摘　　要：认知无线电是一种智能频谱共享技术,可显著提高频谱的利用率。根据认知无线电在国内外的研究现状以及该技术的应用发展趋势,给出了认知无线电网络中安全路由的一个研究体系。该体系以一种混合式的网络结构为基础,将身份认证,密钥分配,组播树的创建,对当前空闲频谱信息进行合理定价,递减式组播模式以及跨层设计路由等问题结合在一起,形成了一个较为完备的认知无线电网络安全路由问题体系,为未来认知无线电安全路由的研究开拓了一条新路。Cognitive radio is a smart spectrum sharing technology which can effectively improve the utilization of radio resources.In this paper,proposes a research framework of security routing in cognitive radio networks according to the research status and the development trend of cognitive radio.Based on a composite network configuration,combine some interesting problems to form a relatively complete framework of security routing in cognitive radio networks,the problems includes identity authentication,key management, muhicast tree and reasonable pricing of idle spectrum information, decreasing multicast model and cross - layer routing design. The framework exploits a new way of study on security routing in cognitive radio networks in the future.
