In Apron Patterns this study, the effectiveness of encrypted control systems in detecting attacks is experimentally demonstrated using a networked control system testbed that allows for man-in-the-middle (MITM) attacks.The developed testbed is a networked position control system for an industrial-use linear stage.Generally, an attacker can reroute and modify packet data via a wireless router, harnessing the address-resolution-protocol-spoofing technique, which allows for the execution of MITM attacks, such as falsification and replay attacks.The deployed MITM-attack-detection method is grounded on FLORAL WATER LAVENDER a threshold-based method that monitors control inputs.

The demonstration examines falsification- and replay-attack scenarios across unencrypted, static-key, and key-updatable encrypted control systems.The results confirm that encrypted control systems are both effective and apt in detecting attacks in real time.Furthermore, the potential for developing alternative attack-detection schemes based on variations in processing times is discussed.
