A Combined Model of Secure Cyber-Physical Systems for their Design and Verification

Abstract

In this paper a combined model of secure cyber-physical systems for their design and verification is proposed. Within the framework of this model, a cyber-physical system is represented as a set of blocks with various properties and relationships between them. The main challenge in such model construction is to combine various approaches to the modeling of cyber-physical systems (or their elements) within a single approach. The main goal of the proposed modeling approach is to provide the ability to convert various models into each other without losing significant data about the elements of the system, as well as taking into account the emergent properties that arise in the process of their interaction. The correctness of the proposed model is validated by the example of its use for design and verification of access control system.
