MQTT(S) Certificate Authentication

MQTT(S) Certificate Authentication
Introduction
MQTT(S) certificate authentication requires you to upload a device CA certificate on the console first. Then, you can either use the API for creating a device or register the device on the console to get the device ID. When the device accesses the IoT platform, it carries the X.509 certificate for authentication, which is a digital certificate used to authenticate the communication entity.
Constraints
- Only MQTT devices can use X.509 certificates for identity authentication.
- You can upload up to 100 device CA certificates.
Procedure
Figure 1 MQTT(S) certificate authentication process
- A user uploads a device CA certificate on the IoTDA console.
- An application calls the API for creating a device to register a device. Alternatively, a user uses the IoTDA console to register a device.
NOTE:
During registration, use the MAC address, serial number, or IMEI of the device as the node ID.
-
The platform allocates a globally unique device ID to the device.
- During login, the device sends a connection request carrying the X.509 certificate to the platform.
- If the authentication is successful, the platform returns a success message, and the device is connected to the platform.
