Arrangement for ensuring secrecy in the transmission of information in a computer system

Abstract

Abstract The present invention relates to an arrangement for ensuring secrecy in the transmission of information in a computer system, in order to prevent disruptive programs spreading uncontrolledly. This is brought about by virtue of the fact that the arrangement, in protected use of the computer system, breaks the connection either between the computer and the mass storage 10 or between the computer and the floppy disk drive 20. Moreover, the content of the main memory 14 is erased when switching takes place between the two connection states. The connection between the mass storage 10 and the floppy disk drive 20 can be brought about by the arrangement by authorization being checked in a manner known per se and also by, for example, a switch 22 located on the arrangement being operated, which requires the physical presence of an authorized operator. <IMAGE>
