The automotive industry has started a major transformation process where everything from car keys to the hand-break have become digital. Modern vehicles have several wireless interfaces and are connected with various devices and the Internet. This connectivity adds great functionality but it also introduces a number of security and privacy threats. Moreover, safety critical functionality of the vehicle is controlled by a multitude of computing units which are fully programmable. As vehicles become more programmable and interconnected, they also become more vulnerable to cyber-attacks.

We will present LeiA, a lightweight authentication protocol for CAN . Its purpose is to secure critical functionality, such as communication, between the different computing units. We need to reconcile the tension between safety, availability and security. All this functionality should be implemented in the most stringent time and resource constrained environment where bandwidth and memory are limited and where a few microseconds can make a life-saving difference.
