Description
Technical field
The present invention relates to the authentication techniques in duplex computer switching.
Background technology
At present the existing information system of large enterprise is divided into physics between independent Intranet and outer net, and Intranet and outer net
Isolation, requires, staff needs individually to be equipped with two computers, connects respectively in order to meet Intranet and outer net working environment simultaneously
Intranet and outer net are connected to, and need that keyboard and mouse and display is separately configured to two computers, calculated by per platform respectively
The keyboard and mouse and display of machine is operated to computer.According further to different operating demand, in addition it is also necessary to be separately configured USB flash disk,
The computer peripheral equipments such as USB printer, USB scanners, USB handwriting pads, due to physical isolation characteristic between Intranet and outer net, calculate
Machine peripheral hardware cannot use network share, and frequently transfer plug is substantial amounts of between Intranet and outer net computer for staff's needs
USB peripheral, and the cable winds for thus bringing, bring the inconvenience in terms of the waste and work of great manpower.Therefore, need badly
A kind of device for adopting a display to switch between intranet and extranet main frame, then user is using the device in two calculating
When switching between machine, the device needs to examine the identity of user, in order to avoid information security is threatened.
The content of the invention
The invention aims to meet the development need of intranet and extranet computer switching device, there is provided two kinds based on double
The authentication module of calculation machine switch and two kinds of method for authenticating.
The first authentication module for being used for duplex computer switch is embedded in ARM, and the ARM is connected with intranet and extranet switching
Button and NFC reader：
The authentication module is included with lower unit：
Switching judging unit：Judge whether to receive the trigger that intranet and extranet switching key sends, and be in judged result
Start card reading unit when being, switching judging unit is restarted when judged result is no；
Card reading unit：Read the nfc card information that NFC reader is sent；
Authority open cell：The access right of user is judged according to nfc card information, and according to the access right to user
The corresponding authority of opening, then restarts switching judging unit.
The first method for authenticating for being used for duplex computer switch realizes that the ARM is connected with intranet and extranet switching based on ARM
Button and NFC reader：
The method for authenticating is comprised the following steps：
Switching judging step：Judge whether to receive the trigger that intranet and extranet switching key sends, and be in judged result
Card Reader step is performed when being, when judged result is no switching judging step is re-executed；
Card Reader step：The nfc card information that NFC reader is sent is read, and authority is performed after the step terminates and opened
Step；
Authority opens step：The access right of user is judged according to nfc card information, and according to the access right to user
The corresponding authority of opening, is then back to perform switching judging step.
The authentication module for being used for duplex computer switch second is embedded in ARM, and the ARM is connected with intranet and extranet switching
Button and fingerprint identification device：
The authentication module is included with lower unit：
Switching judging unit：Judge whether to receive the trigger that intranet and extranet switching key sends, and be in judged result
Start fingerprint identification unit when being, switching judging unit is restarted when judged result is no；
Fingerprint identification unit：Read the finger print information that fingerprint identification device is sent；
Authority open cell：The access right of user is judged according to finger print information, and according to the access right to user
The corresponding authority of opening, then restarts switching judging unit.
The method for authenticating for being used for duplex computer switch for second realizes that the ARM is connected with intranet and extranet switching based on ARM
Button and fingerprint identification device：
The method for authenticating is comprised the following steps：
Switching judging step：Judge whether to receive the trigger that intranet and extranet switching key sends, and be in judged result
Fingerprinting step is performed when being, when judged result is no switching judging step is re-executed；
Fingerprinting step：Read the finger print information that fingerprint identification device is sent, and the right of execution after the step terminates
The open step of limit；
Authority opens step：The access right of user is judged according to finger print information, and according to the access right to user
The corresponding authority of opening, is then back to perform switching judging step.
Two kinds of authentication modules and two kinds of method for authenticating for duplex computer switch that the present invention is provided, can be to difference
User open different access rights, it is ensured that information security, it is adaptable to the switching of power system intranet and extranet computer.
