摘　　要：针对认知无线电网络中出现的模仿主用户攻击和自私行为攻击问题,提出一种基于簇的分布式认知无线电网络安全体系结构。这种安全体系结构通过采用数据加密和认证等安全技术解决无线网络中原有的安全问题,通过在主用户基站与认知用户间使用Hash匹配技术可解决模仿主用户攻击问题,通过簇头向目的节点发送转发节点的可用频谱信息可解决自私行为攻击问题。由分析可知该安全体系结构是安全、高效和可行的。To solve the primary user emulation attack and selfish misbehaviors in cognitive radio networks, this paper presents cluster-based security architecture for distributed cognitive radio networks. This security architecture solves the traditional wireless network security threats by using the data eneryption, authentication and other security technology. The Hash matching technique between primary user base station and secondary users to prevent from the primary user emulation attack, the cluster heads send available frequency information of forwarding nodes to objective nodes to solve selfish misbehaviors. By analyzing, we know this security architecture is safety, efficiency and feasibility.
