A Dynamic Cluster-Based Key Management Protocol in Wireless Sensor Networks

Recent advancement in wireless communication and microelectronics has enabled the design and development of wireless sensor networks with low cost, low energy consumption and high utilization. Many cluster-based wireless sensor network routing protocols have been proposed. However, most of them take little consideration on communication protection, which is important to ensure the network security. In this paper, a lightweight key management approach is presented. Its analysis shows that this approach is an effective solution to the key management of hierarchical clustered wireless sensor networks.
