摘要
量子通信技术在军事、国防、金融等信息安全领域有着重大的应用价值和前景,因此很多国家都对量子通信技术的研究加大了投入力度,并取得了很大的进展。量子密钥分发(QKD)是量子通信技术里发展最为成熟的技术,目前已经进行到实用化阶段。我们总结了QRNG和QKD技术的发展现状,提出了基于现有光网络架构进行改造的QKD融合组网方案和一种将QKD技术与经典密码学结合的QKD密钥分发应用协议,并对今后应用的研究方向进行了简单分析。
Quantum communication technology has great application value and prospects in the fields of military, defense, finance and other information security. Therefore, many countries have increased their investment in quantum communication technology research and made great progress. QKD(Quantum Key Distribution) is the most mature technology in quantum communication technology and has been put into practical use. The development status of QRNG and QKD technologies is summarized. A scheme of QKD fusion networking based on existing optical network architecture and an application protocol of QKD key distribution which combines QKD technology with classical cryptography are proposed. The research direction of future applications is briefly analyzed.
