Communication in a Cooperative Intelligent Transportation System needs to be protected against attacks in order to ensure trust in received data in terms of data integrity and sender authenticity. In addition, the reliability of communication channels should be considered, which is not possible with a single technology or physical channel that cannot be easily protected against radio jamming attacks. Hybrid vehicular communications using different radio technologies and channels is mainly introduced to further increase channel bandwidth and the communication range with the goal to speed up the deployment of intelligent transportation systems. However, hybrid communication could also support the reliability of communication capabilities by using the potential of redundant communication technologies. In this paper, a security concept is described to secure data in presence of multiple radio technologies using different physical channels to transmit V2X information. The security is considered for different radio-level communication technologies, i.e. direct ITS-G5 communication based on IEEE 802.11p (DSRC), device-to-device communication based on Cellular-V2X using different configurations and Mobile Edge Computing.
