Granular Access Control of Smart Contract Using Hyperledger Framework

The blockchain is an emerging technology and is used in various applications for data security and trustworthiness. One fundamental technique of blockchain is that any changes incorporated by the authorized user in the system have been inserted into the transaction and would be traceable. The smart contract access control mechanisms have gained considerable attention since its applications. However, there are no systematic efforts to analyze existing empirical evidence. To this end, we aim to synthesize literature to understand the state-of-the-art of smart contract-driven access control mechanisms concerning underlying platforms, utilized blockchain properties, nature of the models, and associated test beds and tools. The attribute-based access control access rights are granted to users by evaluating suitable attributes. An essential aspect of access control is to preserve the user’s identity accessing a service. This paper’s objective is to propose an access control mechanism of smart contracts to ensure that only authorized users can access the authorized component of the object in the Hyperledger framework.
