Abstract: The current data sharing schemes mainly employ Attribute-Based Encryption (ABE) technique to achieve oneto-many access control for power data.However, these schemes suffer from issues such as low encryption efficiency and vulnerability to user attribute tampering.To address these problems, a power data sharing scheme based on multi-strategy access trees is proposed.By combining ABE with symmetric encryption algorithms, specifically employing the Advanced Encryption Standard (AES) in conjunction with Ciphertext-Policy ABE (CP-ABE), a hybrid encryption mechanism is adopted.Building upon an encryption algorithm rooted in multi-strategy access trees, data visitors are categorized into security levels according to roles and regions.Then, a time-constrained attribute encryption scheme is proposed for designated personnel, thereby achieving confidentiality and fine-grained access control for power data.Analysis results indicate that the proposed scheme enables secure sharing of power data and is highly suitable for resource-limited power terminal devices.
