Hierarchical secret sharing system is proposed based on the identity of the Ad hoc group key managementscheme.Based on lattice theory,all the patch elements of the bounded distributive lattices constitute a sub-lattice.All the ele-ment and patch element are divided into ordinary node and service node in the distribution lattice.The shares held by servernodes include more information than that held by ordinary nodes.The scheme can reduce the risk of distributing key equiva-lently to all nodes which may lead the group key to be renewed if any K nodes are attacked.The logical structure of thescheme is a grid.This scheme not only has the advantages of high connectivity and low load,but also has high expandability.By using the network simulator Opnet simulation results show that this scheme is more efficient,secure and stronger anti-at-tack than traditional scheme.
