无线传感器网络安全路由协议的设计与分析

路由安全是无线传感器网络安全的关键因素,而现有的无线传感器网络路由协议在设计时都没有充分考虑安全问题。在充分考虑网络路由协议攻击方法和无线传感器网络自身特点的基础上,结合基于ID的认证密钥协商技术以及秘密共享技术,提出了无线传感器网络路由的安全策略及其设计思想。同时,在路由建立阶段增加安全机制,提出了一种较优的安全路由协议。经过安全性分析,该路由协议可防御虚假路由信息、Sybile、确认欺骗等常见攻击。

Design and Analysis of Secure Routing Protocol for Wireless Sensor Networks

The route security is the key factor of the security of wireless sensor networks. However, when designed, none of the existing routing protocols has made sufficient consideration on security issues. Based on the enough consideration on the attack methods for network routing protocols and the characteristics of wireless sensor networks, the security strategy and the design method of the network routing protocol are elaborated, in which the ID-based authentication and key negotiation technology and the secret sharing technology are adopted. At the same time, the security mechanism is added to the routing establishment process and then an optimal security routing protocol is proposed. Analyses show that this protocol can be used to defend familiar attacks such as spoofed routing information, the Sybile attack, and acknowledgement spoofing.
