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。
This paper analyzes the attack source characteristics of in-band crosstalk attacks in optical networks and proposes a distributed multi-point intra-band crosstalk attack location algorithm based on two-parameter comparison. By comparing the parameters of optical signal-noise ratio Signal power parameters and the corresponding parameters detected directly upstream node to determine the location of the attack source. The simulation results show that the algorithm can locate the attack source quickly and accurately under multi-point attack.
