量子密钥分发网络国际标准研究进展
Research progress on international standards for quantum key distribution networks
摘要
Abstract
To address the threat posed by quantum computing to traditional cryptographic systems and to promote the transition of quantum key distribution(QKD)networks from experimental stages to large-scale applications,this paper systematically re-views the latest advancements in protocol architecture,security evaluation,and network interoperability by international QKD standardization bodies.It analyzes the shortcomings of existing standards in areas such as device-independent security and cross-domain interoperability.This paper summarizes breakthroughs in QKD technology regarding transmission distance,key generation rate,and integration,and proposes key standardization pathways for large-scale networking.These include develop-ing unified interface protocols,enhancing cross-organizational collaboration,and advancing integrated space-ground standards development.Finally,the future landscape of QKD networking is outlined.关键词
