Anti-PUE Attack Based on Joint Position Verification in Cognitive Radio Networks

Cognitive Radio (CR) has been regarded as one of the options to solve the problem of low spectrum utilization. However, security problems of CR networks limit its applications. Most of the proposed security schemes are aiming at the location verification for incumbent transmitter, such as the verification technologies of Distance Ratio Test (DRT) and Distance Difference Test (DDT), but all of these methods have certain shortcomings. In this paper, a joint position verification method is proposed to enhance the positioning accuracy. Simulation results show that our method is simple and achieves high accuracy on transmitter location verification in CR network, which can improve the ability to resist PUE attack.
