基于节点位置信息的无线传感器网络安全组播路由协议

A Geographic-location-information-based Secure Multicast Routing Protocol in Wireless Sensor Networks

针对如传统的安全路由协议不适用于组播通信的问题,提出一种基于节点位置信息的安全组播路由协议。采用随机密钥预分布模型对无线传感器网络中的节点进行密钥预置,并利用节点位置信息建立虚拟Steiner树,根据虚拟Stei-ner树建立安全组播路由协议,再对此协议进行安全性分析。结果表明：该协议能使每一个节点与其邻居节点间共享一个对称密钥,阻止非法节点参与路由过程,达到建立安全组播树的目的。

The paper proposes a geographic-location-information-based secure multicast routing protocol in wireless sensor networks for the traditional secure multicast routing protocol not applying to multicast communications.Basic random key scheme model has been proposed to distribute key among nodes of wireless sensor networks,and the geographic location information is used to build the virtual Steiner tree by which the secure multicast routing protocol is built.The security of this protocol has been analyzed by the multicast tree generation algorithm.The results show that the protocol enables each node share a symmetric key with its neighbor nodes,to stop the false nodes involved in the routing process for the purpose of establishing a secure multicast tree.
