AI总结：
本文综述30篇论文，将CPS对抗攻击恢复策略分为浅层与深度恢复，并结合探索性研究分析现状、空白与未来方向。
摘要：
近几十年来，信息物理系统（CPS）经历了快速增长。然而，与任何其他基于计算机的系统一样，恶意攻击也在协同演化，将CPS驱至不良的物理状态，并可能造成灾难。尽管当前最先进的研究已充分意识到这一问题，但大多数学者并未关注CPS恢复；我们将该过程定义为：在对抗攻击下，将CPS的物理状态恢复到目标状态。为唤起对CPS恢复的关注并梳理已有工作，我们共调研了30篇相关论文。我们识别出所提出恢复策略的一个主要划分：浅层恢复与深度恢复，前者不使用专用恢复控制器，而后者使用。此外，我们还调研了有助于恢复的主题上的探索性研究。基于这些文献，我们从应用、攻击类型、攻击面和系统动力学方面讨论了CPS恢复的当前最先进水平。随后，我们指出该领域尚未触及的子领域，并为研究人员提出可能的未来方向。
英文摘要：
Cyber-physical systems (CPS) have experienced rapid growth in recent decades. However, like any other computer-based systems, malicious attacks evolve mutually, driving CPS to undesirable physical states and potentially causing catastrophes. Although the current state-of-the-art is well aware of this issue, the majority of researchers have not focused on CPS recovery, the procedure we defined as restoring a CPS's physical state back to a target condition under adversarial attacks. To call for attention on CPS recovery and identify existing efforts, we have surveyed a total of 30 relevant papers. We identify a major partition of the proposed recovery strategies: shallow recovery vs. deep recovery, where the former does not use a dedicated recovery controller while the latter does. Additionally, we surveyed exploratory research on topics that facilitate recovery. From these publications, we discuss the current state-of-the-art of CPS recovery, with respect to applications, attack type, attack surfaces and system dynamics. Then, we identify untouched sub-domains in this field and suggest possible future directions for researchers.
