Hybrid communication for vehicles is a sensible and useful development for connected driving. It paves the way for integrating more systems, road users, and services into V2X data exchange. At the same time, IT security is and will remain a necessary and fundamental condition for V2X. Establishing an intelligent concept means consistent, homogeneous, and efficient IT security across the various V2X communications channels and standards. To ensure data protection for the entities communicating via the V2X network, each V2X message receives a signature before it is encrypted. This way, even within a hybrid communication network, security for V2X data exchange fulfills all requirements: data integrity, sender authenticity, sender authorization, replay detection, confidentiality, privacy protection, reliability, and revocation of trust.
