Description
Technical field
The utility model relates to a kind of dynamic token, belongs to information Security Protection Technology field.。
Background technology
Dynamic token is the hardware token using dynamic password, and it is that a kind of secure identity confirms product, and its storage inside has responsive information.Present stage, the method obtaining inner sensitive information is first disassembled by its housing, then by the bare spots read of sensitive information on internal circuit board.In order to protect inner sensitive information, the baroque Anti-dismounting structure of general employing now, but this Anti-dismounting structure cost is often high.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of dynamic token.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of dynamic token, comprise spill housing, battery is disposed with from the bottom up in the groove of described spill housing, token circuit board and display screen, described display screen is connected with spill housing by screw, described token circuit board is fixed on the back side of display screen, the bottom surface of described token circuit board is provided with the first conducting strip and the second conducting strip, the two ends that described first conducting strip and the second conducting strip are powered with token circuit board are respectively connected, the bottom portion of groove of described spill housing is vertically provided with the first contact rod and the second contact rod, described first contact rod and the second contact rod are relative with the second conducting strip with the first conducting strip respectively, and be connected with the positive pole of battery and negative pole respectively, the bottom portion of groove of described spill housing is also vertically provided with spring, when display screen is confined on spill housing, the top of described spring props up token circuit board, and spring is in compressive state, described first contact rod contacts with the second conducting strip with the first conducting strip respectively with the top of the second contact rod, token power on circuitry.
Described display screen is also coated with one deck peep-proof film.
Described peep-proof film also applies one deck fluid sealant.
Described battery is button cell.
Described spring is insulated spring.
Described first conducting strip and the second conducting strip are copper current-conducting piece, and described first contact rod and the second contact rod are copper contact rod.
The beneficial effect that the utility model reaches: 1, the sensitive information of dynamic token is all stored in the RAM district of token circuit chip, only under the state of continued power, sensitive information is kept at store status, once power-off sensitive information will disappear, the utility model utilizes this feature of dynamic token, token circuit board is fixed on the back side of display screen, token circuit is powered by the first contact rod and the second contact rod, lay down once display screen is split, under the action of the spring, the power supply of token circuit will disconnect, sensitive information also can disappear, effectively achieve the object of Anti-dismantling, solve the problem that existing Anti-dismounting structure cost is high, 2, display screen of the present utility model is also coated with one deck peep-proof film, effective prevents others spying on, and ensures sensitive information safety further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, a kind of dynamic token, comprise spill housing 1, battery 2 is disposed with from the bottom up in the groove of spill housing 1, token circuit board 3 and display screen 4, display screen 4 is connected with spill housing 1 by screw 5, token circuit board 3 is fixed on the back side of display screen 4, the bottom surface of token circuit board 3 is provided with the first conducting strip 6 and the second conducting strip 7, the two ends that first conducting strip 6 is powered with token circuit board 3 respectively with the second conducting strip 7 are connected, the bottom portion of groove of spill housing 1 is vertically provided with the first contact rod 8 and the second contact rod 9, first contact rod 8 and the second contact rod 9 are relative with the second conducting strip 7 with the first conducting strip 6 respectively, and be connected with the positive pole of battery 2 and negative pole respectively, the bottom portion of groove of spill housing 1 is also vertically provided with spring 10, when display screen 4 is confined on spill housing 1, the top of spring 10 props up token circuit board 3, and spring 10 is in compressive state, first contact rod 8 contacts with the second conducting strip 7 with the first conducting strip 6 respectively with the top of the second contact rod 9, token power on circuitry.
Above-mentioned spring 10 is insulated spring, and the first conducting strip 6 and the second conducting strip 7 are copper current-conducting piece, and the first contact rod 8 and the second contact rod 9 are copper contact rod, and battery 2 is button cell.
In order to prevent others spying on, ensureing sensitive information safety further, also covering one deck peep-proof film 11 on the display screen 4, peep-proof film 11 also applies one deck fluid sealant 12.
The sensitive information of dynamic token is all stored in the RAM district of token circuit chip, only under the state of continued power, sensitive information is kept at store status, once power-off sensitive information will disappear, utilize this feature of dynamic token, token circuit board 3 is fixed on the back side of display screen 4, token circuit is powered by the first contact rod 8 and the second contact rod 9, lay down once display screen 4 is split, under the effect of spring 10, first contact rod 8 and the second contact rod 9 depart from the first conducting strip 6 and the second conducting strip 7 respectively, the power supply of token circuit will disconnect, sensitive information also can disappear, effectively achieve the object of Anti-dismantling, solve the problem that existing Anti-dismounting structure cost is high.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection range of the present utility model.
