Localization Algorithm of Multiple Intra-channel Crosstalk Attack Based on Comparison of Double Parameters in Optical Network

分析了光网络中带内串扰攻击的攻击源特点,提出了一种基于双参数比较的分布式多点带内串扰攻击定位算法,该算法通过同时比较节点本身检测到的光信噪比参数和信号功率参数以及直接上游节点检测到的对应参数来判断攻击源的位置。仿真结果表明,该算法能够实现对多点攻击情况下攻击源的快速准确定位。

The characteristics of the intra-channel crosstalk attack source were analyzed.A distributed multiple intra-channel crosstalk attack localization algorithm was proposed based on comparison of double parameters.The algorithm can acquire the position of attack resource by comparing both the optical signal noise ratio parameter and the signal power parameter and its direct upstream neighbor one detected.Simulation results show that accurate localization of attack source can be achieved in the case of multiple attacks.
