摘要: 摘 要:随着信息技术的快速发展,人们在享受信息技术带来便利的同时,也面临诸如信息窃取、网络攻击等网络安全威胁。当前,由于量子独有的特性能确保量子通信的绝对安全,于是人们在量子通信领域中打开了确保信息安全的新思路,特别是量子密钥分发协议的研究受到了人们的广泛关注。本文基于Bell态的纠缠特性,提出可以进行双向身份认证的量子密钥分发协议;相比于传统的量子密钥分发协议,该协议有零知识性,能进行双向身份认证,只进行一次量子序列传输,就能同时完成身份认证与密钥分发;通过分析,表明本文提出的量子密钥分发协议能抵御截获/重发攻击及中间人攻击等一系列攻击。

Abstract: Abstract:With the rapid development of information technology,people enjoy the convenience brought by information technology.However network users also confront network security threats such as theft,cyber attacks.Currently,the unique features of quantum can ensure the absolute safety of quantum communication, so researchers opened up new ideas to ensure information security in the field of quantum communication,especially in quantum key distribution field,which has been widespread concerned.Based on the properties of entangled Bell states,this paper proposes a quantum key distribution protocol with two-way identity authentication.Compared to conventional quantum key distribution protocol,this protocol has the characteristic of Zero-knowledge,and two-way identity authentication,as well as only once quantum sequence transmission which are capable of finishing identity authentication and key distribution simultaneously.It shows that the quantum key distribution protocol raised in this paper can resist a series of attacks like intercept retransmission attacks,middle attack and so on through the analysis of this paper.
