无线传感器网络的安全技术

The Security Technology of Wireless Sensor Network

无线传感器网络自身的特性决定了其易遭受攻击,其安全性也成为当前的研究热点。笔者对无线传感器网络的基础知识进行了介绍,总结了其三大特点、常见安全攻击及安全技术要求,分析了密钥管理、安全协议、鉴权认证及入侵检测技术,并对其发展方向进行了概述。

Wireless sensor network's own characteristics determine its vulnerability to be attacked,and its security also becomes the current research hotspot.The basic knowledge of wireless sensor network(WSN)was introduced,its main characteristics and common security attacks and safety technical requirements were summarized.And then,the key management,secure protocol,authentication certificate and intrusion detection technology,and its safety in the dir ection of development are reviewed.
