Abstract: In order to identify manipulations of cyber-physical-systems, in which the manipulations of the cyber-physical-systems, such as cyber-security attacks or manual attacks, can be identified in real-time in order to avoid or even prevent damages to the cyber-physical systems, it is proposed with regard to (i) a cyber-physical-system (CPS, CPS') with an embedded, distributed and complex system structure (SST) and providing sensor/actor-signal-information (SASI) depicting a behavior of the cyber-physical-system (CPS, CPS') during operation or commissioning, and (ii) a Digital-Twin-Unit (DTU), which in the course of "Model-based Digital-Twin-Representation" of the cyber-physical-system (CPS, CPS') creates and executes a digital twin (DT) replicating the behavior of the cyber-physical-system (CPS, CPS') and consequently producing replicated sensor/actor-signal-information (SASIrp) by simulating the cyber-physical-system (CPS, CPS'), and when the cyber-physical-system (CPS, CPS') and the Digital-Twin-Unit (DTU) are run in parallel, (1) to detect cyclically a deviation in the behavior of the cyber-physical-system (CPS, CPS') by comparing information by information the sensor/actor-signal-information (SASI) with the replicated sensor/actor-signal-information (SASIrp), (2) to identify a manipulation of the cyber-physical-system (CPS, CPS') if - for each detection cycle the sensor/actor-signal-information (SASI) and the replicated sensor/actor-signal-information (SASIrp) are different and consequently the deviation is detected, and - the detected deviation exceeds a threshold or tolerance value (TV).
