a processing apparatus for processing vehicle-to-X messages to be sent and received, wherein the vehicle-to-X communication device is configured to:
receive, by the receiving device, a vehicle-to-X message including information identifying a manufacturer of a further vehicle,
determine, by the processing apparatus, a level of trust of the vehicle-to-X message received from the further vehicle based on whether the manufacturer of the further vehicle is determined to be the same as a manufacturer of the vehicle, and
control, by the processing apparatus, the vehicle based on the determined level of trust.
2. The vehicle-to-X communication device according to claim 1 , configured to send out a vehicle-to-X message for identifying a manufacturer of the vehicle, which forms a standalone message type and contains information for identifying the manufacturer of the vehicle.
3. The vehicle-to-X communication device according to claim 2 , wherein the vehicle-to-X message for identifying the manufacturer of the vehicle contains identification information for identifying the vehicle in the vehicle-to-X network.
4. The vehicle-to-X communication device according to claim 3 , wherein the information for identifying the manufacturer of the vehicle is made up of a user data part contained by the vehicle-to-X message and/or a header data portion and/or a digital signature.
5. The vehicle-to-X communication device according to claim 2 , wherein the information for identifying the manufacturer of the vehicle is made up of a user data part contained by the vehicle-to-X message and/or a header data portion and/or a digital signature.
6. The vehicle-to-X communication device according to claim 2 , configured to encrypt the vehicle-to-X message by a manufacturer-related key prior to the vehicle-to-X message being sent out.
7. The vehicle-to-X communication device according to claim 2 , wherein the vehicle-to-X message furthermore contains:
information regarding technical equipment of the vehicle sending the message,
information regarding an age of the vehicle sending the message,
information regarding implementation details of hardware modules and/or software modules used in the vehicle sending the message,
information regarding a manufacturer of hardware modules and/or software modules used in the vehicle sending the message, and/or
information regarding a certification level of the vehicle sending the message.
8. The vehicle-to-X communication device according to claim 1 , configured to process information for identifying a manufacturer of the further vehicle received from the further vehicle.
9. The vehicle-to-X communication device according to claim 8 , configured to utilize the information for identifying the manufacturer of the further vehicle for assigning a vehicle-to-X message already received and/or to be received to the manufacturer.
10. The vehicle-to-X communication device according to claim 9 , configured to carry out the assignment, on the basis of the identification information for identifying the further vehicle already received and/or to be received, in the vehicle-to-X network.
11. The vehicle-to-X communication device according to claim 8 , configured to determine a level of trust of a vehicle-to-X message received and/or to be received from the further vehicle based on the information for identifying the manufacturer of the further vehicle.
12. The vehicle-to-X communication device according to claim 11 , configured to influence execution of a vehicle function depending on the determined level of trust.
13. The vehicle-to-X communication device according to claim 1 , configured to process at least one vehicle-to-X message received from the further vehicle, utilizing information for identifying a manufacturer of the further vehicle contained by said vehicle-to-X message.
14. The vehicle-to-X communication device according to claim 13 , configured to utilize the information for identifying the manufacturer of the further vehicle for assigning a vehicle-to-X message already received and/or to be received to the manufacturer.
15. A method for realizing functional safety for a vehicle-to-X network, comprising:
receiving, by a receiving device of a vehicle-to-X communication device of a vehicle, a vehicle-to-X message including information identifying a manufacturer of a further vehicle;
determining, by a processing apparatus of the vehicle-to-X communication device of the vehicle, a level of trust of the vehicle-to-X message received from the further vehicle based on whether the manufacturer of the further vehicle is determined to be the same as a manufacturer of the vehicle; and
controlling, by the processing apparatus, the vehicle based on the determined level of trust.
