Description

The usb key device

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.

Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of instructions, is used from explanation the present invention with embodiments of the invention one, is not construed as limiting the invention.In the accompanying drawings:

Fig. 1 is the block diagram according to the usb key device of first embodiment of the invention;

Fig. 2 is the block diagram according to the usb key device of second embodiment of the invention; And

Fig. 3 is the block diagram according to the usb key device of third embodiment of the invention.

Embodiment

Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.

Fig. 1 is the block diagram according to the usb key device of first embodiment of the invention.

As shown in Figure 1,usb key device 100 comprises: USB joint 102; Housing 104 is used for clamping usb key joint 102 and usb key joint 102 is stretched out from an end of housing 104; And the internal circuit (not shown), be arranged in the housing 104 and and be electrically connected with usb key joint 102; Input block 106 is electrically connected with internal circuit.

In the first embodiment of the present invention, input block 106 is integrated and be arranged on the outside surface of housing with internal circuit.In addition, in the present embodiment, input block 106 is a keyboard.But it will be understood by those skilled in the art that and to utilize the input media of realizing identical function to replace keyboard.

Thereby, as shown in Figure 1, an integrated keyboard on the usb key housing, the circuit of keyboard directly is connected with the usb key internal circuit.

Fig. 2 is the block diagram according to the usb key device of second embodiment of the invention.

In usb key device shown in Figure 2, its most of parts are identical with the parts shown in Fig. 1.Owing to these parts are described,, only describe parts and the structure different here with Fig. 1 so just repeat no more.

As shown in Figure 2, different with usb key device shown in Figure 1, in theusb key device 200 of second embodiment of the invention, input block 206 is directly connected in theinternal circuit 208 by cable.That is, keyboard is connected with the usb key internal circuit by cable.In addition, in Fig. 2, keyboard can be made into sheet (even film like), sticks on the usb key housing 204.Alternatively, keyboard also can be made into the plastics shell-like, is sleeved on the usb key housing 204.Alternatively, input block 206 is arranged on the outside of housing 204.

Fig. 3 is the block diagram according to the usb key device of third embodiment of the invention.
