英文摘要：

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.
