Abstract

The increasing local and remote wireless connection possibilities available to common vehicles (such as cellular, Bluetooth, V2X communication) have raised significant cybersecurity concerns. This paper presents an up-to-date compilation about security vulnerabilities present in the most relevant in-vehicle communication buses (CAN, LIN, FlexRay), and a summary of various cybersecurity proposals for CAN and FlexRay, from various authors. Possible cyberattacks on the LIN bus are presented in detail, in order to outline the design of a robust IT security layer for this bus, thereby significantly contributing to the safety of vehicle occupants.
