Abstract
For secure sensor communication, pairwise key establishment between sensor nodes is essential. In this paper, we propose cluster based key establishment mechanism, in which clusterheads distribute key materials at the requests of its own members. In our mechanism, only nodes located close to or in the neighbor clusters get the key information. Our proposal decreases the computation and memory requirement, and increases the degree of connectivity and resilience against node capture.
