Secure Cognitive Networks

Cognitive networks are intelligent networks that can automatically sense the environment and adapt the communication parameters accordingly. These types of networks have applications in dynamic spectrum access (DSA), co-existence of different wireless networks, interference management, etc. They are thought to drive the next generation of devices, protocols and applications. Clearly, the cognitive network paradigm poses many new technical challenges in protocol design, power efficiency, spectrum management, spectrum detection, environment awareness, new distributed algorithm design, distributed spectrum measurements, QoS guarantees, and security. Overcoming these issues becomes even more challenging due to non-uniform spectrum and other radio resource allocation policies, economic considerations, the inherent transmission impairments of wireless links, and user mobility. This paper will discuss the research challenges for security in cognitive networks (CNs) [1, 2]. It will present the security, and privacy requirements, threat analysis and finally proposes a framework for security using fast authentication and authorization architecture.
