Cluster-Based Security for Wireless Sensor Networks

This paper examine the problem of adding security to cluster based communication protocols for homogeneous wireless sensor networks consisting of sensor nodes with severely limited resources, and propose a security solution where clusters are formed dynamically and periodically. Our solution describes re-keying function protocol for wireless sensor networks security. We proposed the local administrative functions (LAFs) as master function, re-keying function, and derivation function is imprinted with sensor node. A security and performance analysis show that is very efficient in computation, communication, storage and that our method is very effective in defending against many sophisticated attacks.
