Embodiment Construction

[0035] figure 1 A computing device 10 is shown, which has a computing device 11 . The computing device 11 is connected via a data gate 12 , an input data diode 13 and via an interface device 14 to a communication network 20 , which is only shown briefly. Through the communication network 20 , the computing device 10 can receive the data and the request message Sa from the external data sending device 30 . The communication network 20 can be, for example, an office network or the Internet.

[0036]The data gate 12 has a first connection 12 a connected to an input data diode 13 . The second connection 12 b of the data gate 12 is connected to the computing device 11 . The data gate 12 includes a buffer register 121, which can realize temporary storage of data. The buffer register 121 is connected via a first switch 122 to the second terminal 12 b and via a second switch 123 to the first terminal 12 a. Both switches 122 and 123 can be off at the same time, but never on at the...

Abstract

The invention relates to, inter alia, a computing system (10) with a computing device (11). According to the invention, the computing system (10) has an input data path (100), which unidirectionally connects an interface device (14) of the computing system (10) to the computing device (11), and an output data diode (15), which unidirectionally connects the computing device (11) to the interface device (14). The input data path (100) has a data lock (12) which is connected to the interface device (14) by means of a first terminal and to the computing device (11) by means of a second terminal, and the data lock (12) has a temporary storage unit (121) for temporarily storing data and is designed such that the temporary storage unit (121) can be selectively connected solely to the first or second terminal but not to both terminals simultaneously. The computing device (11) is designed to accept data present in the interface device (14) from the interface device (14) solely if the data is transmitted to the computing device (11) from the interface device (14) via the input data path (100) within a transmission session (SES) initiated by the computing device (11) using the output data diode (15).

Description

technical field [0001] The present invention relates to computing devices and methods for operating computing devices. Background technique [0002] There is an increasing need for remote maintenance (technical term "Remote-Access") of safety-critical computing equipment. In some applications, however, the plant elements to be maintained are located in special secure areas that cannot be directly accessed remotely. [0003] Additionally, there is an increasing need for networking of security-related devices with traditional IT systems. In the case of such networking, it must be ensured that only permissible information elements are transmitted over the connections via these data networks. For all other and not permitted information, the data networks must be separated from each other. [0004] Data network connections may be known as bi-directional, for example by means of routers or gateways with firewalls. Today, however, critical networks with very high protection req...
