IoT BLOCKCHAIN-BASED RAPID ACCESS CONTROL SYSTEMS AND METHODS FOR THE IOT DEVICE

摘要

The present invention relates to a blockchain-based high-speed authentication control system and method for controlling IoT devices. The system provides an IoT device that transmits a user identifier and command data in response to a user's request for a control command, based on the user ID and command data transmitted from the IoT device, and access control data synchronized from a blockchain platform, a control command An access control device that processes authentication and authorization by determining whether a user who has requested a request has control authority over the IoT device, and a block chain platform that periodically synchronizes and updates the access control device, the access control device comprising: The access control data including an applicable user identifier and a control command set for each user are periodically received from the block chain, synchronized, updated, and stored, and the control command of the IoT device has a plurality of function-specific control commands, Each control command has policy data, each policy data has at least one rule data, and the access control data includes a plurality of control commands for one IoT device, a policy data group associated with each control command, and the policy data It is characterized in that it includes a group of rule data associated with the group. Accordingly, real-time precise control of the IoT device is possible because the access control device performs authentication, authorization, and control processing of the user who wants to control the IoT device, and data integrity by storing the access control data in the block chain platform can be obtained
