LiBrA-CAN: Lightweight Broadcast Authentication for Controller Area Networks KU Leuven
© 2017 ACM. Despite realistic concerns, security is still absent from vehicular buses such as the widely used Controller Area Network (CAN). We design an efficient protocol based on efficient symmetric primitives, taking advantage of two innovative procedures: splitting keys between nodes and mixing authentication tags. This results in a higher security level when compromised nodes are in the minority, a realistic assumption for automotive ...
