认知无线网络中收敛感知算法安全性检测
Security detection of the consensus-based spectrum sensing algorithm in cognitive networks
摘要
Abstract
Through altering local spectrum sensing data , attackers can launch spectrum sensing data falsification attack to affect the data updating process of other nodes , and lead to a wrong spectrum decision . For the consensus-based sensing algorithm , a security detection is implemented . Simulation shows that if there exists one attacker who can launch a spectrum sensing data falsification attack during the late stage of data convergence , others will be misled to converge sensing data to the value provided by the attacker . Therefore , all users in the local network will make a wrong decision . For the features of spectrum sensing in cognitive radio networks , considering the factors that can affect sensing data updating , some secure suggestions for spectrum sensing in distributed cognitive radio networks are introduced at the end of this paper .关键词
