认知无线电是一种革命性的技术，有望缓解频谱短缺问题，并带来显着的提高频谱利用率。频谱感知是认知无线电的基本机制之一，是一个活跃的研究领域。虽然频谱感知的操作方面正在积极研究，但其安全方面却很少受到关注。在本文中，我们讨论的安全问题，可能构成严重威胁的频谱感知。具体来说，我们专注于两个安全威胁-现任仿真和频谱感知数据伪造-这可能会造成严重破坏分布式频谱感知。我们还讨论了应对这些威胁的方法以及实施此类对策必须克服的技术障碍。
Cognitive radio is a revolutionary technology that promises to alleviate the spectrum shortage problem and to bring about remarkable improvement in spectrum utilization. Spectrum sensing is one of the essential mechanisms of CR and is an active area of research. Although the operational aspects of spectrum sensing are being studied actively, its security aspects have attracted very little attention. In this paper, we discuss security issues that may pose a serious threat to spectrum sensing. Specifically, we focus on two security threats - incumbent emulation and spectrum sensing data falsification - that may wreak havoc in distributed spectrum sensing. We also discuss methods for countering these threats and the technical hurdles that must be overcome to implement such countermeasures.
