Security analysis in cognitive radio network

Abstract

In wireless communication system Cognitive Radio(CR) is a structure that can gives an intelligent privileges to communicate over internet. Cognitive Radio(CR) intel- ligently allows user to use free spectrum. It is dynamically configured and it allows more user in wireless network. IEEE 802.22 standard cognitive radio (CR) was de- veloped first. Due to spectrum sensing, sharing, mobility there is a issue in security. Ensuring security and using spectrum efficiently is challenging. In this paper, the se- curity threats of cognitive radio network are briefly discussed. After explaining some of possible attack, we have emphasized on Primary user emulation attack(PUEA). With the existing system model the probability of false alarm and miss detection has been studied. MATLAB R2010a tool has been used to analyze the model. This pa- per we have shown Neyman-Pearson Criterion to detect PUEA and a for different malicious users status to create false alarm and miss detection
