Description

Safe stochastic and dynamic soft keyboard

Technical field

The utility model belongs to digital certificate and payment technology field, be specifically related to a kind of network authentication and the integrality of transaction overall process and device of authenticity of guaranteeing, particularly prevent the password of the network equipment (computing machine, PDA etc.) input and the device that the electronic transaction data are stolen or distort.

Background technology

At present, known USB Key is based on the digital certificate key memory carrier of PKI (public key cryptography infrastructure) system, it also is the encryption device of finishing digital certificate encryption/signature, but the security that it can only guarantee after data message is exported through digital certificate encryption/signature in the Key can not guarantee from the security of the network equipment (computing machine, PDA etc.) input data information.When the network equipment (computing machine, PDA etc.) initiated to land with Transaction Information, these information just might be intercepted and captured or be distorted by illegal software, but the user but has no idea to find and prevents.

Summary of the invention

The purpose of this utility model is to propose a kind ofly can prevent the password of the network equipment (calculating, PDA etc.) input and the device that the electronic transaction data are stolen or distort.

The device that the utility model proposes is a kind of safe stochastic and dynamic soft keyboard, its structure as shown in Figure 1, the circuit module structure is as shown in Figure 2.It is connected to form through circuit by 1, one LCDs 2 of an equipment interface and safety chip 3, and wherein, equipment interface 1 is data communication and power interface, adopts common USB interface, SD card or CF card or 1394 interfaces; LCDs 2 is the output device of safety chip 3, is used for showing the dynamic random soft keyboard; The arrangement random variation of key assignments on the soft keyboard; The operation that the dynamic random soft keyboard is made is sent the business operation request through after the encryption of safety chip 3 to the outside; The randomness and the security of LCDs output soft keyboard are guaranteed by safety chip 3; Key assignments is gathered to stochastic and dynamic soft keyboard initiation coordinate information by keyboard and the mouse of the network equipment, computing machine or PDA itself; The identification of key assignments is finished by safety chip

The utility model is to have increased display screen on the basis of existing USB Key.Display screen is directly controlled by the safety chip in the terminal.The each key assignments that shows of stochastic and dynamic soft keyboard is produced by random algorithm by safety chip.The network equipment (computing machine, PDA etc.) is initiated coordinate information by itself keyboard and mouse to the stochastic and dynamic soft keyboard, carries out the collection of key assignments by coordinate information, and the identification of key assignments is finished by safety chip.The input information collection finishes again through uploading authentication center after the safety chip encryption.

The beneficial effects of the utility model are: prevent that the password of the network equipment (computing machine, PDA etc.) input and electronic transaction data are stolen or distort, provide display device (liquid crystal display) to be used for showing the dynamic random soft keyboard, the user carries out the input of user cipher and Transaction Information by the network equipment (computing machine, PDA etc.) control stochastic and dynamic soft keyboard.

This keyboard not only can be guaranteed the confidentiality and the integrality of transmission channel between the network equipment, also can guarantee simultaneously the safety input of password and Transaction Information, prevents to land, Transaction Information intercepted and captured or distort by illegal software.

Embodiment

Safe stochastic and dynamic soft keyboard of the present utility model as depicted in figs. 1 and 2.

In Fig. 1, equipment interface (can be USB interface or SD card or CF card etc., adopt USB interface in the sample): finish data communication, power interface etc., display part: show the stochastic and dynamic keyboard.

In Fig. 2, the safety of data communication is guaranteed by safety chip; The display part is directly controlled by safety chip, and the stochastic and dynamic keyboard of realizing on the display screen is as input equipment.The product safety characteristic is guaranteed by encryption chip fully.

Among Fig. 3, safety chip partly adopts 32 safety governors of Z32U series of emerging integrated circuit (IC) design Ltd in ZTEIC Shenzhen, and this controller adopts the homemade high safety kernel Arca2sc of custom-made.

Among Fig. 4, popular in the market OLED screen is adopted in the display part.OLED is the active illuminating device, does not need backlight, and thickness is thinner than common backlight screen, and only just power consumption when showing, power consumption is lower.

Among Fig. 5, power supply chip adopts a DC-DC booster power chip (LM2703) and the semi-conductive LDO chip of Taiwan power Qi (RT9193-33) of a National (American National semiconductor).

Among Fig. 6, equipment interface adopts general data-interface; Can adopt USB interface, SD card, CF card etc., adopt USB interface in the sample design.

Method of operating of the present utility model is as follows:

1, safe stochastic and dynamic soft keyboard inserts:

When wanting stochastic and dynamic soft keyboard safe in utilization to carry out network trading, safe stochastic and dynamic soft keyboard is inserted.

2, set up communication:

Passage is set up in safe stochastic and dynamic soft keyboard and authentication center's communication, the operation log-in interface.(in setting up process, some general informations that authentication center can initialization safety stochastic and dynamic soft keyboard are such as clock).

3, the account lands:

The password that the account lands must be imported by safe stochastic and dynamic soft keyboard by terminal PC, and the user gathers key assignments by the keyboard and the mouse of the network equipment (computing machine, PDA etc.) itself to stochastic and dynamic soft keyboard initiation coordinate information.Account and password are uploaded authentication center after safety stochastic and dynamic soft keyboard is encrypted, authentication center authenticates.

4, conclude the business:

(1) transaction content

Incoming traffic content: in the enterprising industry affair of PC content choice;

Consumer objects: on PC, import consumer objects;

Amount of money input: the input consumption amount of money on PC;

These information are filled in and are finished, and after the client confirmed, data were dealt into authentication center, and authentication center passes back to safe stochastic and dynamic soft keyboard with Transaction Information after handling, and shows on the safe stochastic and dynamic soft keyboard.

For example:

Business tine: remittance, purchase * * commodity, online seeing a film

Consumer objects: open * *, number of the account * * * *; The online film consumption in * * website

The consumption amount of money: * * * unit

Annotate: these business may not be put in order screen and all be shown, and can realize by the mode of page turning

(2) produce consumption and confirm random code

The client approve on the safe stochastic and dynamic soft keyboard show Transaction Information after, the client presses acknowledgement key, enter " trade confirmation random code " and confirm flow process, if the client will Cancel Transaction, can cancel this transaction by " cancelling key " by safe stochastic and dynamic soft keyboard, to the affirmation of business with cancel and to initiate by the button on the safe stochastic and dynamic soft keyboard.

The affirmation random code of this Transaction Success of beaming back such as display centre on the safety stochastic and dynamic soft keyboard is: 123456097

The coordinate information input that you just initiate by PC keyboard or mouse on safety stochastic and dynamic soft keyboard: 123456097.Input finishes, and this sign indicating number is passed back to the center confirm just passable.

(3) consume successfully

After comparison transaction random code in center is correct, think this Transaction Success, middle mind-set stochastic and dynamic soft keyboard sends " consuming successfully " information.
