光纤通信网络窃听方法及防御措施

Optical Fiber Communication Tapping Methods and Precautions

近几年来,随着光纤通信网络窃听技术的发展,光纤通信安全性面临着新的挑战。一些光纤通信窃听技术以其隐蔽性特征而不能被检测到,因此研究光纤通信窃听技术及其防御措施是十分必要的。本文总结了近几年国际上光纤通信网络遭到窃听的案例,介绍了侵入式和非侵入式光纤窃听方法,分析了光纤通信网络安全的普遍误区,最后提出了防御光纤窃听的有效措施。

In recent years, with the rapid development of optical fiber communication network tapping technology, optical fiber communication security is facing new challenges. There are a number of known tapping methods of extracting or injecting information into a fiber link, while avoiding detection. Therefore, it is necessary to study optical fiber network tapping technology and its defensive measures. In this paper, the tapping cases in recent years were summarized. Optical fiber network tapping methods, both invasive and non-intrusive, were introduced. Optical fiber network security myths were analyzed. Finally, some measures to prevent fiber tapping or to nullify the significance of information tapped from fiber were also discussed.
