Security WSNs Routing Protocol Based on SEC-Tree

针对无线传感器网络(WSNs)的广泛应用及其对低能耗、高安全性迫切需求,提出SEC-Tree拓扑结构。以Sec-Tree为基础,设计了多层多路径路由协议,给出了一个自适应多路径路由算法。提出一种PSK生成算法,并将PSK应用于Sec-Tree初始化及路由维护中,实现了基于局部化的加密和鉴别技术,使该协议具有良好的安全特征、抗攻击能力和多跳、多路径路由的可靠特征。分析表明该路由协议具有高效安全的良好特性。

To cope with the emerging massive application of wireless sensor networks （WSNs） and its urgent attribute demands in low-energy consumption and high-security, a security and energy considering tree （SEC-Tree） topologized structure is proposed. Based on SEC-Tree, a multi-layer and multi-path routing protocol and a self-adaptation multi-path routing algorithm are presented. By applying pairwise shared key （PSK） in SEC-Tree initialization and route maintenance, a localized technology in encryptation and identification is brought forward to ensure the protocol high security, anti-attackability, and reliability in multi-hop and multi-path route. Theoretical analvsis indicates the high efficiency and security of the routing protocol.
