Abstract:
Virtualized automation functions can be used in a cyber-physical system to influence the real, physical world using sensors and actuators connected via input-output modules. Other virtualized automation functions may be used for planning, testing, or optimization. It has to be distinguished reliably which instances in fact interact with the real, physical world, and which ones are used for other, less critical purposes. A reliable method for determining whether a certain virtualized automation function has access to the real, physical world is proposed, based on a cryptographically protected physical-world access attestation issued by an input/output module. It confirms whether a certain virtualized automation function has in fact access to the real-physical world.
