Secure Resource Sharing on Hyperledger Fabric based on CP-ABE
Shu Liu, Yanlei Shang · 2021
Nowadays, Web services are becoming more and more common in people's lives. However, resources and services are coupled on the Web. That's to say, users have to expose their data to service providers in order to trade for Web services. Consequently, users lose control to their personal data, and undertake the hazard of data abuse and privacy leakage. Distributed resource sharing systems are dedicated to solving this problem, which typically face huge challenges in terms of access control mechanisms and data availability. Blockchain-based methods provide an effective solution, but mining consumes large computing power overhead and the accomplishment of access control mechanism is incomplete. In view of the above-mentioned challenges encountered in distributed resource sharing systems, we design a secure resource sharing architecture based on Hyperledger Fabric, and established a dedicated network and consensus mechanism to avoid unnecessary energy costs. We developed a fine-grained access control implementation plan for both acquisition and modification operations to flexibly realize the users’ unconditional control over personal data. We implemented a software prototype to verify the effectiveness of the proposed architecture.
