Data Privacy Protection and Sharing in Smart Grid Based on Blockchain Technology

Abstract

With the rapid development of science and technology, the scale of power grid construction is gradually expanding, and the level of intelligence is also constantly improving, which also brings the problem of data leakage and data loss to the smart grid. In response to the data loss and leakage problems in the smart grid, this paper proposes a blockchain-based data privacy protection and data sharing protection system. This system integrates encryption algorithms and corresponding sharing mechanisms in distributed data storage, which not only effectively improves the storage capacity of data but also enhances the security of data storage to a certain extent. Test results show that the system can achieve fast encryption of datasets, and the encryption scheme has certain authenticity and non-forgeability, which can further enhance the security of data storage and sharing. It plays a very important role in improving the security level of smart grid operation.
