Abstract The current access control of IoT devices adopts the traditional method of centralized control, which leads to the shortcomings of single point of failure and low efficiency of the entire system. Due to the increasing amount of data generated by the Internet of Things network and the more complex data structure, the traditional access control system has exposed the problem of insufficient security when communicating. Based on the characteristics of blockchain decentralization, non-tampering, and programmable Hyperledger, an attribute-based access control mechanism combining blockchain with the Internet of Things is proposed to realize dynamic changes to the access control strategy and ensure the access control of the Internet of Things Safety and reliability.
