Connected mobility is developing at a rapid pace. The focus here is on functional and traffic safety together with intelligent technologies. Both are only possible through V2X communication: the exchange of data between vehicles and with the traffic infrastructure.
V2X constantly provides networked vehicles with a large amount of information to guide them, automated or not, to make decisions that are appropriate for traffic. The cybersecurity of V2X communications is of key importance. This is because the effectiveness of the system depends on how accurate and trustworthy the information is. Traditionally, in IT security, the trustworthiness of information is ensured by identifying and authenticating its sender.
