Abstract

A system and method for transmitting data via a transmission path between a tachograph arranged in a vehicle, and a data processing device which is remote from the vehicle. To improve data protection, the transmission takes place via a first path section of the transmission path, which path section is arranged between the tachograph and a communication controller arranged in the vehicle, and a second wireless path section of the transmission path, which path section is arranged between the communication controller and the data processing device. The tachograph in response to an encryption request signal sent from the data processing device to the tachograph encrypts data sent from the tachograph to the data processing device. The data is transmitted in encrypted form from the tachograph to the data processing device both via the first path section and via the second path section.
