Security Analysis Of Protocol Based On The Vulnerabilities In Wireless Sensor Network

With the wide application of wireless sensor network,its security issues attract more and more people's attention.Wireless sensor nodes own the characteristics of small memory,low communication bandwidth,being trapped easily,which makes the network vulnerable to attack.At the same time,a variety of wireless sensor network protocols and dynamic network topology have increased the risk of unpredictable.The existing attack detection framework and attack detection methods are proposed for a specific type of attack.These frameworks and methods have poor portability and scalability,and the complexity of the algorithm can reduce the communication efficiency in the network.In view of the limitations of the existing detection methods,this paper uses the research method of vulnerability attack to analyze the security of the protocol.Firstly,the security analysis of AODV and TreeCollection and Location Aided Routing(LAR)are carried out.Then,this paper proposes an extensible detection framework for LAR routing protocol.The framework consists of four parts: identifying the attack targets by matching key events and key variables;searching the reverse attack path and attack conditions based on the attack targets;generating the detection rules according to the guidance of attack targets and attack paths;using the extended Algebra The Wireless Mesh Networks(AWN)language formalizes the protocol.In the NS-2 platform,simulation scenarios verify the detection method.The experimental results show the feasibility and effectiveness of the framework.Based on vulnerability attacks to analyze the protocol,this method can give the entire attack process of attackers' view and dig out a comprehensive attack types.Therefore,this method is very important for studying the attack detection of wireless sensor network.In addition,in the course of analyzing the attack,we can search the attack path and the attack condition,which is of great guiding significance to prevent,detect and deal with the attackers and provides the ideas and direction for other researchers.
