10.1 Abstract Wireless sensor networks have been rapidly emerging recently and the applications range widely. To protect the networks from different kinds of attacks, security in wireless sensor networks plays a crucial role and has received increased attention in the applications, especially those deployed in hostile environment such as battlefield monitoring and home security. However, the stringent resource constraints, such as energy, communication and computation capability, and memory, etc., pose many new challenges in security design. In this chapter we discuss the security issues in wireless sensor networks and present a comprehensive survey of the approaches published in recent literature. Some ongoing research work as well as open problems are also discussed.
