Summary:This application provides a key information synchronization method and system, and a device, and relates to the field of communications technologies. When a hub device manages an IoT device, a security risk and a risk of user privacy leakage during interaction between the hub device and the IoT device can be reduced. The method includes: A terminal sends a first public key of the terminal to an IoT device; the terminal obtains a second public key of the IoT device from the IoT device; the terminal sends first key information to a hub device, where the first key information includes a first private key of the terminal, the first public key, and the second public key; the hub device uses the first private key and the first public key in the first key information as a key pair of the hub device; and the hub device performs encrypted interaction with the IoT device by using the first key information.
