A Novel Authentication Mechanism for Cognitive Radio Network

Abstract

By employing an efficient authentication protocol the security of the Cognitive radio Network can be upgraded. This paper portrays a strategy for recognizing the Primary client Emulation Attacks in a CRN using cross layer approach. A few kinds of attacks have been discussed in this paper and an authentication scheme to detect PUEA has been presented. It is identified that the physical layer authentication method can serve as a faster authentication method but with low accuracy in detection.And a cryptography based authentication protocol can serve as a slower authentication method but with high accuracy in detection. In this paper a cross layer confirmation plot that joins both the physical and higher layer authentication is defined. The proposed method can provide good accuracy in detection without sacrificing the speed of the detection.A detecting procedure to detect PUEA in a CRN for a single user has been defined in this paper.
