Abstract

The method involves transmitting data between two computers of a computer system by generating test data in a source using a test data algorithm with several inter-dependent calculation steps, transmitting the test- and the usage data to a destination, and examining the usage data using the transmitted test data which are derived from the usage data according to the same test data algorithm. A first part of the calculation steps (F1...Fm), both in the source and the destination, is performed outside the respective computer, while the remaining calculation steps (Fn) are performed in the corresponding computers. Test data (P**) produced in the computer (SRS) of the source (Z) are compared with the transmitted test data (P) in the computer.
