Application Driven Cluster Based Group Key Management with Identifier in Mobile Wireless Sensor Network

This paper proposes and analyzes a scalable and efficient cluster based group key management protocol by introducing identity based infrastructure for secure communication in mobile wireless sensor networks. To ensure scalability and dynamic reconfigurability, the system takes a cluster based approach by which group members are broken into clusters and leaders of clusters securely communicate with each other to agree on a group key in response to membership change and member mobility events. Through analysis we have shown that our protocol has high probability to be resilient for secure communication among mobile nodes. Finally, it is clarified that the proposed scheme is efficient for secure positioning in wireless sensor network.
