针对WSN 中路由安全问题与传统安全路由算法之间的矛盾以及WSN 的特点,通过 采用WSNHC 加密和认证,解决路由信息泄露、路由信息篡改、DoS 攻击以及回放攻击问题。同时通过采取随机获取路由信息、中间节点应答以及优化路由等方法,解决WSN路由的效率问题。 关键字:WSN;WSNHC;路由机制 Abstract: The WSN routing in traditional security issues and security routing algorithm, as well as the contradiction between the characteristics of WSN, WSNHC through the use of encryption and authentication, routing solution leaked information, routing the letter distorted, DoS attacks and playback attack the problem. At the same time by taking random access routing information, intermediate nodes response and optimize routing methods to solve the efficiency of the WSN routing. Keyword: WSN;WSNHC; routing mechanism
