Abstract

System and techniques for cyber-physical system defense are described herein. Sensor disagreements between a plurality of sensors over time can be sampled. Cluster analysis on the sampled sensor disagreements can be performed. A deviation indication can be provided in response to the cluster analysis resulting in disagreement density beyond a threshold.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A system for cyber-physical system defense, the system comprising:
 a sensor interface to receive sensor data from a plurality of sensors;   a sampling circuit set to sample sensor disagreements between the plurality of sensors over time;   a cluster circuit set to perform cluster analysis on the sampled sensor disagreements; and   an alert circuit set to provide a deviation indication in response to the cluster analysis resulting in disagreement density beyond a threshold.
