The utility model is achieved through the following technical solutions:
A kind of information encryption memory storage comprises: storer, storage encryption information of software encrypting module, communication interface modules, wherein, communication interface modules is connected with storer by the information encryption module.
For information can be read by its correct user when reading, the utility model comprises that also one is used for the IC-card of authentication, the data-interface of this IC-card is connected with the IC-card interface of information encryption module, and the information encryption inside modules stores and the identical numbering of IC-card numbering.
Described information encryption module is FPGA (field programmable gate array, gate array can be compiled in the scene) or CPLD (complex programmable logic device, compound programmable logic device (PLD)).
Storer in the utility model can be FLASH MEMORY, also can be SDRAM, also can be EEPROMA, can also be formed by they combination in any.
Communication interface modules comprises interconnective communication interface control chip and communication interface, wherein, the data-signal of communication interface is connected with the data-signal of control chip, the data output signal of control chip is connected with the data input signal of information encryption module, and communication interface is connected with outer computer.
Between communication interface modules and information encryption module, be connected with the ATAPI/IDE expansion interface circuit.
Communication interface described in the utility model is USB interface or parallel interface or IEEE1394 interface.
When being written to the data in the computing machine in the storer, the encryption system that is stored in the information encryption module at first will carry out authentication, when the numbering of IC-card be solidificated in wherein numbering when identical, these data at first are written in the information encryption module by communication interface and control chip, encrypt, then output in the storer and preserve by the information encryption module, as the numbering of IC-card with solidify numbering when inequality, the operation that can not write; When reading of data from storer, encryption system still at first carries out authentication, when the numbering of IC-card be solidificated in wherein numbering when identical, these data output in the information encryption module, are decrypted, again by control chip and communication interface output.
In sum, the information of storer reads or writes all will pass through the processing of the information encryption module that stores encryption software, make information safer and personalized, and have only the user to use my IC-card, just can write and read the information in the hard disk, strengthen the security of information greatly.
Description of drawings
Fig. 1 is a structural principle block diagram of the present utility model;
Fig. 2 is the theory diagram of an embodiment in the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:
Referring to Fig. 1, be structural principle block diagram of the present utility model, the utility model comprises communication interface modules 21, stores the information encryption module 22 of encryption software, storer 23, IC-card 24, wherein, communication interface modules 21 comprises interconnective communication interface 210 and control chip 211, communication interface 210 is connected with computing machine 10, control chip 211 is connected with information encryption module 22, and information encryption module 22 is connected with storer 23, and information encryption module 22 is connected with IC-card 24 by data-interface.
Between control chip and information encryption module 22, an ATAPI/IDE expansion interface circuit can also be set, the data-interface of control chip 211 is connected with the ATAPI/IDE expansion interface circuit, and the ATAPI/IDE expansion interface circuit is connected with the Data Input Interface of information encryption module.
Before to the utility model operation, at first to carry out authentication, in the utility model, adopt the mode of IC-card authentication, because in encryption system, unique storer numbering is solidificated in the information encryption module 22, each IC-card is corresponding with a unique numbering, has only when the numbering of this storer is consistent with the numbering of IC-card and just can open storer, the operation that canned data is read or writes.
