Survey of Security in Wireless Sensor Networks(WSN)
A taxonomy and survey of both the security threats and related researches about WSN is presented and key distribution schemes are classified and emphatically random key distribution algorithms are analyzed.
Abstract
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.
