A tachograph and a toll onboard unit as communication partners, which each have a data interface for a data communication via a vehicle data bus to which the communication partners are coupled. The tachograph and/or the toll onboard unit are implemented as a transmitter of data to ascertain a cryptographic check value as a function of user data, which are to be transmitted to the communication partner, and to transmit the cryptographic check value in addition to the user data to the communication partner. The toll onboard unit or the tachograph, respectively, as a receiver of data, is implemented to receive user data and the cryptographic check value associated with the user data from the communication partner and to check the received user data for corruption as a function of the received cryptographic check value.

Tachograph, toll onboard unit, display instrument, and system

A docking terminal for controlling a plurality of vehicle functions of a motor vehicle by a control device connected to the vehicle, including a wireless data exchange with a control device, an input unit, and an energy store. A greater range of functions, which can also include control of safety-relevant vehicle functions, is facilitated by the connection of the wireless data exchange to a data processing system integrated in the docking terminal. The system is designed to use at least one cryptologic method.

Docking terminal and system for controlling vehicle functions

A mobile interface for controlling a plurality of vehicle functions in a motor vehicle using a controller connected to the vehicle, having a wireless data interchange with a controller, an input apparatus, and an energy store. By virtue of the wireless data interchange being connected to a data processing unit integrated in the mobile interface and which is designed to apply at least one cryptological method, a greater scope of functions becomes possible that can also include control of safety-relevant vehicle functions.

Mobile interface and system for controlling vehicle functions

An integrated circuit () is provided with function modules () which comprise a central processing unit () for treating data and executing a program and a cache memory (). Until now, it was complicated and costly to ensure the manipulation security of the modules. The function modules () comprise an encoding unit () for data encoding and decoding.

Arrangement comprising an integrated circuit

An energy storage unit, particularly for a motor vehicle, has an application unit that is configured to detect and/or process predetermined operating parameters of the energy storage unit. The energy storage unit further includes a safety unit that is configured to cryptologically process the detected and/or processed operating parameters. The energy storage unit also includes a communication interface for making the cryptologically processed operating parameters available.

Energy storage unit provided with application unit and a safety unit

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.
