Description
Technical field
The utility model belongs to information security field, especially relates to a kind of safety chip encryption of living body finger print identification
USB flash drive can be managed.
Background technology
USB flash disk appears on the market it may be said that helping people to solve the problems, such as electronic bits of data storage and carry well, with its corpusculum
Product large capacity, price are economical, support many merits such as hot plug and have been favored by people, and use scope has penetrated into society
All trades and professions.However USB flash disk also inevasible produces some hidden danger, such as its loss meeting while bringing people's facility
Lead to data leakage, get a short term loan the shortcomings of information loss, private can be caused company information to be caused transparent.The various data leakages of a state or party secret
Allow people to leave a question open the safety of USB flash disk, especially in the use in the concerning security matters such as military affairs, public security, business office field due to USB flash disk lose,
The leakage of a state or party secret for the reasons such as stealing also is reported in media repeatedly, causes serious loss, easily divulges a secret and easily infected virus etc. lacks
Point allows user very to have a headache.
With increasing for problems, some manufacturers, which have developed, is encrypted using software technology for USB flash disk, and what is had no need for reticence is
This method is being initially that people solve the problems, such as really.But the just so-called high ruler evil spirit in road is one zhang high, and software breaking techniques also exist
With the very fast promotion of software encryption technique in no way inferior, high speed development.Hereafter a succession of USB flash disk information leakage thing occurred
Part is even more directly to prove that USB flash disk may not prevent disclosure risk using software technology encryption, and so-called software cryptography is for stealing
It is only an ornaments to take for information personnel.USB flash disk uses hardware encryption side while abandoning software cryptography mode later
Formula so that USB flash disk has the functions such as whole district's hardware encryption to have the function that protection information is not leaked, but in current market master
The safety that the design of the hardware encrypted U disk of stream has ignored encryption hardware again and management program integrates, makes software fail and encrypt
Hardware really integrates binding, this security breaches causes quickly by the encrypted password of hack in putting into practice use, still without
Method really solves problem of divulging a secret.
Invention content
In view of this, the safety chip encryption the utility model proposes a kind of identification of living body finger print can manage USB flash drive,
Integrated management is carried out when internal (fingerprint logs in hardware encryption and uses) is with external (personal or public use) for USB flash disk, to
Prevent the generation that USB flash disk is divulged a secret.
In order to achieve the above objectives, the technical solution of the utility model is realized in:A kind of peace of living body finger print identification
Full chip encryption can manage USB flash drive, and mainboard is equipped with living body finger print sensor, safety chip, NOR FLASH, storage mould
Block and USB plug;
The living body finger print sensor, NOR FLASH, memory module, USB plug all connect the safety chip;It is described
USB plug is also connected with power module, and the power supply for the USB HOST that the electric power source pair of module USB plug is connected, which is powered, to be turned
It changes, is the living body finger print sensor, safety chip, NORFLASH, memory module power supply
Further, the power module is powered conversion using two-way AIC1952 chips, is passed all the way for living body finger print
Sensor, safety chip, NOR FLASH power supplies, another way are powered for memory module.
Further, LED light is additionally provided on mainboard, the LED light connects the safety chip.
Compared with the existing technology, a kind of safety chip encryption of living body finger print identification described in the utility model can manage
USB flash drive has the advantage that:
Have biological identification technology, realizes that living body finger print logs in by fingerprint sensor technology, and H/W has been used to encrypt skill
Art, the utility model do not need additional installation procedure, and inline cryptographic administrative skill prevents from losing leaking data, and has subregion
Management and encryption function, for USB flash disk making in internal (fingerprint logs in hardware encryption and uses) and external (individual or public use)
It is integrated and is managed with function.

Specific implementation mode
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
The utility model is equipped with the SD of living body finger print sensor 2, safety chip 1, NOR FLASH4, large capacity on mainboard
Card 3, USB plug 5 and LED light 6, power module 7;
As shown in Figure 1, safety chip P51BFN is connect with SD card 3, and living body finger print sensor is connected by UART interface
2, NOR FLASH4 are connected by SPI interface, USB jack 5 is connected by usb2.0 interfaces, connecting LED by GPIO interface refers to
Show lamp 6.
As shown in figure 3, power module 7 is powered conversion using two-way AIC1952 chips from the USB host of PC machine,
In all the way be living body finger print sensor 2 (the FP SENSOR in figure), safety chip 1 (P51BFN in figure), NOR FLASH4
(the Serial flash in figure), LED light 6 (LEDRGB in figure) are powered, and another way is powered for SD card 3.
It is the electrical block diagram of the NOR FLASH4 of embodiment as shown in Figure 4, using N25Q064A13EF640F cores
Piece accesses safety chip 1 by SPI interface.
It is the electrical block diagram of safety chip 1P51BFN in embodiment as shown in Figure 5.
As shown in Fig. 2, the operation principle of the utility model is:
The NOR FLASH4 are stored with account information, and carry out data encryption by safety chip, using SEED256 plus
Close algorithm.The management program that the NOR FLASH are used to dock the ends PC carries out account management;
The SD card is divided into conventional memory block and secure storage areas;Conventional memory block is used as common U disk;Safety is deposited
Storage area is encrypted by safety chip and is used, using ARIA256 Encryption Algorithm.Safety chip connects living body finger print sensor, with work
Body fingerprint is switched as control;The division of the routine memory block and secure storage areas carries out pipe by the management program at the ends PC
Reason.
