Embodiment 1
[0041] The communication method between IoT hardware and cloud described in this embodiment takes into account performance, safety and low power consumption. Its main communication methods include: HTTPS communication, which mainly involves product registration, product status reporting, firmware update, etc.; MQTTOVER TLS communication , which mainly involves the control instructions of smart products. HTTP communication mainly involves the interface of other information collection and reporting, the content is encrypted with AES, and anti-replay protection is carried out at the same time.
[0042] TLS channel encryption: With regard to TLS, the mandatory verification of certificates ensures that the channel is not easily hijacked. At the same time, the TLS component is used for tailoring, the hardware fixes the encryption method, and the code of the TLS component is optimized. The digital certificate chain level is fixed at 2 layers, reducing the consumption of hardware loa...
Embodiment 2
[0053] This embodiment provides a cloud communication device for the Internet of Things, including a memory and a processor memory for storing one or more computer instructions, wherein one or more computer instructions are executed by the processor to implement as described in Embodiment 1. The above-mentioned Internet of Things cloud communication method.
Embodiment 3
[0055] This embodiment provides a computer-readable storage medium, the computer-readable storage medium stores a computer program, and the computer program enables a computer to implement the IoT cloud communication method as described in the first embodiment.
[0056] Those skilled in the art can clearly understand that for the convenience and brevity of the description, the specific working process of the device described above can refer to the corresponding process in the foregoing method embodiment, and details are not repeated here.
[0057] Exemplarily, a computer program can be divided into one or more modules / units, and one or more modules / units are stored in a memory and executed by a processor to implement the present invention.
