ASPIRE: Design of Secure Cyber Physical Systems

I. Goal

Conduct fundamental scientific research to improve the security of Cyber Physical Systems (CPS) that offer key services such as water and power.


Our focus is on the field of emerging unified industrial networks for CPS. Fully connected networks promise to enable applications such as robust distributed controls. Unfortunately, the inevitable trend towards an industrial internet-of-things also introduces novel threats to security and reliability. To understand these novel threats, expert knowledge in the area of communication systems, systems control, and the specific physical processes is required.



II. Technologies

1. Attacker Models

  • New CPS-centric models developed
  • Existing attacker models adapted to CPS


2. Process-based Models

Validation of EpanetWADI (the process-based model developed)


3. CPS Response to Attacks

Extensive experimentation on SWaT


4. Attack Detection Approaches

  • Physics-based
  • Hardware-based Attestation
  • Integrated (Fig 4a)
  • Orthogonal Defence (ARGUS) (Fig 4b)
  • Time to Being Unsafe
  • (Hybrid) Simulation
  • Mini-CPS Simulation Testbed
  • Attack Launcher
