Abstract:

A cyber-physical system (CPS) is a complex system which integrates information systems with physical systems. It realizes the function of real-time sensing and dynamical control of the physical world by environment perception and the integration of computing, communication and control process. CPS is viewed as the next information revolution after the Internet and security problem is one of the key issues affecting the wide application of CPS. This paper introduces the requirements and goals of CPS security, as well as security challenges that a CPS faces. Attacks on a CPS from physical layer, transport layer and application layer are also discussed in detail. By analyzing current research on techniques of anti-attack, identity authentication, privacy preservation and risk assessment in CPS, the paper discusses the future research trends in this area.

Key words: cyber-physical system (CPS), internet of things (IoT), industrial control system (ICS)
