Embodiment 1
[0052]Such asimage 3As shown, Embodiment 1 of the present invention proposes an IoT gateway system. The system includes a gateway processing module set on the gateway device, a smart speaker with the gateway device in a local area network, a key management module set on an external network server, and an external network service processing module. This embodiment takes a single voice-controlled smart speaker as an example for description.
[0053]1. Gateway initialization: The gateway will have a built-in gateway device key in the hardware encryption chip when it leaves the factory, and the key management module is entered at the same time when it leaves the factory. This operation is carried out inside the factory, so it will not be transmitted on the external network. Except for the key management module, this key data cannot be obtained outside the device. Therefore, the security of the key itself can be guaranteed;
[0054]2. The smart speaker establishes a session and a secure sessio...
Embodiment 2
[0061]Embodiment 2 of the present invention proposes an IoT gateway system. The system includes a gateway processing module set on the gateway device, a smart speaker in a local area network with the gateway device, a key management module set on an external network server, and external Internet service processing module, and mobile phone; this embodiment uses the mobile phone to transmit audio files to the smart speaker as an example for description.
[0062]1. Gateway initialization: The gateway will have a built-in gateway device key in the hardware encryption chip when it leaves the factory, and the key management module will be entered at the same time when it leaves the factory. This operation is performed inside the factory, so it will not be transmitted on the external network. Except for the key management module, this key data cannot be obtained outside the device. Therefore, the security of the key itself can be guaranteed;
[0063]2. Mobile phone device initialization: The sec...
Embodiment 3
[0075]Due to the wide variety of IoT devices from different manufacturers, the IoT devices of this system support the following two types:
[0076]1. It is in the same secure local area network as the gateway, and some need to install the Internet of Things service processing module; it is used to send a request to the gateway device to obtain external network service data;
[0077]2. Some external network devices can also be connected to the gateway, such as positioning watches, etc. This part of the device needs to have a built-in "Internet of Things Device Key", which is similar to the gateway key function, and the user can obtain a secure Session key. Other processing procedures are the same as those in Embodiments 1 and 2, and will not be repeated here.
[0078]The design idea of the present invention is:
[0079]Internet of Things devices (such as smart speakers) are connected to the gateway through protocols such as LAN / Bluetooth, and the Internet of Things devices need to interact wit...
