光网络安全现状与量子加密应用前景分析

Analysis on Optical Network Security Status and Quantum Cryptography Prospects

光网络作为信息社会的骨干基础设施,面临着日益复杂化的安全形势,针对光网络物理层的破坏和窃听将对网络信息安全构成严重威胁。本文首先对光网络安全隐患进行梳理,其次对目前光网络物理层安全防护技术进行综述,最后对基于量子密钥分发的光层加密技术的试点应用、产业化现状与存在问题进行分析,并给出发展前景展望。

Optical fiber communication network is the backbone of information society. Optical network suffer from compli- cated security situation, both service disruption and eavesdropping will lead serious information security threat.In this paper, optical network security risks are presented firstiy, security protection technology in optical network, such as reinforcement, encryption and stealth is analyzed secondly, finally the status, problems and prospects of quantum key distribution based optical layer encryption is discussed.
