Abstract

The Internet of Things (IoT) access control mechanism may encounter security issues such as single point of failure and data tampering. To address these issues, a blockchain-based IoT reputation value attribute access control scheme is proposed. Firstly, writing the reputation value as an attribute into the access control policy, and then deploying the access control policy in the smart contract of the blockchain system can enable the system to provide more fine-grained access control; Secondly, storing a large amount of resources from the Internet of Things in Inter Planetary File System (IPFS) to improve system throughput; Finally, map resource access operations to qualification tokens to improve the performance of the access control system. Complete simulation experiments based on the Hyperledger Fabric platform. From the simulation experimental results, it can be seen that the access control system can achieve more fine-grained and dynamic access control while maintaining high throughput and low time delay, providing sufficient reliability and security for access control of IoT devices.
