Aiming at the problems that under the condition of large-scale deployment of wireless sensor network,clustering key management methods had contradictions in terms of safety,complexity and computational overhead,by using hash chain, q-composite key management scheme was improved and applied to clustering structure.A scheme based on clustering network hash chain was proposed.The scheme was easy to implement and excellently performed.The simulation results showed that this scheme had good large-scale network scalability,significantly improved the network anti-capture capabilities,and maintain a higher rate of security connectivity.
