Zero-touch provisioning of IoT devices with multi factor authentication

摘要

Techniques are disclosed for provisioning device-specific credentials to an Internet of Things device that accesses a cloud-based IoT service. The IoT service receives, from the IoT device, a request for device-specific credentials. The request comprises a provisioning certificate including information identifying a group of devices associated with the IoT device. The provisioning certificate is authenticated by evaluating the information with expected information. The device-specific credentials are generated based, at least in part, on the information provided in the provisioning certificate. The device-specific credentials are sent to the IoT device, and the IoT device installs and activates the device-specific credentials. The device-specific credentials are associated with the IoT device in a registry of the IoT service.
