METHOD FOR ESTABLISHING PAIRWISE KEY BASED ON HEXAGONAL CLUSTERING SENSOR NETWORK ARCHITECTURE

摘要

A method for setting a key on a sensor network based on a hexagonal clustering structure is provided to improve the probability of setting the key directly by increasing resistance against capturing a node. A method for setting a key on a sensor network based on a hexagonal clustering structure includes the steps of: distributing data related to the key to a cluster head arranged in a center of each cluster and a node to be arranged by a hexagonal cluster of the sensor network(S100); grasping a neighboring node among nodes closely arranged in a center of a cluster head(S200); setting a pairwise key between the nodes and between the cluster heads grasped in the step S200 by using the data related to the key distributed in the step S100(S300); demanding the related data for setting the pairwise key and the node included in other clusters among the neighboring nodes grasped in the step S200(S400); and setting the pairwise key by using the related data(S500).
