Description
Technical field
The utility model relates to a kind of dynamic token of Anti-dismantling, 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
The utility model provides a kind of dynamic token of Anti-dismantling, solves the problem that existing Anti-dismounting structure cost is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of dynamic token of Anti-dismantling, comprise spill housing, be successively set on the battery in spill housing groove from the bottom up, token circuit board and display screen, described spill housing is provided with the first screw hole and the second screw hole, described display screen is provided with the through hole mated with the first screw hole and the second screw hole, described spill housing and display screen are fixed by the first conduction screw and the second conduction screw, the two panels conducting strip at interval is provided with in the first screw hole fixing the first conduction screw and the second screw hole fixing the second conduction screw, first conduction screw is screwed into two panels conducting strip in the first screw hole and all conducts electricity screw with first and recline, second conduction screw is screwed into two panels conducting strip in the second screw hole and all conducts electricity screw with second and recline, the two ends powered for token circuit board are connected with a slice conducting strip in the first screw hole and a slice conducting strip in the second screw hole respectively, another sheet conducting strip in described first screw hole is connected with the positive pole of battery, another sheet conducting strip in described second screw hole is connected with the negative pole of battery.
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 first conduction screw and the second conduction screw are brass screws.
Described conducting strip is copper current-conducting piece.
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, be arranged to the screw being used for fixing conduct electricity screw, the power supply of token circuit board is by conduction screw, once conduction screw is turned on, will power-off, sensitive information also can disappear, and effectively achieves the object of Anti-dismantling.2, the utility model structure is simple, with low cost; 3, display screen of the present utility model is also coated with one deck peep-proof film, effective others spying on anyway, ensures sensitive information safety further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is vertical view of the present utility model.
Fig. 3 is the structural representation of the first conduction screw and conducting strip.
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 illustrated in fig. 1 and 2, a kind of dynamic token of Anti-dismantling, comprise spill housing 1, be successively set on the battery 2 in spill housing 1 groove from the bottom up, token circuit board 7 and display screen 3, spill housing 1 is provided with the first screw hole and the second screw hole, display screen 3 is provided with the through hole mated with the first screw hole and the second screw hole, display screen 3 is also coated with the peep-proof film 9 that one deck prevents others from spying on, peep-proof film 9 also applies one deck fluid sealant 4, spill housing 1 and display screen 3 are fixed by the first conduction screw 5 and the second conduction screw 6, first conduction screw 5 and the second conduction screw 6 are brass screws, the two panels conducting strip 8 at interval is provided with in the first screw hole fixing the first conduction screw 5 and the second screw hole fixing the second conduction screw 6, conducting strip 8 is copper current-conducting piece, first conduction screw 5 is screwed into two panels conducting strip 8 in the first screw hole and all conducts electricity screw 5 with first and recline, second conduction screw 6 is screwed into two panels conducting strip 8 in the second screw hole and all conducts electricity screw 6 with second and recline, concrete structure as shown in Figure 3, the two ends powered for token circuit board 7 are connected with a slice conducting strip 8 in the first screw hole and a slice conducting strip 8 in the second screw hole respectively, another sheet conducting strip 8 in first screw hole is connected with the positive pole of battery 2, another sheet conducting strip 8 in second screw hole is connected with the negative pole of battery 2, this battery 2 can be button cell.
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, above-mentioned dynamic token utilizes this feature of dynamic token, is arranged to the screw being used for fixing conduct electricity screw, and the power supply of token circuit board 7 is by conduction screw, once conduction screw is turned on, will power-off, sensitive information also can disappear, and effectively achieves the object of Anti-dismantling.
