Critical infrastructures such as power grids, water supply systems, and traffic networks involve networked control systems with distributed sensors and actuators. We refer to them as cyber-physical systems. One key requirement for such systems is security from malicious attacks, often in the form of cyber-attacks aimed at compromising supervisory control and data acquisition (SCADA) systems. The second key requirement is fault tolerance: the ability of the control system to continue functioning despite component failures. Component failures can occur as a consequence of malicious actions by an attacker, but can also occur as a result of hardware breakdown or unforeseen operating conditions.

电网、供水系统和交通网络等关键基础设施涉及带有分布式传感器和执行器的网络控制系统。我们将它们称为网络物理系统。此类系统的一项关键要求是防止恶意攻击，这些攻击通常以网络攻击的形式出现，旨在损害监控和数据采集 (SCADA) 系统。第二个关键要求是容错：即使组件出现故障，控制系统仍能继续运行。组件故障可能由于攻击者的恶意行为而发生，但也可能由于硬件故障或不可预见的操作条件而发生。
