Continues CPS Operation Under Attacks: Degradable HW Design

In a groundbreaking study recently published in an IEEE journal, researchers from UMBC and USNA have developed a novel method to enhance the security of sensor-estimator systems—critical components in cyber-physical plants. Funded by the Office of Naval Research, this innovative research offers a proactive defense mechanism against cyberattacks, particularly those targeting computational resources.

The paper, titled "State Estimation Adaptable to Cyberattack Using a Hardware Programmable Bank of Kalman Filters" introduces a robust strategy to maintain functionality even when part of the system's hardware is compromised. By employing a bank of Kalman filters distributed across multiple field-programmable gate arrays (FPGAs), the system ensures continuous operation and resilience. This distributed approach allows for dynamic adaptation through partial reconfiguration of FPGAs, ensuring that sensor data processing can proceed uninterrupted despite hostile cyber environments.

This method was successfully demonstrated using a radar-based prototype system designed to monitor the kinematics of a maneuvering unmanned surface vehicle (USV), showcasing its practical application and effectiveness in real-world scenarios. This research not only advances the field of cyber-physical system security but also sets a new standard for the design and resilience of sensor-estimator systems facing cyber threats.
