摘要
针对光网络攻击易被发现的问题,提出一种基于信号延迟插入的光网络攻击方式。该方法在不改变链路光学性能的基础上,利用信号延迟在系统中引起较高的串扰,极大的降低了系统的性能。仿真和实验结果表明攻击后目标光链路的误码性能大幅劣化而其光域内参数几乎没有变化,具有较好的隐蔽性和良好的攻击效果。
A novel optical network attack approach based on signal delay insertion was proposed to solve the problem of optical network attack being detected easily. Using signal delay insertion a higher crosstalk was introduced without changing the optical performance of links. Simulation and experiment results show that the bit error rate （BER） of the object optical link degrades abruptly, while its optical power and optical signal noise rate have no change, so this method has good invisibility and enormous damage effect.
