmitted between STA and AP who obtained the SK and EPR pair via quantum channel. Then AP will obtain the information through unitary transformation and calculate the fidelity with the original backup information, so as to determine whether the identification is successful or not.
