About the Project

As self-driving cars turn from a dream into a reality, and as our lives become increasingly dependent on software-controlled medical devices such as, for example, pacemakers and insulin pumps, guaranteeing the security of such Cyber-Physical Systems (CPS) and their robustness against hacker attacks becomes of paramount importance. Notable examples of such attacks include the disruption of a vehicle breaking system by injecting faulty sensor data, or compromising the function of an insulin delivery device.

The rigorous development of such life-critical systems using mathematical models and sound methods for their analysis can greatly improve manufacturers’ ability to build public trust in the systems’ resilience to cyber-crime. Due to this, the security-aware modelling and design of CPS has recently become an important research topic in computer science. Since such systems include complex interactions between physical and cyber components, they are susceptible to a much wider range of attacks than traditional software systems. This requires the development of appropriate formalisms for describing such attacks in a precise way, and methods for providing a certain degree of confidence in their security against such attacks.

The goal of this project is to address these challenges by developing methods for the testing of CPS against formally specified security requirements. By identifying security vulnerabilities through testing and eliminating them through system re-design, the resulting methodology for CPS development will be able to provide a level of confidence in the final product. By building upon and extending formalisms for the specification of security properties and established notions for conformance testing of CPS, this research will provide novel methods and tools for rigorous security-aware development of CPS.

The developed techniques will be evaluated on case-studies in the domains of autonomous vehicles and medical devices. The research outcomes will be of interest for national and international defence and security labs.
