Custom functions for device authentication

Before connecting a device to the platform, you can use the application to configure custom authentication information on the console, and then configure custom authentication functions by using FunctionGraph. When the device connects to IoT platform, the platform obtains parameters such as the device ID and custom authentication function name, and sends an authentication request to FunctionGraph. The user implements the authentication logic to complete access authentication.

Device certificates

For a device using MQTTS X.509 certificates, when it connects to the platform for the first time, IoTDA utilizes the uploaded and verified device CA certificate to authenticate the device certificate. After the authentication is successful, the platform automatically saves the device certificate. You can check and disable device certificates, and receive expiration warnings.

Automatic device registration

You can set a self-registration template, with which the device can connect to the platform without registering on the platform in advance. The platform parses the template content based on the device connection information and automatically registers the settings.

Stacked forwarding data clearance

When the rule engine forwards messages to a third-party application, if the application cannot process the data in real time, the data will be stacked on the platform. You can clear the data stacked in the forwarding channel for timely processing.

SMN notification templates for linkage rules

When setting a device linkage rule and selecting notification sending as the rule action, you can use the template defined by Simple Message Notification (SMN).

Authentication credential switchover

You need to update a device access credential in some scenarios, for example, when an X.509 certificate is about to expire. IoTDA provides master/sub fingerprints and secrets to prevent device authentication failure and service interruption during credential update and resetting. For example, when you add a new certificate fingerprint, the platform sets the fingerprint as a backup (sub fingerprint). In this way, the corresponding device can use both the old certificate (if not updated on the device side timely) and the new certificate to connect to the platform smoothly.

Device-side rules

Cloud rules are parsed and executed on the cloud. IoTDA determines whether triggering conditions are met and triggers corresponding device linkage actions. Device-side rules are device linkage rules delivered to devices, where the device-side rule engine parses and executes the rules. Device-side rules can still run on devices when the network is interrupted or devices cannot communicate with the platform.

Commercial use

Device-side rules

1

Rules

If the forwarding target (such as a third-party application server) cannot process data forwarded by IoTDA in a timely manner due to insufficient performance, unprocessed data will be stacked (cached) on IoTDA. By default, the maximum stack (cache) size of data to forward for a single forwarding rule is 1 GB, and the maximum stack duration is 24 hours. If the maximum stack size or stack duration is exceeded, the earliest unprocessed data will be discarded to meet the stack size and duration requirements.

Rules

You can create flow control policies in different dimensions on IoTDA based on your service scenarios and performance of the forwarding target (such as a third-party application server) to control data forwarding flows.
