Cognitive Radio (CR) has been considered as a promising concept for improving the utilization of limited radio spectrum resources for future wireless communications and mobile computing. As the applications of Cognitive Radio Networks (CRNs) become more complex and widespread, the security mechanisms to protect CRNs become increasingly important. Specifically, Cognitive Radio Ad Hoc networks (CRAHNS) have the distributed multi-hop architecture and the dynamic network topology. These make spectrum availability and secure communication be the key distinguishing factors in CRAHNs. Protecting against attacks in CRAHNs cannot be done through cryptographic means due to the operation of wireless link itself. This leaves spectrum management as an open research area in the CRAHNs security field. This research mainly focuses on some specific aspects of spectrum management for CRAHNs. The objectives are defining security model, defining new types of attacks in spectrum sensing, integrating authentication and fault-tolerance in spectrum management scheme, and exploring the feasibility of secure communication using white spectrum in CRAHNS. The final goal is to provide a guideline for the definition of security models and to propose secure, fault-tolerant and hierarchical spectrum management schemes for different applications in CRAHNs.
