A localized key management for Wireless Sensor Networks
Min Li, Jianping Yin, Yongan Wu · 2010
LEBKM for Wireless Sensor Networks (WSN) is proposed in this paper, which employs the localized strategy. The key for each node is integrated from two keys separately provided by other two key managements. Once the nodes have been deployed, the localized strategy is adapted to update the pre-distributed keys in nodes within the same cluster. The resilience of the network is significantly enhanced by limiting the influence of node betrayal in a single cluster. LEBKEM is compared with other two schemes. The experiments and analysis show that LEBKM can achieve a better performance.
