Security key management is the most basic requirement for wireless sensor networks security. In this paper, we propose a dynamic key management scheme for large-scale clustering wireless sensor networks based on improved EBS. We use two one-way hash chains for nodes registration and verification, take half-symmetric t-degree trivariate polynomial keys to replace the original keys used in EBS, and improve EBS making it eject more than one node simultaneously. Analysis and performance evaluations show that the proposed scheme improves the resistance to node capture, node masquerade and collusion attack, reduces energy consumption during rekeying and node ejection, is suitable for large-scale clustering wireless sensor networks.
