In-Vehicle Networks and Security

Abstract

Vehicles are experiencing a rapid evolution: mechanical systems are rapidly extended, or even replaced, with electrical systems, leading to highly computerized vehicles. Wireless connectivity, such as telematics and vehicle to everything (V2X), is being introduced to help connect vehicles with the world around them. The information exchanged via these interfaces is used to improve, among others, safety, convenience, comfort, and efficiency.

However, adding connectivity is at the same time opening the Connected Car to a multitude of security problems. Modern vehicles are highly complex cyber-physical systems with a high degree of automation and loads of (valuable) data. As such, they are an attractive target for hackers. But until recently, it was not possible for hackers to attack vehicles remotely, at large scale. The wireless connections are changing the game—as they form new entry points for hackers into the vehicle networks and systems. Most vehicles that are currently on the road were not designed with security in mind. And consequently, there were a few big-impact vehicle hacks last year that made headlines in the mainstream media.

To properly prepare vehicles for their connected future, concepts such as security by design, privacy by design, defense in depth, and life-cycle management must be applied. In this chapter, we will present a structural approach to applying these principles to in-vehicle networks.
