Due to the bad resilience and large storage overhead of current schemes,this paper proposed a layered key management scheme for wireless sensor networks.Implementing the Blom-matrix in the cluster heads communication,it could effectively enhance the ability of the resilience.By means of the Chinese remainder theorem,it shifted the complexity to the base station lowering the storage consumption.Under comparative analysis,it meets the scenario of the WSNs key management and improves its security performance.
