【摘要】 信息物理融合系统(Cyber-Physical System,CPS)是信息系统与物理系统紧密融合一体化的复杂系统,通过环境检测并将计算、通信、控制过程高效结合,实现对物理世界实时感知和动态控制的功能。CPS是继互联网之后的又一场信息革命,而安全问题是决定CPS能否被广泛使用的关键因素之一。文章首先阐述了CPS的安全要求、安全目标和面临的安全挑战,接着具体讨论了在物理层、传输层、应用层这三个层次所面临的攻击方式,然后重点分析了CPS在抗攻击技术、身份认证技术、隐私保护技术和风险评估技术等方面的研究现状,最后对CPS的安全研究进行了展望。

【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.
