Abstract: An industrial control system providing security against tampering or modification generates periodic state thumbprints defining a state of control elements that may be forwarded to a security or safety appliance for comparison to a benchmark thumbprint indicating no tampering. The transmitted state thumbprint may capture not only programs but also configuration and environmental states of the control element.

Abstract translation: 提供防止篡改或修改的安全性的工业控制系统产生定期状态指纹，其定义可以转发到安全或安全设备的控制元件的状态，以便与不指示篡改的基准指纹比较。 传输状态指纹可能不仅捕获程序，还可捕获控制元件的配置和环境状态。
