Security routing protocol SNEP analysis and simulation for wireless sensor networks

以提供可靠保密通信为目标的安全路由协议的分析是无线传感器网络安全基本研究领域之一.阐述了针对无线传感器网络的攻击手段所采取的措施,研究了安全路由协议,重点研究了其中的传感网络加密协议(Sensor Network Encryp-tion Protocol,SNEP),并进行了仿真实现,最后针对无线传感网络的攻击方式对SNEP的安全性进行了分析.结果证明SNEP协议具有数据机密性、数据认证、防御重放攻击等安全服务.

The analysis of security routing protocol whose main objective is to provide reliable communication is one of the basic research field of secure wireless sensor networks. This paper described the solutions of various attacks for wireless sensor networks, and investigated security routing protocol. It especially focused on sensor network encryption protocol SNEP, and simulated the protocol. Furthermore, the authors analyzed the security for SNEP. The results show that SNEP has security services including data confidentiality, data authentication, and replay attacks.
