Introducing the Vehicle Electrical/Electronic Architecture

The vehicle Electrical/Electronic (E/E) architecture refers to the set of electronic components, electrical wire harnesses, networking technologies, and software applications that coalesce to manage a diverse suite of vehicle functions tasked with controlling the vehicle and user experience.

While the combination of software and electronics has revolutionized how vehicle features are designed and deployed, it gradually produced a rich attack surface that made vehicles vulnerable to cyber threats. Therefore, understanding the fundamental concepts of the E/E architecture is a prerequisite to analyzing vehicle security. To help provide the necessary background, first, we will explore ...
