IoT METHOD AND SYSTEM FOR AUTHENTICATING TOKEN FOR IoT DEVICE BASED ON PRIVATE BLOCKCHAIN

摘要

The present disclosure provides a token authentication and authorization system for a private blockchain-based IoT device. The system includes a front-end unit including a user interface for receiving at least one of a user registration request, a user authentication request, and a device authentication request inputted from a user terminal, and outputting a result of executing the request, and from the front-end unit and a backend unit that receives the request and executes at least one of user registration, user authentication, and device authentication. The backend unit provides a plurality of blockchain nodes including a smart contract capable of executing user registration, user authentication and device authentication, and an API (application programming interface) for executing the user registration, user authentication and device authentication. an API node, wherein, in response to the request, the API node provides an execution result of at least one of the user registration, user authentication, and device authentication using the API.
