Routing based two-level key management scheme in wireless sensor networks

On the basis of the existing tree-based key pre-distribution schemes,this paper proposed a new hierarchical key management scheme in combination with the routing topology in WSN.Considering different communication requirements among sensor nodes,the inter-cluster protocol took re-encryption and authentication mechanisms while the intra-cluster assigned an administrative node for generating and maintaining the routing key tree.The results show that this new scheme can highly achieve secure and efficient data transmission.
