认知无线网络动态频谱感知决策安全协议框架研究

摘要

对认知网络频谱感知安全研究现状进行了分析,提出了一个频谱感知决策安全协议框架.对认知无线网络模型中相关组件、符号进行了定义,并对其结构和安全性进行了详细描述.通过与相关方案比较,结果表明该协议框架能够用来抵御频谱感知所面临的潜在威胁,使之进行正确的频谱决策.%This paper analyzed the state of the art in spectrum sensing security of cognitive radio networks,and presented a security protocol framework of spectrum sensing.It gave the related definitions for cognitive radio network model and analyzed its structure and security.This paper carried out comparisons with other solutions.The results show that the proposed framework can be used to ward off the potential threat on spectnun sensing in order to make correct decision.
