11.2. Crosstalk Attack Features and Monitoring Techniques

Among the attack methods listed previously, the crosstalk attack has the highest damage capabilities. In this case, an attacker injects a malicious signal with a very high power, far beyond the expected value. When this connection passes through a wavelength selective switch, the leakage energy (crosstalk) of this malicious connection significantly affects the normal connections passing through the same switch. Unlike other attacks, a crosstalk attack not only affects those connections that are sharing the same link or node with it, but also may induce attack capabilities to those connections that are attacked [3, 16–19] as explained below. We first describe the characteristics of crosstalk ...
