A one-way coupling device for the feedback-free transmission of data from the first network with high security requirements into a second network with low security requirements, containing a request unit, an eavesdropping unit and a receiving unit, wherein the request unit is formed so as to provide a first communication link within the first network to at least one device and, moreover, to request first data from the at least one device and then to transmit the first data via a second communication link on a separate line loop of the request unit, and the eavesdropping unit, which is formed so as to eavesdrop on data on the separate line loop and to transmit data to a receiving unit which is arranged in the second network. Also, a corresponding request unit, a corresponding method and a corresponding computer program product is also provided.

One-way coupling device, request apparatus and method for feedback-free transmission of data

Provided is a method for decoupled transmission of data between networks having different security requirements, in which, in a first network having high security requirements, first data from a first application are transmitted in a communication exclusively between components within the first network via multiple communication links, data being captured in the first network by at least one monitoring device per communication link in a decoupled manner and being transmitted to a second network having lower security requirements. Also, a corresponding arrangement is also provided.
