Abstract: In transparent optical networks (TONs) traffic is carried over the optical fibers in the form of signals called lightpaths, creating a virtual topology over the physical interconnections of an optical fiber. This allows exchange of an enormous amount of data at a very high speed. A fault or an attack in the network can lead to data tampering and data loss. Unlike faults, malicious attacks may not be localized, and we cannot handle them with the standard fault-tolerance mechanisms in WDM networks. Security and attack management have become an important concern for the network operators due to high data transfer rates and vulnerabilities associated with transparency in WDM networks. In the recent years, there has been a significant increase in research interest to develop suitable mechanisms for mitigating the adverse effects of malicious attacks such as high-power jamming and tapping attacks in optical networks. In this thesis, we are addressing the security aware routing and wavelength assignment (RWA) problem for dynamic requests by using protection strategy known as dedicated path protection (DPP). We propose an Integer linear programming (ILP) formulation to maximize requests satisfaction and reducing the disruption in the network due to high power jamming attacks (In-band and out-band).
