Zusammenfassung / Abstract

In this work, novel security functionalities for Industrial Radio Systems (IRSs) are proposed. IRSs are of high relevance to modern societies, as they enable efficient manufacturing across essential sectors such as food, healthcare, and transportation. They comprise a wireless communication subsystem and industrial applications (e.g. robot arms or production lines). However, the open nature of wireless communication channels makes these systems prone to cyberattacks, necessitating adequate security measures under stringent Quality of Service (QoS) constraints. Such measures include enhanced security architectures, key management, and secure data transmission mechanisms.

On the architectural side, the concept of automated Plug&Trust (P&T) protocols is introduced to support secure device onboarding and automated security management in IRSs. Furthermore, security solutions tailored to Machine Type Communication (MTC) requirements based on Physical Layer Security (PLS) are proposed and evaluated. For Ultra-Reliable Low-Latency Communication (URLLC), lightweight Physical Layer Authentication (PLA) schemes based on supervised machine learning are developed. These approaches achieve high authentication performance even in complex environments, thus enabling secure URLLC message transmission. For massive MTC, Secret Key Generation (SKG) schemes based on PLS are developed and validated. The use of autoencoder-based reciprocity enhancement, multi-bit quantization, and pre-filtering significantly improves the key generation rate under given bit disagreement rate constraints.

Overall, the results demonstrate that the proposed solutions effectively enhance security in IRSs while maintaining system performance and meeting industrial QoS requirements.
