Outline of Final Research Achievements

Wireless Sensor Networks (WSNs) consist of battery-operated, limited memory and computational power sensor nodes. It is important to achieve secure communication among WSN. In this research, we have studied a group key exchange (GKE), application of hash functions to GKE, formal security proof, and simulation of GKE. The following are our results. 1.We have proposed T-robust scalable GKE with communicational and computational complexity O(log n) for n parties. Our GKE not only has a resistance to party failures resulting from party crashes, run-down batteries, and network failures, but also satisfies scalability to parties’ environment such as computational resources, batteries, etc. 2.We have redesigned GKE using bilinear pairings to reduce the computational and communicational complexity among a small group of parties. We have also redesigned GKE among a large number of parties, where each party is in a different environment.
