Method for configuring a computer program

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; and the 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.

Microprocessor system and method for detecting the exchange of modules of the system

A method for monitoring the execution of a program executable on at least one microprocessor of a micro controller using a debug logic of the micro controller, with an exception, particularly an interrupt of the program execution, being triggered by the debug logic upon access to a specific address range during the program execution time. In order to provide monitoring of the execution of a program, executable on a microprocessor, for faults, which is particularly reliable yet conserves resources as much as possible, it is suggested that the debug logic be configured by the microprocessor and that an exception routine be executed by the debug logic after an exception has been triggered during the program execution time. The debug logic is advantageously configured during the startup of the micro controller. Preferably, the micro controller is reset and started up again and the monitored program is initialized during the execution of the exception routine.

Method for monitoring a program execution using a debug logic

A method of protecting a microcomputer system against manipulation of data stored in a memory arrangement of the microcomputer system, in particular a control program stored there. Checking mechanisms are executed at preselectable points in times to check for manipulation of the data. To permit effective blocking of manipulated data stored in the memory arrangement, new data is stored at least partially in a volatile memory, in particular in a random access memory, in reprogramming or new programming of the memory arrangement, the checking mechanisms are executed and the portion of the new data stored in the volatile memory is copied to the memory arrangement if no manipulation of the new data has been detected.

Method of protecting a microcomputer system against manipulation of data stored in a memory arrangement

A method of protecting a microcomputer system against manipulation of data stored in a storage assembly of the microcomputer system, in particular a control program stored there. Checking mechanisms are executed at preselectable points in times to check for manipulation of the data. To achieve the most complete test coverage within an acceptable period of time in checking data stored in a storage assembly of a microcomputer system, the storage assembly is subdivided into multiple logic blocks, at least one of the blocks is selected and the checking mechanisms are executed only for the or each selected block of the storage assembly.
