The realization of the object of the invention, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
Embodiment
With reference to Fig. 1; Dynamic token first embodiment that the present invention is provided with the light signal output unit is proposed; Comprise: memory cell 11, microprocessing unit 10 and light signal output unit 15, microprocessing unit 10 can be MCU, or has the circuit of the discrete element formation of MCU function; Preferably, this microprocessing unit 10 is the safety chip of built-in encryption engine.Microprocessing unit 10 is connected with light signal output unit 15 with memory cell 11 respectively, and said memory cell 11 is controlled with light signal output unit 15.Light signal output unit 15 is used for transmitting information to external equipment such as main frame with light signal.
Usually dynamic token also comprises display screen 14 and screen control module 13; Display screen 14, screen control module 13 are connected with microprocessing unit successively; Show the control signal of microprocessing unit 10 or the information of light signal output unit 15 transmissions etc., the user is checked.
With reference to Fig. 2; Light signal output unit 15 comprises led drive circuit 151, LED152 and current-limiting resistance R, and shown in Figure 2 is a circuit diagram of light signal output unit 15, and the positive pole of LED152 connects power supply VCC through current-limiting resistance R; The negative pole of LED152 connects led drive circuit 151; Led drive circuit 151 is connected with microprocessing unit 10, receives the control signal of microprocessing unit 10, and outwards sends light signal according to this control signal driving LED 152.
Shown in Figure 3 is another circuit diagram of light signal output unit 15; The positive pole of LED152 connects led drive circuit 151; The negative pole of LED152 is through current-limiting resistance R ground connection; Led drive circuit 151 is connected with microprocessing unit 10, receives the control signal of microprocessing unit 10, and outwards sends light signal according to this control signal driving LED 152.
The dynamic token of present embodiment is outwards exported light signal through LED; Export the key data etc. that generates the required cryptographic key factor of dynamic password or be used to generate cryptographic key factor to external equipment; Adopt this mode to accomplish the programming of cryptographic key factor; The opening that is designed on the dynamic token shell through contact communication programming cryptographic key factor can be not be used in, the water-tight design of dynamic token can be realized.
With reference to Fig. 4; Dynamic token second embodiment that the present invention is provided with the light signal output unit has been proposed; Different with first embodiment; In the present embodiment, light signal output unit 15 comprises display screen 153 and screen control module 154, and display screen 152 can be exported brightness, brightness change information, color and/or the color change information that is loaded with the data that dynamic token need export under the control of screen control module 154; Above-mentioned information can be that the brightness and/or the color of the screen of the data-modulated dynamic token that will export of the microprocessing unit 10 of dynamic token generates; Said modulation system can be modes such as amplitude modulation(PAM), phase modulated or frequency modulation(FM), and the data that said dynamic token need be exported can be cryptographic key factor or the key data that is used to generate cryptographic key factor, and this cryptographic key factor can be used to generate dynamic password.
Because dynamic token all is provided with display screen and screen control module usually, so present embodiment need not to be provided with separately light-emitting devices such as LED, promptly utilizes present device can realize sending light signal, practiced thrift cost.
When the dynamic token of present embodiment need be exported light signal, on the display screen 153 of dynamic token, show the content that needs are exported with different brightness or brightness change information or with the mode of the different information (character or numerical value) of different colors or the representative of color change information.Need the external equipment of reception information can be through brightness, brightness change information, color or the color change information of photo resistance, photodiode or phototriode induction display screen 153.The corresponding relation of brightness, brightness change information, color or color change information and the information of preserving according to external equipment itself is again handled the information that photo resistance, photodiode or phototriode are imported, and obtains the output content of dynamic token.
