Abstract

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
