Abstract: The invention relates to a simplified symmetrical, cryptographic method. The basis of this method is an authentication code. This authentication code is calculated in a secured area, referred to as a trust center, by concatenating the application program, referred to as the flashware, with a secret data string and calculating a hash value from the concatenated application program. This hash value is calculated here by means of the application program and by means of the secret data string. This hash value is the authentication code for the application program to be checked. The authentication code is checked in the microprocessor system or in the control unit in which the application program is to be used. For this purpose, a second, identical, secret data string is stored in the microprocessor system or the control unit. Firstly, the unencrypted application program and the authentication code are transmitted into the micro-processor system or into the control unit.

Abstract: In checking the data integrity of software for transmission errors and authenticity during a download process, the flashed data is checked repeatedly. Such checking is configured in an efficient way by performing the calculation methods for checking for transmission errors and for checking for authenticity while the flashware is located in a buffer with a fast access time, so that lengthy access processes to the flash memory are avoided. It is therefore necessary to access the flash memory only once in order to buffer the flashware in a buffer with a fast access time for all the necessary checks.
