摘要： 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.

摘要： A detection device comprises a data memory (REG) which is arranged in a housing (G). The detection device further comprises a control unit (KE) with a nonvolatile memory (MEM) in which at least one reference datum (RD) is stored. The control unit (KE) is designed to determine at least one test datum (PD) and to store this in the data memory (REG). The control unit (KE) is further designed to read and test the at least one test datum (PD) for the presence and/or absence of modification with respect to the reference datum (RD). The control unit (KE) is further designed to recognize an opening of the housing (G) when the at least one test datum (PD) which has been read is modified or is not present. The detection device further has a deletion unit (LE) which is designed to delete or modify the at least one test datum (PD) in the data memory (REG) upon the occurrence of an opening signal caused by the opening of the housing (G).

摘要： The invention relates to a method for controlling a display (4) of a tachograph (DTCO) which can be connected to data memories (7) that are associated with defined groups. The aim of the invention is to improve this method so as to allow for an ergonomic control of the complex functionality of a digital tachograph while requiring little space. For this purpose, individual groups are associated with defined functional groups or dialogs of the display (4) and the operational controls (3). The tachograph (DTCO) identifies the group the data memory (7) is associated with and then displays a selection of functional groups that can be selected by means of operational controls (3). The display (4) displays only functions and functional groups that are associated with the group of the data memory (7).

摘要： A single-chip computer comprises at least one first processor core (P1) and at least one second processor core (P2), which are constructed on a common chip (C). The at least one first and the at least one second processor cores (P1, P2) are interconnected via a processor interface (PIF). Data can be read via a separate or common memory interface (MIF) from a separate or common data memory (DM) respectively and/or stored in said data memory. The single-chip computer additionally comprises an encryption and decryption unit (KRYPT) which is assigned to the at least one processor core (P2) and which is constructed and functionally arranged between the at least one second processor core (P2) and the memory interface (MIF) in such a way that the data which can be exchanged between the at least one second processor core (P2) and the data memory (DM) can be encrypted and decrypted by the encryption and decryption unit (KRYPT).
