摘要

针对认知用户的协作感知行为不确定性，提出一种基于D-S证据理论的信任评估机制——HardGuard，为硬判决融合算法提供保护，使其成为具有抑制频谱感知数据伪造（SSDF）攻击能力的可信协作频谱感知算法。HardGuard采取感知数据预处理措施，在融合之前有效过滤虚假感知数据，规避了恶意用户的影响。仿真结果表明，HardGuard能使硬判决融合算法面对SSDF攻击时保持较好的感知性能。

Abstract

Aiming at the uncertainty behaviors of cognitive users

an evaluation mechanism based on D-S theory

called HardGuard

was proposed to guard the hard-decision fusion schemes. Before fusing data

HardGuard will filter out false sensing data to avoid the impact of malicious users. The simulation results show that HardGuard is effective in suppressing spectrum sensing data falsification attack

and it can ensure the better sensing performance for the hard-decision schemes.
