Security based design space exploration for CPS

Security is vital for Cyber-Physical Systems (CPS). CPS have become important in the industry, as they are often used to process sensitive data. Hence, they are valuable targets for attackers. As they are subject to manifold constraints, such as performance, power dissipation, etc., and security measures always induce additional delay, energy consumption, etc., designing secure CPS is a complex task. To find an optimal solution considering these various constraints, a design space exploration (DSE) must be performed. In this paper, we present a framework, capable of considering security constraints described as attack scenarios and automatically selecting appropriate security measures and secure key placement. We show the framework's feasibility by designing a secure sensor system.
