摘要： A method is provided for controlling a microcontroller in a control unit in a motor vehicle, having a processor core, at least one read-only memory area and at least one rewritable memory area, at least one control program which is intended to be processed by the processor core being stored in the rewritable memory area. In order to provide a method for controlling a microcontroller in a control unit that better protects the verification of memories of the microcontroller against unauthorized intervention, a verification program is stored in a write-once memory area of the rewritable memory area and a service program is stored in the read-only memory area. The verification program is called by the control program via the service program at regular intervals and verifies at least part of the rewritable memory area. In addition, the service program resets a counter. A RESET of the control unit is triggered by the verification program when manipulation of the verified memory area is detected or by the counter in the event of counter overflow.

摘要： A microprocessor system includes a plurality of modules, among them a microprocessor and at least one storage module for storing the code and/or data for the microprocessor. Stored, in a non-changeable manner, in at least one of the modules, referred to as exchange-protected module, is a serial number of this module. A control module is configured to receive a data value specified by the at least one serial number and to block, at least partially, the function of the microprocessor system if the received data value does not match an expected data value encoded in the control module.

摘要： In order to detect the exchange of a module, identified by a serial number, in a microprocessor system,a code number, which is obtained from the serial number by using an encryption method, as well as information required for calculating the serial number from the code number, are stored in the microprocessor system;the code number is read and an unencrypted serial number is calculated from the code number with the aid of the information; andthe decrypted serial number thus obtained is compared to the serial number of the module and the module is detected as exchanged if its serial number does not match the decrypted serial number.

摘要： A method for protecting a microcomputer system against manipulation of data stored in a storage arrangement of the microcomputer system, in particular for protecting a program stored in the storage arrangement. The microcomputer system includes a microcomputer assigned to the storage arrangement, the microcomputer accessing the storage arrangement for the purpose of processing the data, i.e., the program. In order to prevent the manipulation of data in a microcomputer that does not have an internal memory but rather accesses an external storage arrangement and processes the stored data, it is proposed that before the storage arrangement is accessed, an individual identifier be assigned to the or to each allocated microcomputer or to the storage arrangement that a comparison code be generated as a function of the individual identifier and be stored in the storage arrangement, and that, before or during the operation of the microcomputer system, a security code be generated as a function of the individual identifier and be compared with the comparison code.

摘要： A method and a device for testing a computer core in a processor having at least two computer cores is described. The computer cores are connected to each other via an internal connecting system, both computer cores contributing toward the operating sequence of a machine. In the method for testing a computer core, with which a high error detection rate may be achieved in a minimum outlay of time, a test is run in one computer core, while a program for executing the driving operation of the motor vehicle is being processed in the other computer core at the same time.

摘要： A method and apparatus for monitoring an electronic control system such that provision is made for the complete data of at least one memory to be read sequentially into an ECC unit, which can be filled very rapidly from the memory, and automatically checked there, with no need to transfer the complete data in time-consuming fashion to a processor; the ECC check width encompassing the data of a plurality of memory cells of the memory and being able to be a multiple of the read word width of the processor; an additional datum being created in each case for the data of a ECC check width and being storable in the memory, and the entire code/data region of the at least one memory therefore being able to be checked, outside the ongoing instruction accesses, by the fact that for each request by the processor for the contents of a single memory cell, the ECC unit is filled from the memory to the entire ECC check width including the additional datum; a check datum being created from the data of the complete ECC check width and the check datum automatically being compared, in the ECC unit, with the stored additional datum.
