摘要: A communication device for a vehicle has a communication unit set up to establish a communication link between the vehicle and an external vehicle server and to exchange data in a cryptographically secured manner between the vehicle and the external vehicle server. The communication unit is further set up to be operated in a first or second mode. The modes differ in the type of cryptographic securing of the data. The communication unit has a secure hardware memory in which a binary value corresponding to the respective mode is stored.
