Abstract	Wireless spectrum is precious, so there are always requirements of dynamic shared spectrum techniques and an intelligent wireless communication system, such as Cognitive Radio Network (CRN). Although, CRN provides awareness, reliability, adaptability, high quality services and flexibility to its users but it has also opens the door for lots of threats and attacks. In this paper, various possible attacks and threats along with the possible solutions are discussed. This article has also proposed a trust based security algorithm enabling cognitive radio to access the distributed computation, storage, and resources available in cognitive radio environment. Proposed trust based algorithm is based on the location awareness and distance between the mobile user. Trust is calculated from the actual received power and trust metrics are determined by combining the requirements of the trustworthiness and the QoS of the links with the route. In this algorithm, three dimensional (3D) coordinates system is used to verify the location of the primary user and malicious user. Proposed algorithm has defined the trust factor of various users on the basis of trustworthiness. The simulation results have demonstrated the effectiveness of the proposed trust algorithm for all three types of user i.e. primary, secondary and malicious user, in the terms of both security and performance.
