摘要/Abstract

摘要： 针对认知无线电网络中存在的仿冒主用户攻击问题,提出一种采用Hash链的防御方案。在主用户-主用户基站的通信阶段,通过自主更新Hash密钥对接收信号进行验证。而在主用户基站-认知用户的通信阶段,采用Hash链逆序发放的方法验证接收信号。利用Hash函数不可逆、防伪造的特点,提高方案的安全性,同时由于Hash链自主更新Hash值,无需在本地数据库预存大量数据,简化验证过程,减少系统开销,保证方案的高效性。分析结果表明,该方案能够有效防御认知用户网络中出现的仿冒主用户攻击。

Abstract: In order to avoid the adverse effects of the Primary User Emulation Attack(PUEA) in Cognitive Radio(CR) network,an authentication scheme based on Hash chain is proposed.Two occasions are considered in this scheme,one is PUEA between primary users and primary user base station,the other is between primary user base station and secondary users.In the view of the former,the paper adopts the self-updating Hash values to realize the signal verification,while dealing with the latter by issuing the Hash chain in a reversed way.This scheme makes the best of Hash characteristics of the irreversible and the forgery prevention to ensure the security,while the properties of self-updating reduce the storage content and simplify the validation process,so that the overhead of system can be reduced and the efficiency of the scheme can be guaranteed.Analysis shows that this scheme can solve the PUEA in CR network effectively.
