Abstract
In this paper, we propose a new privacy-preserving scheme for access control in IoT based on blockchain technology and role-based access control (RBAC). The decentralized property and reliability of the blockchain platform make the proposed solution fit the geographically distributed scenario for IoT better. We extend the traditional RBAC with a new device domain to realize more flexible and manageable access control for the diverse IoT devices. Besides, the scheme takes advantage of zero-knowledge proof and the trusted execution environment (TEE) to ensure the transaction information is confidential, to protect the privacy of the details of access control including information of roles, devices, and policies. To demonstrate the feasibility and effectiveness of the architecture, we implemented our scheme and evaluated on the Ethereum private chain to achieve privacy-preserving access control for IoT. The results show that our scheme is feasible and the cost is acceptable.
