摘要:

协作频谱感知是认知无线电中实现频谱有效利用的关键环节,但协作频谱感知由于其聚集感知数据的特点,为恶意用户提供了可乘之机。恶意用户可以通过实施频谱感知数据伪造(spectrum sensing data falsification,SSDF)攻击的方式,使认知无线电系统不能如实地根据外界环境进行动态的频谱切换。为深入理解SSDF攻击,掌握其防御对策的研究现状及发展趋势,从攻击手段、攻击形式和攻击策略3个角度细化出具体的SSDF攻击类型,总结了目前SSDF攻击的典型防御对策。同时,针对目前相关研究中所存在的问题,明确了一些有待继续研究的方向。

Abstract:

Cooperative spectrum sensing is the core of cognitive radio technologies to utilize spectrum resources effectively. However, cooperative spectrum sensing schemes are vulnerable to abuses by false sensing data, and thus offering opportunities for malicious users. By launching the spectrum sensing data falsification attack, some of them can make a well cognitive radio system useless. To further understand the SSDF attack and its current research situation and development trend, the types of SSDF attack were analyzed in the form of three aspects, and several typical security methods were concluded. Meanwhile, the current problems of SSDF attack and research trends in this area were discussed.

Key words: cognitive radio, cooperative spectrum sensing, wireless communication, spectrum sensing data falsification attack
