摘要
Data sharing serves to maximize the efficiency of data resources by facilitating their full utilization and reducing associated costs. However, existing data-sharing schemes are confronted with issues such as data loss, data tampering, difficulties in privacy protection, and high sharing costs. To address these issues, this paper proposes a blockchain-based security-oriented data-sharing scheme. Firstly, an architecture that separates data from data ownership is employed to enhance the security of the scheme and reduce storage overhead. Secondly, a lightweight on-chain and off-chain collaborative data security algorithm based on ECC and ECDHE is designed to ensure confidentiality during data sharing. Finally, a mechanism for tracking the circulation of shared data is proposed, which records the data flow in non-fungible tokens (NFTs), thereby improving the traceability of the proposed scheme. We designed relevant experiments to evaluate the proposed solution, and the results demonstrate that the data-sharing scheme devised in this paper performs well in terms of both security and usability, effectively achieving secure data sharing.
