Keyboard-mouse unidirectional transmission device

Abstract

The invention provides a keyboard-mouse unidirectional transmission device. According to the technical scheme, the keyboard-mouse unidirectional transmission device comprises a USB interface module respectively connected with a mouse and a keyboard, wherein the USB interface module is connected with a real-time monitoring module for monitoring the mouse and the keyboard of a user, the real-time monitoring module is connected with a mainframe communication module through an unidirectional transmission device, and the mainframe communication module is connected and communicated with a mainframe through an interface. In addition, the real-time monitoring module is further connected with a sound-light alarm module. Data of the mouse and the keyboard in the device are unidirectionally transmitted through a light transmitting-receiving tube to ensure that the data can be only transmitted to the mainframe. The data are prevented from being stolen or destroyed through the keyboard and the mouse, the HID-type keyboard and mouse used by the user are monitored in real time, and a nonstandard HID-type keyboard and a nonstandard HID-type mouse are isolated and alarmed.

Description

Technical field: [0001] The invention relates to a keyboard and mouse one-way transmission device for a computer. 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. Information needs to be transmitted between networks in different security domains, and host...
