System security requires communication credentials to be unique for each device and securely stored, which raises challenge for massive device provisioning. Here, we present how to create a factory device provisioning flow, the method that is integrated with a device manufacturing process. Our solution consists of two main components. Namely, custom scripts that allow generating device credentials for large batches of devices and integration of Zephyr mechanisms for enabling secure credentials storage. The latter is based on NVS and Settings subsystems. Our secure storage solution is applicable to all Zephyr compliant hardware platforms, as a result of using Zephyr's device abstraction. The presented solution is published as a Zephyr extension and allows for massive device provisioning to Microsoft Azure and AWS clouds as well as to Coiote IoT DM, our device management platform."
