Aiming at the problems of the resource limitation of nodes and the error-prone communication chain in Wireless Sensor Networks(WSN), a secure and efficient remote authentication protocol based on WSN is presented. It adopts the centralized cluster-based hierarchical WSN to select the cluster head with the optimal percentage, and the cluster head is authorized to communicate with neighboring nodes; the network load balance is realized by minimizing the energy consumption of the nodes. Then each cluster head acts as a server, ensuring data authentication and exchange with each payload that delivers the message, and authenticating nearby nodes to form clusters. Simulation results indicate that the presented protocol is better than the existing protocols of improved Low Energy Adaptive Clustering Hierarchy(imp-LEACH) and secure LEACH(sec-LEACH) in the aspects of security, robustness, handshake duration, average energy consumption, and average network throughput.
