Analysis And Application Of Security About Wireless Sensor Network

Known as one of the three global high-tech industries of the future, Wireless Sensor Networks (WSN) has a wide applying prospect, by integrating sensors, embedded computing, networking, wireless communications and distributed information processing technology. With the advantages of self-organizing, multi-hop routing, high fault tolerance, WSN can not be replaced to meet the demands of the battlefield information system, which have many specical properties such as high flexibility, high survivability, high reliability, large-scale network and so on.Since it is difficult to guarantee the security for its own features, WSN has been seriously restricted for application. Nowadays, promoting the characteristics of security and building a safe network mechanism is becoming an important research field. At present, the research of network security is focused on three major aspects:aggressive behavior, defense against attacks and system vulnerability. Therefore, the research on security issues of WSN is of great significance and urgency.The main task of the thesis is to study the security threats facing by WSN. With the security analysis of military application based on WSN, we try to find the hidden safety problems and propose the corresponding dealing strategies and improved schemes.
