Fast Convergence Algorithm on Pairwise Key Path in Sensor Networks
WU Jiayin · Jisuanji gongcheng · 2006
The pairwise key scheme,which enables any two nodes to share a common key,plays a key role in sensor networks security.Due to node resource constraints,research focuses on achieving minimum path length of indirect pairwise key construction.A fast algorithm on pairwise key establishment is presented,based on the hypercube model.The improved algorithm can effectively reduce the number of different bits between any two nodes by means of subsection on binary strand and boolean calculation,thus evidently reduces the number of intermediate nodes on created key path.
