摘要：

智能电网能够利用用户实时用电信息对电网运行状态进行有效监控和预测,成为近年来电网技术的研究热点之一。然而在对实时用电信息进行分析和处理的同时也会带来用户隐私泄露问题。为了解决用户数据隐私保护的问题,文章基于前人研究的基础提出了新的分布式数据聚合模型,该分布式数据聚合模型在不需要增加聚合器的前提下达到数据离散化存储的目的,增加分析用户行为信息的难度。文章基于分布式数据聚合模型,提出一种新的隐私数据聚合协议,并采用同态加密与数字签名相结合的加密技术来保护用户用电数据的机密性和完整性。文章最后对提出的方案进行了安全性和有效性分析,分析表明该方案可以达到有效进行数据隐私保护的目的,能够提高智能电网数据传输的完整性和保密性。

Abstract:

Smart grid can make use of users’ real-time electricity consumption information monitor and forecast the operation conditions effectively, and has been one of the hotspots of grid technologies. However, the analysis and processing of their real-time electricity consumption information can result in users’ privacy leaking. In order to solve the problem of user data privacy protection, this paper proposes a new distributed data aggregation model based on previous studies. The distributed data aggregation model can achieve the purpose of data discretization and increase the difficulty of analyzing users’ behavior information without increasing other aggregators. Based on the idea of distributed data aggregation, this paper puts forwards a new privacy data aggregation protocol and employs the encryption technique, combining the homomorphic encryption and digital signature, to guarantee the confidentiality and integrality of users’ data. The authors have analyzed the security and effectiveness of the protocol in this paper. The result demonstrates that the scheme can achieve the goal of data privacy protection effectively and improve the integrity and confidentiality of data transmission in the smart grid.

Key words: smart grid, privacy protection, distributed data aggregation, homomorphic encryption
