A method for which is safe for signaling purposes transmit data between the computers which is safe for signaling purposes as well as apparatus for this purpose

摘要

A method for which is safe for signaling purposes transmission of data between two computers which is safe for signaling purposes of a computer system by a simultaneous generation of test data source on the basis of a test data algorithm with a plurality of calculation steps, are built on top of one another, transmission of the test - and the user data to a sink and a perpendicular to the surface of this check of the user data on the basis of the communicated and according to the same test data algorithm itself test data derived from the useful data, characterized by means of which both quelleals also a perpendicular to the surface of this embodiment of a first part of the calculation steps (f1.. fm) outside of the respective which is safe for signaling purposes computer (srq, srs),Embodiment of the or of the remaining calculation steps (fn) in the associated secure computeras well as comparison of the in the reliable computer (srs) of the sink (z) complete test data (p * *) with the transmitted test data (p) in the reliable computer.
