Embodiment Construction

[0025] in figure 1 An exemplary configuration of the device VOR is shown. The device receives the electrical signal ESIG by means of a first receiving unit EE1, for example from at least one operating unit BE. The operating unit BE is configured as a keyboard or a mouse, for example. Therefore, the first receiving unit EE1 can be configured, for example, in the form of a USB port (USB: Universal Serial Bus) or a PS / 2 port that can electrically receive the cable KA1 that matches it. The plug where the cable is connected with the operating unit. The signal of the operating unit, such as the x-y coordinates or the corresponding keystrokes of the mouse, can be received by the receiving unit EE1 as an electrical signal ESIG via the cable KA1.

[0026] A transmission unit SE is depicted on the right side of the device VOR, which is designed to transmit the electrical signal ESIG to the calculation unit RE. Therefore, the sending unit of the device has a USB socket (Buchse) or a PS / 2...

Abstract

The invention relates to access control in the form of an apparatus. The apparatus can be used to unlock a device, wherein the device has a computation unit and at least one operator control unit thatis electrically connectable to the computation unit. The apparatus has a first reception unit for receiving electrical signals from the at least one operator control unit, a transmission unit for transmitting the electrical signals to the computation unit, a second reception unit for receiving at least one access message transmitted by means of an electromagnetic signal, an authorisation unit forgenerating a switching signal if the result of the check on the access message is that unlocking of the device is permitted by means of the access message, and an unlocking unit for unlocking a transmission of electrical signals from the first reception unit to the transmission unit on the basis of the switching signal. The apparatus and the developments thereof can be used, inter alia, in security-critical installations, such as a computer centre, a substation of an energy supplier, in production installations or in a hospital.

Description

Technical field [0001] The invention relates to a device for unlocking equipment for providing access control. Background technique [0002] Through the increasing use of IT-based equipment (hereinafter referred to as IT systems), operators often face in their daily work that the operator is working on multiple IT systems, such as personal computers, during his working day. , Robot facilities, control equipment in automation facilities, conveyor belts and other work equipment operated by IT technology. In order to improve the security regarding unauthorized operations of these IT systems, it is now standardized to request passwords from users before the IT systems are actually used. The password can then be entered into the corresponding IT system via the keyboard. [0003] However, it has been shown that users who change IT systems more frequently often keep logging in on the corresponding IT systems with their passwords, thereby compromising the security originally introduced b...
