量子保密通信研究进展与安全性分析

Progress and Security Analysis of Quantum Cryptography Communication

量子保密通信基于量子密钥分配和"一次一密"加密体制,能够提供无条件安全性保证,成为学术界和产业界研究关注的焦点。在介绍量子保密通信协议原理、关键器件和网络架构的基础上,重点分析了实际量子密钥分配系统的安全漏洞、攻击手段和安全性对策以及测量设备无关量子密钥分配技术研究进展,并对量子保密通信技术的安全性挑战、发展方向和应用前景进行了展望。

Quantum cryptography communication, which provided unconditional security by means of quantum key distribution and one-time pad encryption, has become one focus of communication academia and industry. The quantum key distribution protocol, devices, and network architecture were reviewed. The security loopholes and quantum hacking schemes of practical system were analyzed. Corresponding security countermeasures were summarized. Recent progress of measurement-device-independent quantum key distribution was also introduced. In the end, the security challenge, development direction and prospects of quantum cryptography communication were also discussed.
