Power Data Blockchain Sharing Scheme based on Homomorphic Encryption

In the process of cross-agency flow of power data, only sharing the results of the operational analysis of power data rather than the source data is an effective sharing method that can not only meet the needs of data value mining, but also prevent source data leakage and protect data rights and interests. Hence, a power data blockchain sharing scheme based on homomorphic encryption was proposed, which making the data sharing rules and computing trustworthiness with smart contracts, and prevented data leakage with homomorphic encryption algorithms. Further, a power data sharing platform based on the sharing scheme was built and designed with Hyperledger Fabric as the underlying blockchain framework, so that the power data would be computed credibly in the chain code Docker container environment. Finally, our work simulated the sharing scheme with two-node deployment on one device. The response performance of the sharing operation tested by Hyperledger Caliper shows the superiority of our design.
