协作频谱感知中抗SSDF攻击的认知用户不确定性行为评估

doi:10.11959/j.issn.1000-0801.2015025

Abstract

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.

Key words: cooperative spectrum sensing, hard decision fusion, SSDF attack, trust
