An Efficient Secure Key Management Scheme based on Secret Sharing for Hierarchical Wireless Sensor Networks
Tamer Mohamed Barakat · 2015
Wireless sensor networks (WSNs) have acquired a lot of interest due to huge number of applications. If WSNs are deployed in inimical ambience, the nature of sensor nodes must be considered such as the limitation of memory resources, low computation ability, short communication range and energy constraints. So that it is necessary to use an efficient and secure key management scheme to avoid the mentioned limitation issues as well as to reduce the security risk. In this paper, we propose an Efficient Secure Key Management scheme (ESKM) based on secret sharing scheme which address the above problems. The proposed scheme generates three security keys; master, cluster, and sensor keys to provide secure data communication for whole nodes in the hierarchical structure of WSNs. Compared to other key management schemes; ESKM scheme has strong security and resistance against captured and forward secrecy attacks. Finally, the simulation results show that, ESKM scheme has low energy consumption, less key storage and low communication overhead compared to the existing key management schemes.
