Safety-Related Cooperative, Connected, and Automated Mobility Services: Interplay Between Functional and Security Requirements

Together with the electrification of vehicles, the provision of cooperative, connected, and automated mobility (CCAM) services is a prominent recent trend in the automotive sector. Upcoming car models will be able to exchange messages between themselves and with road traffic authorities by means of vehicle-to-everything (V2X) communication—in particular, leveraging mobile network technologies for the cellular V2X (C-V2X) paradigm

. Moreover, (part of) such exchanged messages will be processed as a whole in, e.g., edge computing servers, to generate a global vision of the state of a given stretch of road. CCAM services will exploit vehicular information transport and processing to implement complex maneuvers in a (semi)automatic manner by interacting with the in-car network.
