Cooperative spectrum sensing is recognized as an effective technology to improve the utilization of scarce radio spectrum resources. However, some Secondary Users (SUs) may be malicious, i.e. provide false sensing data, in an attempt to maximize their own utility gains. Such malicious behavior, if unchecked, the performance of cooperative spectrum sensing will be severely degraded. In this paper, the authors propose a novel trust scheme to support trustworthy cooperative spectrum sensing in cognitive radio networks.
