Through the analysis of the privacy-preserving data aggregation algorithm(CPDA),this paper proposes a Key Management Scheme based on hierarchical cluster,which uses the logic structure of Binary-tree to organize the nodes and transmit slice data.In addition,we design a scheme to build the logical key binary tree by certain rules and can achieve privacy protection when data aggregate.Compared to CPDA,the analysis results show that our scheme can obtain higher privacy protection,lower communication overhead and better scalability.
