A Privacy-Preserving Data Sharing Framework for Smart Grid

A Privacy-Preserving Data Sharing Framework for Smart Grid
Distributed energy resources, featured with small scale power generation technologies and renewable energy sources, are considered as necessary supplements for smart grid. To ensure that merged resources contribute effectively to the grid, data generated by consumer side should be shared among the energy resources. However, it also introduces challenges of the protection of consumer privacy. To address these difficulties, a new framework is proposed to share data in smart grid by leveraging new advances in homomorphic encryption and proxy re-encryption. Proposed framework allows energy resources to analyze consumer data while ensuring consumer privacy. An additional benefit of our proposed framework is that consumer data is transmitted over the smart grid only once.
