The integration of cyber technologies (computing and communication) with the physical world gives rise to complex systems referred to as Cyber Physical Systems (CPS), for example, manufacturing, transportation, smart grid, and water treatment. Many of those systems are part of the critical infrastructure and need to perform safely, reliably, and securely in real-time. CPS security is challenging as compared to the conventional IT systems. An adversary can compromise the system in both the cyber and the physical domains. However, the unique set of technologies and processes being used in a CPS also bring up opportunities for defense. CPS security has been approached in several ways due to the complex interaction of physical and cyber components. In this work, a comprehensive study is taken to summarize the challenges and the proposed solutions for securing CPS from a Physics-based perspective.

CPS 安全的挑战与机遇：基于物理学的视角

网络技术（计算和通信）与物理世界的集成产生了称为网络物理系统 (CPS) 的复杂系统，例如制造、运输、智能电网和水处理。其中许多系统是关键基础设施的一部分，需要安全、可靠和可靠地实时运行。与传统 IT 系统相比，CPS 安全具有挑战性。对手可以在网络和物理领域破坏系统。然而，CPS 中使用的一组独特的技术和流程也为防御带来了机会。由于物理和网络组件的复杂交互，CPS 安全已通过多种方式实现。在这项工作中，
