Description
Technical field
The utility model relates to information security field, relates in particular to a kind of electric signing tools and password input system.
Background technology
Code keypad is one of requisite computer peripheral of financial POS, is widely used in service industries such as bank, industry and commerce, the tax, supermarket, is used with bank transaction system, POS machine and management system etc., is mainly used in the input password.Along with bank card user's in vogue day by day with bankcard consumption of increasing, code keypad obtains people's attention more and more.
In addition, the application of electric signing tools (being also referred to as Electronics Cryptographic Keys or electronic key equipment) also more and more widely, particularly in the financial field; For the security that guarantees to conclude the business; The user of Web bank uses electric signing tools more and more, for example, and through USB (Universal Serial Bus; USB) USB Key of linking to each other with transaction terminal (being generally personal computer) of interface etc. is as the instrument of authentication and transaction authentication.
At present, also exist a kind of on hardware, have multiple connected mode is discerned the USB device with adaptive ability, this USB device has following characteristics:
1) has the USB mechanical interface shape and the pin of standard, can link to each other with the USB interface of host side;
2) USB interface D+ and D-pin had USB standard and two types of use-patterns of non-USB standard; USB standard use-pattern meets the electric and protocol specification of usb protocol, and non-USB standard use-pattern does not meet the electric and protocol specification of usb protocol;
3) equipment can identify the use-pattern different with the D-pin to D+ at hardware view.
Application number is 201010142982.X, the one Chinese patent application that name is called " USB Key device and utilize USB interface to realize the method for smart card communications " put down in writing a kind of have multiple connected mode is discerned the USB device with adaptive ability.What the USB device that this patent is put down in writing was discerned its connection through the level on D+ or the D-pin is USB main equipment (standard use-pattern) or USB card reader (non-standard use-pattern).
