Abstract
Security is an increased concern in smart manufacturing, however, is often met with concerns from operational technology (OT) operators. Performance is paramount in OT communication and, thus, a higher risk is currently deemed acceptable. However, the probability for cyber attacks is rising as recent, successful attacks on factory communication demonstrate. In this work, we present a performant security protocol extension for usage in OT networks. It enables message authentication and data integrity while keeping the protocol overhead within real-time constraints. The protocol extension protects against attacks targeting communication of cyber-physical systems in a smart manufacturing environment. The availability of OT operations facing these attack vectors is, thus, guaranteed.
