Enhancing Cyber-Physical System Dependability via Synthesis: Challenges and Future Directions

Cyber-physical systems (CPS) rely on software that contains vulnerabilities and is connected to the public internet. Internet connectivity exposes CPS to adversaries, who can exploit vulnerabilities and cause CPS to operate in unsafe ways, thus compromising safety and liveness requirements. By formally designing safety and liveness requirements and synthesizing software that adheres to these specifications, unsafe behaviors can be prevented from the very beginning of system development. This paper presents initial results from ongoing research aimed at enabling the synthesis of software that controls CPS, ensuring dependability from the outset.
