Definitions

• the invention relates to an arrangement with a tachograph which digitally stores driver-related data in an internal first memory, with a mobile external data storage device having a second memory, with an external first interface on the tachograph and an external second Interface to the external storage device, which corresponds to the first interface, so that data between the first interface and the second interface are transferable.
• the new generation of tachographs does not store data, as before by recording on a paper chart, but in digital form electronically in a memory.
• the so-called digital tachograph which will soon be introduced to the market, uses an internal memory and a chip card, ie an external storage medium, to store the data.
• the chip card is completely picked up by the digital tachograph and completely isolated from the environment during data transmission between the internal memory of the tachograph and the memory of the chip card by means of mechanical precautions. To this Way, manipulation should be prevented.
• the advantage of using a smart card is that it is completely isolable from the environment.
• a disadvantage, however, is the high expense associated with isolation during data transmission.
• the data card has to be completely recorded by the digital tachographs, which accordingly has to identify a device for automatic recording and output.
• the opening through which the data card enters the tachograph must be able to be closed in a tamper-proof manner and, according to relevant regulations, it is necessary for this closure to be locked in the closed position.
• the high degree of mechanical safety precautions against manipulation is associated with high costs and a high outlay.
• the invention has set itself the task of making an arrangement and a method of the type mentioned less aufwen ⁇ dig and cheaper without sacrificing the Mani ⁇ pulation security.
• the tachograph has a first encryption unit which is assigned to the first external interface and the storage device has a second encryption unit which is assigned to the second external interface such that data is transferred between the first interface and the second interface are encrypted transferable.
• the invention proposes a method of the type mentioned in the introduction, in which the tachograph has a first encryption unit which is assigned to the first external interface and the memory device has a second encryption unit, which of the second external interface is assigned and data provided by be encrypted to the tachograph on the storage device, encrypted prior to transmission by means of the first encryption unit and data that are transmitted from the storage device to the tachograph before the transmission encrypted by means of the second encryption unit was ⁇ the.
• Both the arrangement according to the invention and the method according to the invention have the serious advantage over the known digital tachograph that a mechanical safeguard against manipulation, in particular protection of electrical contacts of the first interface and the second interface, is obsolete. Due to the omission of the very expensive chip card mechanism for feeding and Ausga ⁇ be the data card, the cost drops significantly, and the space requirement of the device decreases significantly. The keys required for a conventional digital tachograph for ejecting the chip cards are no longer required, which advantageously results in additional space on the front panel for additional operating elements. In addition, the sensitive mechanism no longer limits the life of the overall device. The security against manipulation is ensured according to the invention exclusively by means of the encryption before the data transmission. Any tearing of electrical signals in manipulative intent therefore does not lead to the desired result.
• the second memory of the external storage device may expediently be between 32 MB and 2 GB.
• unneeded Speicher ⁇ space can be suitably used for other applications.
• the encryption can advantageously be carried out by means of triple-DES (Data Encryption Standard) and RSA (asymmetric encryption method) algorithms.

• Such a plug connection is particularly expediently designed as a USB connection (Universal Serial Bus), wherein, in particular, the first interface on the tachograph can be designed as a socket and the second interface on the storage device as a plug.
• the design as a USB interface results in an advantageously high transmission rate, and at the same time this arrangement is particularly robust mechanically, in particular if the socket is arranged as preferred on the tachograph and the plug is arranged on the external memory device.
• the two interfaces involved can expediently be designed as wireless USB or Bluetooth chip arrangements.
• a wireless USB connection dung can already ⁇ transmission take place in a distance of 50 m. Besides is such training also compared to Bluetooth particularly low priced. Conveniently, a wireless USB connection can be made according to the WUSB standard.
• the data storage device can advantageously be supplied with the required operating energy by means of an integrated transponder.
• the external storage device can again have an exchangeable storage medium so that, in particular, driver-related data can also be moved independently of the external storage device.
• the external storage device can essentially have the function of an adapter or serve terminals for the transmission of data from the memory of a tachograph to a removable storage medium, the external storage medium essentially assuming the function of encryption.
• a further advantage of this arrangement lies in the fact that the storage device only has to be present for each tachograph in operation and no longer requires each user a separate copy.
• the storage device So that the user can conveniently check the correct functioning of the storage device, it is expedient if it has at least one light source, which lights up or flashes depending on whether a data transmission takes place.
• a second light source could also serve as an indicator of a correct power supply.
• this connection is designed such that the storage device of the Tacho ⁇ graphene is supplied with an operating power. To this The correct function is no longer dependent on the state of charge of a battery in the storage device.
