A Clustering-Based Scalable Key Management Protocol for Ad Hoc Networks

In this paper, we address a scalable key management protocol for ad hoc networks, this protocol is based on new clustering technique. The network is partitioned into communities or clusters based on affinity relationships between nodes. To ensure trusted communications between nodes we proposed two types of keys generated by each clusterhead. The protocol is adaptive according to the limitation of the mobile nodespsila battery power and to the dynamic network topology changes.
