An Overview of Automotive Cybersecurity: Challenges and Solution Approaches

In recent years, several academic teams demonstrated that it is possible to hack vehicles via every available interface (telematics, cellular, Bluetooth, etc.). In this presentation a brief overview of recent results will be presented, and current cybersecurity and privacy threats will be described including attacks on functional safety, attacks for financial purposes, attacks on infrastructure, and considerations around privacy. The differences of automotive cybersecurity to Internet data security will be analyzed, and we will explore why traditional security solutions and even Internet-of-Things security solutions often do not translate well to the automotive world. We will then consider future applications such as vehicle-to-vehicle communication and automated vehicles, and analyze what security risks and challenges these technologies introduce. Research results for implementing automotive cybersecurity will be presented, including connected vehicle security and privacy, secure in-vehicle communication, automotive firewalls and intrusion detection systems, trusted hardware, and formally verified communication interfaces. Finally, an overview of current research initiatives will be provided, and an outlook to future security and research demands will be given.
