A Key Management Scheme Using ECC with Grouping Cluster
Lijuan Sun · Computer Technology and Development · 2012
Based on Elliptic Curve Cryptography(which is short for ECC) mechanism,propose an ECC key management scheme for a wireless sensor network which has a logical grouping structure within the cluster.This scheme divides the cluster into multiple logical groups,and each group shares different communication key.The cluster header controls every group's communication key in real time and the cluster members communicate with the cluster header through the group's sharing secret key they belonged to which can ensure the safety of communication.The theory analysis and simulation results show that this scheme effectively reduces communication power consumption during the process of negotiating secret key under the premise of ensuring key security,is very suitable for a large-scale wireless sensor network of limited resources.
