Document Type and Number:
WIPO Patent Application WO/2023/098816
Kind Code:
A1
Abstract:
The embodiments of the present invention provide a device communication method and apparatus based on an MQTT protocol. The method is applied to an MQTT theme management server, and comprises the following steps: receiving a first message, which is reported by a controlled node, wherein the first message comprises a device ID of the controlled node; generating a random theme corresponding to the device ID of the controlled node, and returning the random theme to the controlled node; and authenticating a control node, and then sending the random theme to the control node, such that the control node and the controlled node perform MQTT protocol communication by means of the random theme. In the present invention, an MQTT theme of node communication is managed by means of an MQTT theme management server, and the MQTT theme is randomized, such that a malicious network node cannot monitor or interfere with node communication, thereby improving the communication security between nodes of an MQTT protocol network.
