    Abstract: A method for operating a tachograph having an application controller and a safety controller. A memory is associated with the application controller and a further memory is associated with the safety controller. An encrypted program code having at least one associated signature is made available to the safety controller. The encrypted program code is decrypted by means of the security controller and verified by the at least one signature. It is detected whether the decrypted program code (EPC) is intended for the application controller and/or for the security controller. Depending on what is detected, the program in the memory and/or the further program in the further memory is at least partially replaced by the decrypted program code and, depending on a result of the verification, the at least partially replaced program and/or the at least partially replaced further program is released for executing.

    Abstract: The invention relates to a method for secure data transmission, particularly between a tachograph (51) in a commercial vehicle and memory cards (50), where a first subscriber (T1) has a memory (6, 22) with entries (31-35) comprising identifiers (4) and security certificates (Cert) from second subscribers (T2). Methods for secure data transmission are becoming increasingly important and are frequently associated with a high level of computation complexity. For this reason, the object of the invention is to reduce the computation time for this without security losses. It is proposed that the first subscriber (T1) fetch an identifier (4) from the second subscriber (T2) and compare it with stored identifiers (4). If the identifier (4) matches, a security certificate (Cert) associated with this identifier (4) is the basis for a subsequent data transmission, and if the identifier (4) does not match then security certificate verification is performed.

    Abstract: An assembly has a tachograph and a data memory, in particular a data memory of a data card. The tachograph has an interface designed to exchange data between the tachograph and the data memory, logic function modules and at least one memory. In a method for operating the tachograph, as a result of high security requirements, the data transfer between the data memory and the tachograph is extremely time-intensive. At the start of the data transfer a virtual reproduction of the data memory is created in the memory of the tachograph and the logic function modules first have read and write access to the virtual reproduction in the memory. Data is then regularly written to the data memory of the data card by a write access to the memory, thus eliminating the differences between the virtual reproduction and the data memory.

    Abstract: A method for operating a volatile memory supplied with a supply signal arranged either as a first supply signal of a first supply signal source or a second supply signal of a second supply signal source. If an available first supply signal is present it is used otherwise the second supply signal is used. The supply signal is supplied, based on a switch position of a switching element to the volatile memory. During a detected interrupted first supply signal, the switch position of the switching element is for a predetermined period of time such that the supply signal is supplied to the volatile memory. After expiry of the predetermined period of time, the switch position of the switching element is predetermined such that the volatile memory is decoupled electrically from the supply signal.

    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.
