Research And Implementation On Vulnerability Scanning System Of Wireless Sensor Network

Wireless Sensor Network(WSN)is a new discipline belonging to the field of information technology in the current international subordinate,which combines wireless communication technology,microelectronics,sensor technology,embedded computing technology,information security technology and data integration and management technology and many other frontier,the WSN had been in a number of areas,military,monitoring,environment,consumer,health care,transportation and other widely used.The radio channel,limited energy,distributed control and other characteristics that have made wireless sensor networks easily to be attack,there are a lot of security vulnerabilities in the Wireless Sensor Network,but the current lack of effective vulnerability scanning technology.Structural composition and application scenarios for wireless sensor networks are very different from traditional wireless networks.Energy,processing capacity,storage capacity and communication capabilities of sensor nodes are very limited,so efficient use of energy is an important design goal.Wireless sensor network and traditional networks,whether technical,management and services,or security mechanisms have a great difference.So the traditional network vulnerability scanning methods can't effectively detect the wireless sensor network security vulnerabilities.Through in-depth research on wireless sensor network,a based perception-collaboration vulnerability scanning method in wireless sensor networks has been proposed.The main work is as follows:First of all,on the base of analysis the wireless sensor network characteristics and security threats,the wireless sensor network vulnerabilities can be summarized of the basic vulnerabilities,the task vulnerabilities and system vulnerabilities in accordance with the different threaten objects.By reading the relevant literature and information,the author summarizes the classification of traditional vulnerability scanning technology and the main method,and its advantages are analyzed.Secondly,we propose a perception-collaboration vulnerability scanning program of wireless sensor network,which consider the characteristics of wireless sensor networks,and the different needs with the traditional network vulnerability scanning.It is possible to ensure a lesser quantity of wireless sensor network security,and elaborate methods for this critical part of the technology.Finally,the wireless sensor network vulnerability scanning system was designed,implemented and tested.Based on the perception-collaboration vulnerability scanning program,the design of the WSN vulnerability scanning system architecture,and the implementation of key modules are completed.Build a test environment using the sensor nodes,the test results show that the perception-collaboration vulnerability scanning method can scan the security vulnerabilities of wireless sensor network effectively.
