A Security and Safety Framework for Cyber Physical System

Cyber-Physical System (CPS) is a system that integrates physical system with cyber capability in order to improve the physical performance [1]. Up to now, it has been widely applied in people´s daily lives. After research and discussion in recent years, we believe that most researchers already have a comprehensive understanding about CPS. This paper systematically introduced CPS´s conception, development and applications assisted with pictures. In addition, concerning about the safety and security aspects, we analyze CPS´s risks and new requirements as an up-to-date technique brings. We also elaborate the existing work and propose a research focus and idea that have not been paid enough attention to. At last, we provide a classic modeling and simulation method of CPS, and bring forward a new idea for accessing the experimental results into existing systems.
