中文摘要：

为了减少高级量测体系（AMI）中无线传感器网络（WSNs）的数据传输量、提高传输效率、延长网络寿命，提出了一种基于数据可恢复的安全数据聚合方案。所提方案基于同态加密算法对采集数据进行加密、聚合操作，以确保数据的机密性，并基于一种合理的编码机制准确恢复各采集数据。为了确保数据传输的完整性，提出了一种基于中国剩余定理（CRT）的验证机制。通过分析聚合方案的性能，验证了所提方案具有较强的安全性，且只需较少的计算消耗和通信消耗。

英文摘要：

A security data aggregation scheme based on the data recoverability is proposed to reduce the data transmission capacity of the wireless sensor network of AMI（Advanced Metering Infrastructure）,improve its transmission efficiency and prolong its lifetime ,which encrypts and aggregates the acquired data based on the homomorphic encryption algorithm to ensure the data confidentiality and accurately recovers them based on a reasonable encoding mechanism. An authentication mechanism based on the Chinese remainder theorem is proposed to ensure the integrity of data transmission. The performances of the proposed scheme are analyzed to verify its higher security and less computation and communication costs.
