“…Next, [32] combines the Hyperledger Fabric blockchain technology with the InterPlanetary File System (IPFS) [15], allowing IoT devices to easily store documents on a distributed file system and store the hashes of these documents on the blockchain ledger. Finally, [1] proposes a multi-layered and multi-model access control system in the context of an agricultural supply chain system that runs on Hyperledger Fabric.…”

“…While Bitcoin was created to provide a digital alternative to traditional, bank-controlled currencies [17], many of these newer blockchain technologies are designed to provide a platform for building and deploying decentralized applications through the use of smart contracts 1 . By implementing their business logic within these smart contracts, decentralized applications can automatically execute any transaction without human intervention, making them completely independent and decentralized [28].…”

This work aims to provide a more secure access control in Hyperledger Fabric blockchain by combining multiple IDs, attributes, and policies with the components that regulate access control. The access control system currently used by Hyperledger Fabric is first completely analyzed. Next, a new implementation is proposed that builds upon the existing solution but provides users and developers with easier ways to make access control decisions based on combinations of multiple ID's, attributes, and policies. Our proposed implementation encapsulates the Fabric CA client to facilitate attribute addition and simplify the process of registering and enrolling a newly created certificate (corresponding to a new user). This research, concludes that it is possible to combine multiple ID's, attributes, and policies with the help of Hyperledger Fabric's smart contract technology. Furthermore, it could be seen that the performance impact for real-world applications is negligible compared to the insecure case of always providing access to a resource without performing access control.Keywords: Blockchain • IPFS • Privacy • Security 1 A digital contract written into code that is stored and automatically executed on the nodes of a distributed blockchain network [6].
