Abstract

Existing healthcare data-sharing solutions often combine attribute-based encryption techniques with blockchain technology to achieve fine-grained access control. However, the transparency of blockchain technology may introduce potential risks of exposing access structures and user attributes. To address these concerns, this paper proposes a novel healthcare data-sharing scheme called HA-Med. By leveraging blockchain technology, HA-Med ensures the concealment of access policies and attributes, providing a secure solution for fine-grained access control of medical data. Furthermore, the scheme supports attribute revocation and forward secrecy to enhance user privacy. The security of HA-Med is rigorously verified through theoretical analysis, and its feasibility is demonstrated through experiments conducted using the Java-based JPBC library.

HA-Med：基于区块链的隐藏政策和属性医疗数据共享解决方案

现有的医疗保健数据共享解决方案通常将基于属性的加密技术与区块链技术相结合，以实现细粒度访问控制。然而，区块链技术的透明性可能会带来访问结构和用户属性暴露的潜在风险。为了解决这些问题，本文提出了一种名为 HA-Med 的新型医疗数据共享方案。通过利用区块链技术，HA-Med 确保了访问策略和属性的隐蔽性，为医疗数据的细粒度访问控制提供了一个安全的解决方案。此外，该方案还支持属性撤销和前向保密，以增强用户隐私。HA-Med 的安全性通过理论分析得到了严格验证，其可行性通过使用基于 Java 的 JPBC 库进行的实验得到了证明。
