Fuente: Wipo "IOT" The present invention relates to a method of authenticating an Internet of things (IoT) device and verifying integrity of the IoT device and a control device using the same. The method of authenticating an Internet of things (IoT) device and verifying integrity of the IoT device and the control device using the same comprise the following steps of: (a) allowing the control device to obtain an authentication transaction from a blockchain network, or obtain IoT device identification information and at least one IoT device detailed information from the IoT device and obtain a verification transaction from the blockchain network when a triggering condition for authenticating the IoT device or verifying integrity of the IoT device is satisfied in a state in which the verification transaction is registered in the blockchain network; and (b) performing a process of verifying the integrity of the IoT device by comparing comparison target verification information with verification information obtained from the verification transaction.
