Hardware Security Primitives for Vehicles

In the last few decades, advances in vehicular technology have necessitated large increases in the number of Electronic Control Units (ECUs) within vehicles. These ECUs are required to communicate with other ECUs in order to achieve full functionality. The communication networks that connect the ECUs have been shown to pose significant security risks, as they can be the target for attacks. Establishing security in vehicles against attacks is a complex topic that has generated much interest as a focus of research. In this article, we will highlight current security approaches in terms of hardware modules and physically unclonable functions (PUFs).
