IoT Device Provisioning Sequence
How a new device joins the platform securely: claiming by the owner, certificate issue and its first connection to the MQTT broker.
Drawing diagram…
What this diagram shows
- Owner claims the device with a code printed on it
- Device gets its own X.509 certificate
- Broker only accepts connections with a valid certificate
Prompt used
Sequence for provisioning a new IoT device: the owner scans the claim code in the mobile app, the provisioning service links the device to the owner's account in the device registry. When the device first boots it sends a certificate signing request, gets an X.509 certificate from the certificate authority, connects to the MQTT broker with mutual TLS and publishes its first status message.
