【摘要】：量子密钥分发系统由于能够提供一种物理上安全的密钥分发方式,因此成为量子信息领域的研究热点,其中如何在现实条件下保证量子密钥分发的无条件安全性是该领域的一个重要研究课题。从经典保密通信系统中具有完善保密性的一次一密体制出发,介绍了量子密钥分发系统的应用模型和整体保密通信系统的安全性基础,以及自第一个协议被提出以来量子密钥分发现实无条件安全性的研究进展,重点介绍了针对现实条件安全漏洞的各种类型的量子黑客攻击方案、防御方式,以及最近两年被广泛重视的与测量设备无关的量子密钥分发系统的理论和实验进展。
[Abstract]:Quantum key distribution system (QKD) has become a hotspot in the field of quantum information due to its ability to provide a physically secure key distribution method. How to guarantee the unconditional security of quantum key distribution is an important research topic in this field. This paper introduces the application model of quantum key distribution system and the security foundation of the whole secure communication system. As well as the research progress of quantum key distribution reality unconditional security since the first protocol was proposed, this paper focuses on introducing various kinds of quantum hacker attack schemes and defense methods aiming at the security vulnerabilities of realistic conditions. And the theoretical and experimental progress of the quantum key distribution system which is independent of the measurement device has been paid much attention to in the last two years.
