Protection of Optical Networks against Interchannel Eavesdropping and Jamming Attacks

Wavelength-division-multiplexing (WDM) optical networks provide higher data rate and stronger security than many other transport technologies. Yet optical networks are not completely immune to security treats, among which are interchange attacks by exploiting the crosstalk effects, including eavesdropping and jamming. In this paper, we develop novel routing algorithms to minimize light path overlapping thus minimize the damages caused by interchange attacks. The algorithms are evaluated by complexity analysis and computer simulations.
