Avoiding monopolization: mutual-aid collusive attack detection in cooperative spectrum sensing

协作频谱感知中的 MAC 攻击及其检测机制研究

  • 77 Accesses

摘要

创新点

  1. 1.

    发现了一种新的频谱感知数据伪造攻击模式-互助式合谋攻击 (简称 MAC 攻击)。 多个恶意用户形成互助式合谋攻击组, 相互抬高信任值, 用于躲避信任机制检测, 达到垄断空闲频谱资源的攻击目的。

  2. 2.

    针对感知数据的二元特性, 引入 “0–1” 相似度方法设计MAC攻击的检测机制-DMAC, 可在避免复杂数学运算的前提下, 检测出 MAC 攻击者。

  3. 3.

    通过 DMAC 对信任机制的优化, 在信任评估中阻止 MAC 攻击者虚构的“诚实感知总次数”增长, 使得 MAC 攻击者难以抬高信任值。
