摘要(Abstract)：

数据聚合在智能电网领域得到广泛的应用，保护数据隐私是数据聚合应用的一个重要问题.现有的方案存在计算开销大、实体对象身份未验证、过度依赖可信权威中心等问题.提出一种轻量级的隐私保护数据聚合方案.该方案首先采用基于双线性对的IDMAKE2协议对聚合器和智能电表进行身份验证；其次，利用加法同态加密算法加密电量数据保护用户的隐私.此外，方案不依赖于可信权威中心，并且可以抵抗内部实体对象间的合谋攻击.安全分析表明，能够满足智能电网的安全要求.性能分析实验中，和其他同类方案对比，仅需要较低的计算开销和通信开销.

关键词(KeyWords)： 智能电网;数据聚合;隐私保护;身份验证;合谋攻击
