摘　　要：提出了基于信源编码技术的无线传感器网络可恢复数据融合隐私保护方案.借助于节点数据相关性对隐私数据进行信源编码,实现了数据隐藏和压缩,对编码后的数据进行了形式转换和拼接,以进行原始数据的恢复,同时利用聚合签名技术鉴别数据的完整性.实验结果表明,该方案能在有效保护数据隐私性、减少数据传输量的基础上,实现对原始感知数据的恢复.Based on source coding technology,recoverable privacy-preserving data aggregation scheme for wireless sensor networks was proposed. The sensor data is hidden and compressed by source coding technology according to the correlation between them. Secondly,the coded data is converted and concatenated so that the base station can recover it. Meanwhile,the base station verified the integrity of data in accordance with aggregate signature. Experiment results demonstrate that the proposed scheme can realize the recovery of original data on the basis of protecting data privacy as well as decreasing redundant transmitted data.
