Abstract

With the expansion of wireless sensor networks, the need for securing the data flow through these networks is increasing. These sensor networks allow for easy-to-apply and flexible installations, which have enabled them to be used for numerous applications. Due to these properties, they face distinct information security threats. Security of the data flowing through across networks provides the researchers with an interesting and intriguing potential for research. Design of these networks to ensure the protection of data faces the constraints of limited power and processing resources. The author provides the basics of wireless sensor network security in this chapter to help researchers and engineers in better understanding of this applications field. In this chapter, the author provides the basics of information security, with special emphasis on WSNs. The chapter also gives an overview of the information security requirements in these networks. Threats to the security of data in WSNs and some of their counter measures are also presented.
