A novel secure scheme for wireless sensor networks
Yuquan Zhang, Wei Lei · 2010
A pairwise key establishment scheme based cells and logical groups is presented in this paper through utilizing the overlap key sharing (OKS) concept. The sensing cube is divided into a number of small cubes, eight of which consist of a logical group. Analysis and comparison demonstrate our mechanism has a good resilience against node capture, realizes flexible secure grades, and has good network connectivity.
