摘要/Abstract

摘要： 量子密钥分发是一种重要的量子通信方式。为了提高量子密钥分发的可行性、安全性和效率，提出了一种基于单粒子态的具有双向认证功能的多方量子密钥分发协议。在协议中, 量子网络中的任意两个用户均可在一个半可信第三方的帮助下，进行双向认证并共享一个安全的会话密钥；协议中作为量子信息载体的粒子不需要存储，这在当前技术下更容易实现。安全性分析表明所提出协议在理论上是安全的。

关键词: 单粒子；多用户量子密钥分发；身份认证；半可信第三方

Abstract: Quantum key distribution is an important way of quantum communication. In order to improve the feasibility, security and efficiency of quantum key distribution, a mutual authenticated multiparty quantum key distribution protocol based on single particle state is proposed. In this protocol, any two users in a quantum network can perform mutual authentication and share a secure session key with the assistance of a semi-trusted third party. The particles used as quantum information carriers are not required to be stored, which is easier to implement under current technology. The security analysis shows that the proposed protocol is secure in theory.

Key words: single particle; multiparty quantum key distribution; identity authentication; semi-trusted third party
