摘要: 频谱感知是认知无线电通信的重要环节,SSDF(Spectrum Sensing Data Falsification)是协作频谱感知面临的严重安全威胁。SSDF攻击方式逐渐呈现动态化的趋势,传统防御算法因假定攻击强度保持不变而难以识别动态的篡改数据。针对动态化的SSDF攻击,提出一种基于能量分类器的抗SSDF攻击协作频谱感知算法。该算法首先通过分析动态SSDF攻击的特性,结合距离判别法将邻居节点能量分类,通过将分类结果与本地结果进行对比来识别恶意邻居节点;然后本地节点在滑动时间窗内根据历史频谱判决信息和当前频谱判决信息建立信誉模型,并由此更新各邻居节点的信誉值;最后,本地节点实施加权协作频谱感知。仿真结果表明:相比LDCSS(Largest Deviation-based distributed Cooperative Spectrum Sensing)算法和RBCSS(Reputation-based Cooperative Spectrum Sensing)算法,所提算法在动态SSDF攻击的攻击强度接近阈值时频谱检测概率分别提高了15%和16%,显著增加了认知网络的协作频谱感知性能,提升了频谱共享的效率。
