This chapter provides an overview of security issues in Wireless Sensor Networks (WSN). If first describes the security requirements followed by common attacks and threats in such networks. Then, some of the important security mechanisms such as encryption/decryption, key management and distribution are presented. This is followed by description of implementations of security mechanisms available in current generation WSN operating systems such as TinyOS. © 2010 by World Scientific Publishing Co. Pte. Ltd.

Security Trends and Challenges in Wireless Sensor Networks

Handbook on Sensor Networks

Landmines are one of the most environmentally destructive aftermaths of war that the world faces today. Integrating sensor networks with landmines can enable the landmines to be dynamically and securely controlled by troops on the ground. This paper describes the design and implementation of a sensor node based "smart mine" that helps achieve these objectives, while supporting secure wireless communication. The landmines are controlled by integrating them with sound sensors and actuator circuits, using Crossbow wireless sensor devices. For reliable communication, hybrid cryptography is implemented using TinyECC based Public Key Cryptography (PKC) and Trivium based symmetric cipher which was ported to TinyOS 2.0. © 2012 IEEE.
