Through the USB key device, malicious programs, such as computer viruses, Trojans and the like, can be effectively prevented from monitoring, recording and stealing PIN codes input by users, and the security during identity identifying is greatly improved by using the USB key.
Description
Technical field
The present invention relates to computer realm, more specifically, the present invention relates to a kind of usb key device.
Background technology
At present, usb key (just usually said USB Key) more and more widely be applied to the occasion that Web bank, ecommerce etc. need be carried out authentication.In order to improve security, the mode that usb key generally all adopts physical equipment and PIN code to combine is protected private key for user.
Traditional way is that the user must import PIN code by the soft keyboard on computer keyboard or the screen after usb key is inserted computing machine USB socket, could use usb key to carry out authentication.But because keyboard input information and displaying information on screen can be monitored and write down to Malwares such as computer virus, wooden horse, thereby steal user's PIN code, therefore there is hiding security risk in actual use in traditional usb key product.
Thus, people earnestly look forward to releasing a kind of usb key and remedy traditional usb key product safety defect in use, allow the user by keyboard on the usb key rather than computer system input PIN code, thereby prevent rogue programs such as virus, wooden horse monitoring, write down and steal, improve the security of authentication process.
Summary of the invention
Consider the problems referred to above and make the present invention, for this reason, fundamental purpose of the present invention is to provide a kind of usb key device, it makes the user by keyboard on the usb key rather than computer system input PIN code, thereby prevent rogue programs such as virus, wooden horse monitoring, write down and steal, improve the security of authentication process.
To achieve these goals, according to embodiments of the invention, provide a kind of usb key device, it comprises: the USB joint; Housing is used for clamping usb key joint and the usb key joint is stretched out from an end of housing; And internal circuit, be arranged in the housing and and be electrically connected with the usb key joint; Input block is electrically connected with internal circuit.
In this usb key device, input block and internal circuit are integrated, and are arranged on the outside surface of housing.
Alternatively, in this usb key device, input block is directly connected to internal circuit by cable.
Alternatively, in this usb key device, housing is provided with circuit interface, and circuit interface is electrically connected with input block and internal circuit respectively by cable.
In addition, in this usb key device, input block sticks on the outside surface of housing.
Alternatively, in this usb key device, input block is sleeved on the outside surface of housing.
Alternatively, in this usb key device, input block is arranged on the outside of housing.
In addition, in this usb key device, input block is a keyboard.
By the usb key device of the invention described above, can effectively avoid rogue program monitoring such as computer virus, wooden horse, write down and steal the PIN code that the user imports, improve greatly and use usb key to carry out the authentication process safe.
