Abstract

This paper explores and evaluates a dedicated setup process for appliances connected to the Industrial Internet of Things (IIoT). These differ significantly from classic IoT devices because they often need certified and highly specialized labor for installation and follow an inherently different life cycle. The emphasis lies on the configuration of devices using Bluetooth Low Energy (BLE) highlighting the challenges in establishing secure and efficient communication practices between the actors in the configuration procedure. The derived protocol is implemented prototypically using off the shelf hardware components (Raspberry Pi, ESP32) and standardized encryption components used by internet services. A crucial part is determining if desktop grade encryption can be used to secure connection with embedded devices having significantly less computing power than classic computer equipment. An important focus point is the design fitting a broad range of infrastructure (wireless/wired) and providing a template to adapt the protocol for existing applications.
