传感器网络安全研究综述

新的无线传感器网络正在兴起。结点环境、无线通信方式、结点有限的资源使得其安全问题尤其突出。本文对无线传感器网络的安全问题及其解决方案作分类和综述。首先从多个维度对WSN安全攻击进行分类,并总结不同协议层次的攻击方法;然后讨论目前的解决方案并分类归纳密钥分配算法,重点分析随机密钥分配算法;提出一种新的研究思路。

Survey of Security in Wireless Sensor Networks(WSN)

A new kind of Wireless Sensor Networks(WSN) has sprung up.The environment of nodes,the way of wireless communication and the limited resources accentuate the problem of security in WSN.This paper presents a taxonomy and survey of both the security threats and related researches about WSN.Firstly,the paper classifies the security attacks in WSN.Then it discusses the current solutions.Key distribution schemes are classified and emphatically random key distribution algorithms are analyzed.Finally,a direction of future research in WSN is pointed out.
