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.
