A Framework for Implementing Security in Wireless Sensor Networks

(M.S. Thesis, Kamran Jamshaid)

Wireless sensor networks are edging closer to widespread feasibility with recent research showing promising results in developing and adapting new mechanisms to suit their environment. Secure communication between these distributed wireless devices is a desired characteristic, specially in scenarios where these sensors are being used for military and other mission-critical operations.

This work highlights some of the research challenges for extending secure communication over these resource-constrained wireless devices and points out why the current protocols do not scale well in this novel application realm.  A new key set-up protocol (SEKEN) is proposed which neatly fits  into most of the requirements for these device types. Our simulation results confirm the energy efficiency our protocol enjoys over some other current implementations. Our work also analyzes mechanisms to secure the underlying routing protocol in a typical hierarchical sensor network.
