分布式协作认知无线电SSDF攻击的防御策略综述

Survey on SSDF attack and defense for distributed cooperative cognitive radio

协作频谱感知可以提高频谱感知的可靠性,但其融合机制使得其易受频谱感知数据篡改(spectrum sensing data falsification,SSDF)攻击影响。为深入了解SSDF攻击防御算法的发展现状及趋势,总结了SSDF攻击典型的分布式防御策略,并对相应分布式防御算法进行了比较。最后依据目前相关研究中所发现的问题,对SSDF攻击分布式防御策略未来的研究方向进行了展望。

Cooperative spectrum sensing （CSS） improves the reliability of spectrum sensing, however, it is susceptible to spectrum sensing data falsification （SSDF） due to the fusion mechanism. To insight into the current research and development trend of defense strategy against the SSDF attack, several typical distributed strategies were concluded and the types of distributed algorithms were analyzed in several aspects. Finally, the future research of SSDF distributed defense strategy was prospected based on the problems found in the current research.
