Abstract
The invention provides a technical scheme of a method for achieving unidirectional transmission of a keyboard and a mouse. According to the method in the technical scheme, an electrical signal is converted into a light signal, the data safety unidirectional performance of the keyboard and the data safety unidirectional performance of the mouse are achieved through the transmission unidirectional performance of light, and data are prevented from being stolen from the keyboard and the mouse; gap-free physical switching can be further achieved by rapidly sliding the mouse left and right, so that two hosts are controlled with one set of keyboard and mouse, and using and operating of a user are convenient.
Description
Technical field:
What the present invention relates to is the technical field of a kind of keyboard and mouse, especially a kind of method realizing keyboard and mouse one-way transmission.
Background technology:
Keyboard and mouse is our the most frequently used input equipment, also be that we generally believe very safe common apparatus, its potential safety hazard does not draw attention always, research and develop the keyboard and mouse with storing and attack function, in technology without any difficulty, its harm is the same with USB flash disk ferry-boat, and more hidden, the potential safety hazard that keyboard and mouse brings not easily detects, so can not be ignored.
All to use the network of different security domain in the Office Information of the current Chinese government, military project, enterprise, generally be divided into outer net, Intranet, classified network.Between the network of different security domain, need transmission of information, need the main frame of blocked operation different network domains.Under wishing the state that efficient, a safe technological means can be in Secure isolation between network per family, realize data transmission easily, operate the main frame of different network domains easily.A set of keyboard, mouse is used to carry out free blocked operation between the host table of two isolation networks.Therefore need the unidirectional mouse-keyboard handoff technique of high security high availability, namely facilitate user under the condition using a set of keyboard and mouse, different safety net territories host table is operated easily.
Summary of the invention:
Object of the present invention is exactly for the deficiency existing for prior art, and a kind of technical scheme realizing the method for keyboard and mouse one-way transmission is provided, the transmission method of the program, be light signal by transform electrical signals, the transfer of unidirectional of light is utilized to realize the data security one-way of keyboard and mouse, realization prevents data from stealing from keyboard and mouse, can also horizontally slipping fast by mouse, the physics realizing zero gap switches, make same set of keyboard and another main frame of mouse control, user-friendly and operation.
This programme is achieved by the following technical measures: a kind of method realizing keyboard and mouse one-way transmission, comprises the steps:
1) whether real-time monitoring module inspection access mouse and keyboard are QWERTY keyboard and mouse, if yes then enter step 2), otherwise report to the police;
2) real-time monitoring module receives the key signals of mouse or input through keyboard, and by light emission module, corresponding signal is converted to light signal and transmits;
3) light signal received is converted into key assignments by Optical Receivers, is then delivered to main frame by simulating keyboard and mouse module.
Described QWERTY keyboard and mouse are HID keyboard and mouse.
Keyboard is connected with real-time monitoring module by USB interface with mouse.
Described step 3) in simulating keyboard and mouse module be two, two keyboards and mouse module respectively from different main frame connecting communications, remain the enumerations information of keyboard and mouse.
Described simulating keyboard and mouse are by USB interface and main frame connecting communication.
Real-time monitoring module detects and is switched to another simulating keyboard and mouse the need of by the simulating keyboard of current use and mouse, if need to switch, then control signal relay switches, Optical Receivers is connected with another simulating keyboard and mouse, otherwise, maintain the annexation of former simulating keyboard and mouse.
Real-time monitoring module detects that the translational speed of mouse and scope detect, if the translational speed of mouse and scope reach the threshold value of setting, then switches.
Described step 1) in, adopt pilot lamp to report to the police.
The beneficial effect of this programme can be learnt according to describing of such scheme, be whether the HID keyboard of standard because real-time monitoring module in this scenario detects, so just tentatively can guarantee safety, prevent off-gauge HID class keyboard and mouse importing virus and wooden horse to destroy data message; Real-time monitoring module receives the key signals of mouse or input through keyboard, and by light emission module, corresponding signal is converted to light signal and transmits, and this ensure that the one-way transmission of data, ensure that the information security of main frame; Simulating keyboard and mouse module are two, two keyboards and mouse module respectively from different main frame connecting communications, so just can with the main frame in same set of mouse and keyboard operation heterogeneous networks, convenient operation person uses.As can be seen here, compared with prior art, have outstanding substantive distinguishing features and significant progress, its beneficial effect implemented also is apparent in the present invention.
Embodiment:
For the technical characterstic of this programme can be clearly demonstrated, below by embodiment, this programme is set forth.
