摘要/Abstract

摘要： 提出了一种基于量子纠缠态和非正交态的密钥分发及身份认证协议。其中纠缠态粒子用来分发密钥,非正交态粒子用来认证身份和检测量子信息有无被窃听。两者用“按密钥穿插”的方法混合在一起进行传输。由于非正交态粒子的双重作用,不但使得认证过程中不必传递经典信息,而且提高了密钥分发效率。另外此协议同时完成了密钥分发和身份认证,有效防止了以往所提出的协议中可能存在的假冒问题。

Abstract: A new protocol was proposed in which the quantum entangled states was used for quantum key distribution (QKD) and the quantum non-orthogonal states was used for user identification from eavesdropping as well. Both the two states were mixed as alternative form much or less in transmission via a quantum channel. Consequently, there was no need to transmit the classical information in identification process for dual contributions of non-orthogonal states. And the efficiency of QKD was got improved in the mean time. In addition, QKD and identification were completed simultaneously, so that the problem of impersonation was avoided.
