  • System for IoT devices communicating with server using a tentative common key
    Patent number: 11178137
    Abstract: A data communication system has an IoT device, an information processing device capable of performing communication with the IoT device, and a server capable of performing communication with the IoT device and the information processing device. When a coupling request from the IoT device is received, the information processing device requests the server for a tentative common key which is temporarily valid. When a request for a tentative common key from the information processing device is received, the server generates a tentative common key and transmits the tentative common key to the information processing device. The information processing device transmits the received tentative common key to the IoT device, and the IoT device and the server perform authentication by using the tentative common key.
