Trust Establishment in Cooperating Cyber-Physical Systems

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 9588)


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. We propose an efficient synchronisation scheme for system integrity data, reducing network traffic as well as verification effort.
