Devices, methods, and a computer program for releasing transportation vehicle components and a vehicle-to-vehicle communication module. The device for releasing a vehicle component of a transportation vehicle includes at least one interface for communication with further vehicle components of the transportation vehicle and a control module for controlling the at least one interface to receive messages from the further vehicle components of the transportation vehicle and to verify the identity of the further vehicle components based on the received messages and the stored identification data of the further vehicle components. The messages on which the verification of the identity of the further vehicle components is based are messages used in regular operation of the vehicle component. The control module also releases the vehicle component in response to the identity of the further transportation vehicle components being consistent with the stored identification data of the further vehicle components.
