Description of original award (Fiscal Year 2017, $50,000)
Today's cars contain multiple small computers forming a distributed on board computer network. Most new cars include wireless entry points to those networks which make them vulnerable to cyber attacks. Cyber attacks compromising vital vehicle systems, such as steering and brakes, pose a significant safety threat. The introduction of autonomous vehicles only magnifies that threat. The applicant proposes research to identify the vulnerabilities of vehicle computer systems to cyber threats and to develop counter measures to those threats.

Today's autonomous cars, otherwise known as driverless vehicles or self-driving cars, enable the deployment of safety technologies, such as collision warning, automatic emergency braking, and Vehicle-to-Vehicle technologies.
In the near future, these systems in all vehicles will help to achieve zero fatalities, zero injuries, and zero accidents. However, behind the potential of these innovations, there is new challenge on autonomous cars that still need to address: cybersecurity.
Most of autonomous vehicles use wireless signals to exchange information between vehicles about their location, direction, and speed. This collected information can be used to provide safety technologies.
Simultaneously, common communications networks enable autonomous cars to receive and transmit a great deal of information between sensors, actuators, and the electronic control units, provide access for attackers. From this point of view, cybersecurity is considered as new threats to public safety. Thus, the units that governs safety should be protected from malicious attacks, unauthorized access, or dubious activities which could interfere with public safety.
Unfortunately, while previous research efforts have largely considered attack models and detection methodologies of cybersecurity risks, very limited research efforts are known with respect to defense and mitigation technologies and the practical security issues in autonomous vehicles today. A typical automotive electronic control system mainly relies on the followings: sensors; actuators; communication networks; control algorithm. To examine the potential safety concerns associated with electronic sensors and prevent relevant crimes, there are three specific goals in this research: (1) to identify a mathematical model for autonomous vehicles, attacks, and observers; to analyze vulnerabilities of cyberattack via communication networks; to design observers to detect and identify attacks; (2) to develop countermeasures and defense strategies to maintain safety-critical systems (steering, braking, throttle, and power) functional under attacks; (3) to conduct experiments using autonomous robots to demonstrate the reliability and feasibility of the overall proposed study in a practical manner.
In order to achieve these goals, an approach from modern control engineering will be considered to design a robust filter or estimator that generates residuals which are insensitive to noise and uncertainties. Furthermore, three strategies (hybrid mode, multiple sensor fusion, isolation) will be proposed to mitigate the potential harmful consequences due to cyberattacks. Finally, two different types of simulation (SILS, HILS) and field tests will be performed. The proposed technology will impact on the automotive industry; vehicular study in academia; policymakers; criminal justice practitioner.
