基于辅助节点的安全协作频谱感知
Secure Cooperative Spectrum Sensing Based on Helper Nodes
摘要
Abstract
In Cognitive Radio Network(CRN), it exists the secure problem that adversaries emulate the characteristics of Primary User(PU) transmissions in order to occupy the authentic spectrum, and other Cognitive User(CU) mislead the existence of PU. Aiming at this problem, a secure sensing mechanism based on helper nodes is proposed. This mechanism relies on link signatures and cryptographic mechanisms to identify the PU activity. The corresponding fusion algorithm for this scheme is also proposed. The proposed algorithm can identify such adversaries efficiently without any modification to Primary Network(PN), and acquire robust results by utilizing sensing data of trust nodes. The simulation results show that this algorithm can achieve better detection performance in hostile environment than K rank, And and Or algorithm.关键词
