Abstract


Wireless sensor networks as computing, communication and sensor technology combined with the three product is a new information acquisition and processing technology , has become an active branch of research in the field of computer science . As wireless sensor networks are generally configured in a harsh environment , no one region or enemy positions , combined with the inherent vulnerability of wireless sensor networks , thus the network security caused great concern , it also gives the theory researchers and engineers and technicians a large number of challenging research topic . Calculate the speed of the sensor nodes , power energy , communication capabilities and storage space is very limited circumstances , the security system is not suitable for used in wireless sensor networks . Research of secure communication protocol for wireless sensor networks in recent years , emerging safety program is still in the phase of theoretical research , still far away from the actual application and the formation of a universally accepted standard . In this paper, the wireless sensor networks and their security depth and meticulous research , a more comprehensive knowledge and understanding of the characteristics of wireless sensor networks , the research progress of the weaknesses , security requirements, and security issues . On this basis , the article refers to the currently recognized as the authoritative network security framework agreement - SPINS (Security Protocols for Sensor Network), a wireless sensor networks based on hierarchical topology design of secure communication protocols . The protocol scheme using LEACH algorithm and to make up for its lack of security . Topology establishment phase increases the authentication of the base station the identity of the cluster head , so as to ensure the legitimacy of the head of the cluster ; added a one - way hash function and a shared key in key management , so that the encryption key and authentication key cycle dynamic changes , thereby enhancing the security of network communication . Agreement to consider the characteristics and limitations of the wireless sensor networks , also sought to try to meet the security needs of the network communication , confidentiality, integrity , freshness and certification . Finally, the concrete implementation of the agreement on a new type of wireless sensor network operating system TinyOS nesC language and its performance analysis , the analysis results show that the agreement is feasible .
