Abstract

Cognitive Radio (CR) is regarded as one of the best options to solve the problem of low spectrum utilization. However, information security of CR limits its wide application. Most of the known security schemes are aiming at the location verification for incumbent transmitter, but it is not available for Ad hoc. In this paper, a new security scenario in physical layer is proposed. It takes advantage of the "fingerprint" verification of the transmitter against primary user emulation (PUE) attacks. The phase noise of the noisy carrier is extracted from the received modulated signal and directly applied to identify the transmitter.
