With the rapid development of smart grids, the secure sharing and auditing of power data has become increasingly important. However, the traditional access control threshold for power data is low and cannot guarantee the privacy security and integrity of the data. Therefore, a secure storage, access and auditing scheme for power data combining blockchain technology and attribute encryption is proposed. Firstly, the encrypted storage and authorized access of the data are achieved through the collaborative work of the key distribution centre and the data authorization authority, and the integrity and availability of the data are ensured through the auditing of the power data. In addition, the application of smart contracts further automates the access control process, enabling data visitors to efficiently access the required data after authentication. The security analysis shows that the scheme provides integrity checking of power data while protecting the privacy of datapower. Performance evaluation shows that the scheme has low computational overhead and storage overhead compared to the existing state-of-the-art schemes.
