Abstract
Dynamic Spectrum Access (DSA) systems are being developed to improve spectrum utilization. Most of the research on DSA systems assumes that the participants involved are honest, cooperative, and that no malicious adversaries will attack or exploit the network. Some recent research efforts have focused on studying security issues in cognitive radios but there are still significant security challenges in the implementation of DSA systems that have not been addressed.

In this talk, I will survey the security issues in DSA. I identify various attacks (e.g., DoS attacks, system penetration, repudiation, spoofing, authorization violation, malware infection, data modification, etc.). While existing approaches to securing IT systems can be applied to DSA so address some of the problems, others require new approaches. I discuss one new approach in which spectrum sensing becomes a service and consider its implications for security and beyond.
