1. A vehicle-to-X communication apparatus comprising:
a reception device including a receiver or a transceiver, the reception device designed to receive a vehicle-to-X message,
a first electronic computation device designed to calculate a hash value for a received vehicle-to-X message,
a second electronic computation device designed to generate a new vehicle-to-X message using data included in the received vehicle-to-X message and to calculate a hash value for the generated vehicle-to-X message, wherein
the first electronic computation device is designed in accordance with a higher safety integrity level than the second electronic computation device, and
a comparison device designed to make a comparison between the hash value for the received vehicle-to-X message and the hash value for the generated vehicle-to-X message, wherein
the vehicle-to-X communication apparatus is designed to further process the data from the received vehicle-to-X message depending on a result of the comparison.
