Abstract

The invention concerns a secure multi-computer system in which only one of the computers (R1) has an output channel (ABG) through which data from the computer system are transmitted to a receiving terminal. The data transmitted include wanted data (N1) and test data (P2) which can be identified in a predetermined way from the wanted data. The transmitted wanted and test data come from different computers in the computer system. For instance, the wanted data may come from the computer which feeds the data into the transmission channel and the test data (P2) from another computer (R2). Since the computers in the computer system inform each other continuously about the data in their databuses, the outputting computer is always informed of the wanted and test data from the other computer. Suitable wiring ensures that both computers participate in providing the data transmitted.
