Leveraging Hardware Security to Secure Connected Vehicles

Corbett, Christopher / Schmidt, Karsten / Brunner, Martin / Schneider, Rolf / Dannebaum, Udo

Advanced safety features and new services in connected cars depend on the security of the underlying vehicle functions. Due to the interconnection with the outside world and as a result of being an embedded system a modern vehicle is exposed to both, malicious activities as faced by traditional IT world systems as well as physical attacks. This introduces the need for utilizing hardware-assisted security measures to prevent both kinds of attacks.In this paper we present a survey of the different classes of hardware security devices and depict their different functional range and application. We demonstrate the feasibility of our approach by conducting a case study on an exemplary implementation of a function-on-demand use case. In particular, our example outlines how to apply the different hardware security approaches in practice to address real-world security topics.We conclude with an assessment of today’s hardware security devices. Based on our presented case study we outline the identified gaps and derive the necessary future developments for next-generation hardware security devices to meet the requirements for automotive applications.
