Device for physical security unidirectional switching control of keyboard and mouse

Abstract

The invention provides a device for physical security unidirectional switching control of a keyboard and a mouse. The device comprises a USB interface module connected with the keyboard and the mouse. The USB interface module is connected with a real-time monitoring module, the real-time monitoring module is connected with a unidirectional transmission module, the unidirectional transmission module is connected with a plurality of analog keyboard and mouse modules through a switching control module, each analog keyboard and mouse module is connected with a host, and the real-time monitoring module is connected with the switching control module. Moreover, a warning module is connected with the real-time monitoring module. According to the device according to the scheme, on the conditions of using the same keyboard and mouse, the different hosts and displays are switched to enter different network environments such as an intranet and an extranet, data of the keyboard and the mouse can only be transmitted to the hosts, and data are prevented from being stolen from the keyboard and the mouse.

Description

Technical field: [0001] The invention relates to the computer field, in particular to a physical safety one-way switching control device for using the same set of keyboard and mouse with different networks. Background technique: [0002] The keyboard and mouse are our most commonly used input devices, and they are also general-purpose devices that we generally believe to be very safe. The potential safety hazards have not been paid attention to. There is no technical difficulty in developing a keyboard and mouse with storage and attack functions. Its hazards are similar to those of U disks. The ferry is the same, and it is more concealed and difficult to detect, so the security risks brought by the keyboard and mouse cannot be ignored. [0003] At present, my country's government, military industry, and enterprises all use networks in different security domains in the office informatization, which are generally divided into extranets, intranets, and secret-related networks. ...
