Embodiment
Below in conjunction with drawings and Examples a kind of data security storage interactive device that the utility model provides is done further introduction:
Shown in Fig. 1～6, a kind of data security storage interactive device comprises driver and storage card; The circuit board of driver is connected with storage card slot with USB interface 6, CF card contact pin and is connected, and is equipped with storage card device for fastening, storage card ejector button 4 and working station indicator 5 with storage card slot 3 is complementary.Storage card comprises CF card interface 2 and high strength shell, and high strength shell comprises loam cake, lower cover and carriage, also is equipped with inverse inserting-preventing draw-in groove 1 in storage card one side.
As shown in Figure 7, the circuit board of driver adopts the safety chip AS600 of SYNOCHIP company as primary processor, and main practical function has the realization of usb protocol, the generation of data encrypting and deciphering key, the realization of data ciphering and deciphering process, the realization that the CF interface is assisted agreement and the control of being responsible for memory card detection circuitry, condition indication circuit etc.The safety chip of driver links to each other respectively with large capacity memory chips SDRAM, CF card interface 2, duty display circuit, plug-in card state detection circuit; And large capacity memory chips SDRAM can link to each other with computing machine; Power supply provides 3.3V, 1.8V operating voltage for circuit board, and has esd protection.Large capacity memory chips SDRAM is responsible for the spatial cache of data after the release.The integrated infrared tube detection circuit of internal drive is responsible for the automatic identification of storage card.After storage card inserted driver, detection circuit sent look-at-me, and notice driver storage card inserts, and driver should transfer duty to by holding state; Extract when detection circuit detects storage card, send terminal signaling and make it transfer holding state to driver.Adopt simultaneously dual-colored LED to carry out the demonstration of duty, the duties such as effectively display driver standby, work, read-write.The USB interface 6 of driver is used for and the target machine communication, and driver can be connected with computing machine.
Memory card circuit board comprises storage chip FLASH, safety chip AS500 and fpga chip.Safety chip is the AS500 safety chip of SYNOCHIP company, and this chip has global unique hardware sequence number and as the seed of data key, and the platform that adopts fpga chip to realize as agreement.
Data storage procedure is as follows: when the user writes data in the storage card, the driver main control chip is at first write data among the SDRAM of data buffer by USB interface, then read the hardware sequence number of storage card, use the SM3 algorithm generated data in the sheet to encrypt required key, the data after then data being encrypted and will encrypting write in the FLASH chip.When the user in the storage card when read data, the driver main control chip is at first write data among the SDRAM of data buffer by the CF interface, then read the hardware sequence number of storage card, use the required key of SM3 algorithm generated data deciphering in the sheet, the data communication device after then data being decrypted and will deciphering is crossed USB interface and is issued main frame.
As shown in Figure 8, the storage card identifying is as follows:
When storage card did not insert driver, driver was in holding state.After the user inserted driver with storage card, driver transferred duty to automatic detection of stored card and by holding state.After entering duty, driver by the CF card interface encrypt data in the storage card is called in its buffer memory and the built-in aes algorithm by safety chip is decrypted.After data were finished deciphering, driver sent look-at-me to target machine, and the notification target machine begins to enumerate flow process.When enumerate finish after, the driver that has inserted storage card can be identified as the USB flash disk of a standard, the user can as the operation common U disk, carry out read-write operation to equipment.
As shown in Figure 9, it is as follows to write the storage card process:
The process that the user writes storage card can be divided into data and write and two stages of data encryption.The data write phase is not that the data in the target machine are write storage card, but the write driver internal memory.Driver memory be one with the suitable storage space of memory card capacity, data are deposited in this internal memory temporarily.When user's data writing, driver first with clear data with the stored in file format of appointment in the internal memory of driver, then call cryptographic algorithm AES data be encrypted processing, and write storage card by the CF card interface.
Reading the storage card process is: data are stored with the ciphertext form after drive encrypts in the storage card.When carrying out the storage card read operation, to deposit by the universal document system form in order to guarantee the data that target machine calls, driver is at first tackled the interior data of card and is decrypted processing.Data after the driver deciphering will be stored in the driver memory.Then, the data transmission after driver will be deciphered by USB interface is finished the Card Reader operation to target machine.
