This paper presents a survey on Security Aware Channel Assignment for Cognitive Radio Networks (CRNs). Cognitive networks are networks are the sort of networks which show the attributes of leveraging the channel state information for the utilization of resources such as bandwidth and energy. The major challenge with cognitive systems comprising of cognitive networks is the fact that finding the channel state information with high accuracy is often extremely complex in nature. Moreover, securing such a network against attacks is even more challenging. This paper focuses on contemporary contributions in the field.
