基于分簇的无线传感器网络安全组播路由协议

针对无线传感器网络节点能量、计算和带宽有限的特点，提出一种适用于无线传感器
网络的基于分簇的安全组播路由协议（CSMR）。该协议采用了HiM-TORA 的树形组播寻路机制，并引入了TESLA 密钥链与时间同步等安全机制，能够自动且安全地构建覆盖所有组播组成员的组播树，且在路由建立的阶段就能对成员的身份和相关的信息进行认证，有效的防止了对组播路由的各种攻击。同时分析了该协议的安全性与有效性。

Clusering-Based Security Multicast routing Protocol for wireless sensor network Cheng Yali, He Bo (Ocean University of China, Qingdao, China 266071) Abstract: The wireless sensor network is characteristic of limited node energy, computation and memory, so many traditional security methods, such as the public key algorithm and the digital signatures, are hardly used on it. To solve such problems, we proposed a novel secureity multicast routing protocol for clustering-based wireless sensor network(CSMR). In CSMR, we use HiM-TORA to construct multicast routing tree, and include TESLA key chain technology to make it secure. In the process of constructing the routing, it can authenticate the group member’s identifier and correlation information.The scheme is proved valid through the theoretic analysis.
