一种支持完整性验证的隐私保护直方图融合算法
A Privacy Preserving Histogram Aggregation Algorithm with Integrity Verification Support
摘要
Abstract
Towards the fact that it is difficult to provide privacy protection and integrity verification simultaneously in data aggregation ,we propose a privacy preserving histogram aggregation (iPPHA ) algorithm with integrity verification support .It con-structs two aggregation trees to transmit aggregate data and redundant information separately .It lets the sink use the redundant infor-mation to verify the integrity of the aggregation result .Considering the packet loss problem in WSN ,we design an ID transmission scheme flexible bit-map to ensure the reliability of privacy preserving data aggregation and integrity verification .The simulation re-sults show that iPPHA can verify data integrity while protecting data privacy without dramatic resource consumption increase .Flexi-ble bit-map scheme significantly reduces the ID transmission overhead by 70 percent .关键词
