Abstract

The computer arrangement contains at least two secure computers or at least three channels that process identical input data and each computer is connected to an external remanent memory that stores the on/off state of a partner computer and security-critical events or their existence. Starting the partner computer is either inhibited or allowe4d with restrictions if it is off and there is at least one security-critical event.
