Abstract
Cooperating systems are systems of systems that collaborate for a common purpose. Cooperating cyber-physical systems often base important decisions on data gathered from external sensors and use external actuators to enforce safety critical actions. Using the example of a hydroelectric power plant control system, this paper analyzes security threats for networked cooperating systems, where sensors providing decision critical data are placed in non-protected areas and thus are exposed to various kinds of attacks. We propose a concept for trust establishment in cyber-physical cooperating systems. Using trusted event reporting for critical event sources, the authenticity of the security related events can be verified. Based on measurements obtained with a prototypical realisation, we evaluate and analyze the amount of overhead data transmission between event source and data verification system needed for trust establishment.
