A strategy for wireless sensor network security is presented through dividing sensing multi-dimension hypercube into clusters and using the overlap key sharing (OKS) concept in this paper.The multi-dimension sensing hypercube is divided into a number of small same dimension hypercubes called cells, some of which are comprised of a cluster called logical group.The overlap key sharing protocol creates long bit clusters as the key cluster pools and distributes a sub-group to every sensor as key cluster.Analysis and comparison demonstrate this scheme enhances the WSN security, realizes the flexile secure grades for WSN, and has good network connection. Location-based pairwise key establishmentBit cluster group establishment and sensing hypercube division.In this paper, the sensing space is a d n dimension, 1 D , 2 D , , 1 d n D -, and d n D , hypercube denoted as hc V and the nodes are equally distributed in hc V in this scheme.We introduce the key cluster concept in paper [3].In [3], the overlap key sharing protocol creates long bit clusters as the key cluster pools and distributes a sub-group to every sensor as key cluster.The sensors employ the overlap sections as the sharing keys with their neighbor sensors.
