A Pre-assigned Key Management Scheme for Heterogeneous Wireless Sensor Networks
The studies on key management mostly are focusing on Heterogeneous Wireless Sensor Networks (HWSN), since the security problem of HWSN is complex due to different functions of nodes. In order to solve this problem, a pre-assigned key management scheme combining Schnorr authentication is proposed for HWSN in this paper based on the asymmetric method. Simulation results show that, compared with traditional key management scheme, the proposed scheme can not only enhance the network security but reduce the storage requirements.
