量子保密通信网络架构及移动化应用方案

作为新一次量子革命中率先实用化的代表性技术，量子密钥分发（quantum key distribution，QKD）为信息安全领域带来了有望实现长期安全性保障的可行方案，近年来从协议设计、技术研发、网络部署到实际应用都取得了长足的进步。首先探讨了将点对点QKD技术扩展到多用户量子保密通信网络的架构设计；进一步，结合经典密码学方案，提出将QKD生成的量子密钥在移动终端侧应用的增强解决方案，使得QKD技术可应用于更广泛的移动化场景。

Quantum secure communication network architecture and mobile application solution

As the first practical representative technology in the new quantum revolution,quantum key distribution (QKD) brings a promising solution to achieve long-term security guarantee,which has made series of progress from research to practical deployment and applications in recent years.The architecture design of quantum secure communication network was firstly discussed,which extended point-to-point QKD link to multi-user QKD network.Furthermore,combining with the classical cryptography,an enhanced solution was proposed to apply the quantum key generated by QKD to the mobile terminals,which offered the possibility to apply QKD in general mobile applications.
