An Efficient and Hybrid Key Management for Heterogeneous Wireless Sensor Networks

摘要：

　　Key management is the core to ensure the communication security of wireless sensor network.How to establish efficient key management in wireless sensor networks(WSN)is a challenging problem for the constrained energy,memory,and computational capabilities of the sensor nodes.Previous research on sensor network security mainly considers homogeneous sensor networks with symmetric key cryptography.Recent researches have shown that using asymmetric key cryptography in heterogeneous sensor networks(HSN)can improve network performance,such as connectivity,resilience,etc.Considering the advantages and disadvantages of symmetric key cryptography and asymmetric key cryptography,the paper propose an efficient and hybrid key management method for heterogeneous wireless sensor network,cluster heads and base stations use public key encryption method based on elliptic curve cryptography(ECC),while using symmetric encryption method between adjacent nodes in the cluster.The analysis and simulation results show that the proposed key management method can provide better security,prefect scalability and connectivity with saving on storage space.
