| 摘 要： | 基于互认证和量子超密编码思想,提出了一种改进型量子直接通信协议.该协议由量子态分发过程和直接通信过程2部分组成,前者的主要目的是实现分发者Trent与用户之间的相互认证,并让2个合法用户(Alice和Bob)共享Bell态;后者将进行Alice与Bob的量子直接通信,以实现两者的消息传递.为了抵抗Eve窃听并同时进行相互身份认证,引入了一种诱骗光子检测方法.与其他同类型协议相比,本协议的量子态分发过程显得更加简单和实用,并且协议本身也更加高效,总效率接近100%.安全分析表明,该协议可有效抵抗窃听攻击、伪装攻击及一些特殊的Trent攻击,包括采用不同初始态的Trent攻击.

| Abstract: | Based on mutual authentication and dense coding,a novel revised efficient quantum direct communication scheme is proposed.It is composed of two phases：the quantum state distribution process and the direct communication process.The purpose of the former is to authenticate Trent and users to each other,and let the two legitimate users（Alice and Bob）safely share the Bell states.While the latter aims to make direct communication to transmit a secret message between Alice and Bob.In order to prevent from Eve＇s eavesdropping as well as to authenticate each other simultaneously,a decoy photon checking technique is applied.Compared with other analogous protocols,the quantum state distribution process is more simple and feasible and the proposed scheme is more efficient;i.e.,the total efficiency is almost 100%.Security analysis shows that the proposed scheme is secure against the eavesdropping attacks,the impersonation attacks,and some special Trent＇s attacks,including the attacks by using different initial states. |
