摘要：Many key management schemes have been proposed in systematically deployed Wireless Sensor Networks (WSNs).The sensor nodes are equipped with inadequate battery power, low memory, limited computation and communication range. Energy efficient secure routing is major issue in wireless sensor networks. In this paper, the hybrid key management scheme is proposed by combining public key cryptography scheme with symmetric scheme. The symmetric keys are generated by using genetic algorithm. Initial input for the genetic algorithm is the seed key generated by Hyperelliptic Curve Cryptography (HECC).The proposed scheme addresses the energy efficiency, resilience against node capture attack, key refreshment between the cluster head and member nodes in the cluster. The simulation results show that the hybrid scheme is more robustness, efficient energy with reduced key size.
