Improving the Reliability of Anomaly Detection for Encrypted OPC UA Traffic over Private 5G
Song Son Ha, Florian Foerster, Henry Beuster +3
Open Platform Communications Unified Architecture (OPC UA) is increasingly deployed over private 5G networks in industrial environments, where end-to-end encryption prevents payloa…
Residual Observability and Attack Detectability in Encrypted OPC UA Traffic
Song Son Ha, Florian Foerster, Henry Beuster +3
OPC Unified Architecture (OPC UA) encryption conceals application-layer semantics and restricts intrusion detection to residual communication structure. Although machine learning-b…
Converging Safety and Security: IO-Link Wireless and OPC UA over 5G under prEN 50742
Henry Beuster, Thomas Robert Doebbert, Gerd Scholl
The integration of wireless communication technologies in industrial automation offers greater flexibility, but also exposes safety systems to a broader threat vector. Emerging reg…
Impact of Benign Connectivity Variations on Intrusion Detection for Encrypted OPC UA Traffic in Industrial Private 5G Networks
Song Son Ha, Florian Foerster, Henry Beuster +3
Machine learning (ML)-based intrusion detection systems (IDSs) are increasingly used to monitor encrypted industrial communication. However, their behavior under realistic private…
An Experimental Study of Machine Learning-Based Intrusion Detection for OPC UA over Industrial Private 5G Networks
Song Son Ha, Kunal Singh, Florian Foerster +4
Industrial deployments increasingly rely on Open Platform Communications Unified Architecture (OPC UA) as a secure and platform-independent communication protocol, while private Fi…
OPC UA for IO-Link Wireless in a Cyber Physical Finite Element Sensor Network for Shape Measurement
Henry Beuster, Lars-Michel Bretthauer, Gerd Scholl
This paper presents the integration of OPC UA as a communication protocol in a wireless sensor network and the associated companion specifications as a semantic template for an inf…
Measurements of the Safety Function Response Time on a Private 5G and IO-Link Wireless Testbed
Henry Beuster, Kevin Tebbe, Thomas Doebbert +1
In the past few years, there has been a growing significance of interactions between human workers and automated systems throughout the factory floor. Wherever static or mobile rob…
Design and Development of a Roaming Wireless Safety Emergency Stop
Henry Beuster, Thomas Doebbert, Christoph Cammin +2
Modern manufacturing is characterized by a high degree of automation, with autonomous systems also frequently being used. In such environments human intervention in the event of ma…
Testbed for Functional Safety-Relevant Wireless Communication Based on IO-Link Wireless and 5G
Thomas R. Doebbert, Henry Beuster, Florian Fischer +2
In the field of industrial production automation, wireless networks support highly flexible manufacturing processes and enable technologies to set-up new production chains and futu…
