Key distribution is the key problem in wireless sensor network security.In the traditional key management scheme,after the shared key is established between sensor nodes,the sensor node energy consumption is imbalance,the total network is unsecure.In order to improve network security,the network key management is proposed based on energy balance.First,according to the energy of the sensor nodes,several non-intersect paths are established among the source and the destination sensor nodes.Then base on the minimum and maximum energy transfer theory,an optimal sensor node non-intersect path between the source and destination sensor nodes is established as the consulting channel of path key.Simulation results show that,compared to the traditional key management schemes,this poposed scheme enables network energy more balanced,and improves the safety of network.Therefor,tt is a low energy consumed and good security key management scheme.
