4, chip encryption measure: promptly by on mobile memory, installing the encryption chip device additional,, memory bank is encrypted, on memory bank, plugged USB KEY during use and realize deciphering, pull up USB KEY and realize encrypting by cryptographic algorithm.This kind encryption measures is safety encipher measure.Drawback: cost height; Can only realize overall encryption, plug USB KEY after, totally deciphering, no file encryption level; The vision of product own intuitively can find it is to encrypt memory bank, and there is enciphered message inside, has caused that the stranger pays close attention to.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of RF radio frequency induction mode of passing through and hides or display part storage space storing mechanism.
The technical scheme in the invention for solving the technical problem is: a kind of RF radio frequency induction mode of passing through is hidden or display part storage space storing mechanism, comprise memory device, radio frequency induction module and authenticate device, described storing mechanism also comprises encrypting and decrypting input and output control chip, the radio frequency induction module is connected with encrypting and decrypting input and output control chip, encrypting and decrypting input and output control chip is connected with memory device, and encrypting and decrypting input and output control chip is provided with and the outside interface that is connected.
Described encrypting and decrypting input and output control chip is USB2.0 with the outside interface that is connected.
Hide important file for convenience, described memory device is divided into encrypted area and non-encrypted area, and described encrypted area is the concealed-enciphering district.
The interface that described encrypting and decrypting input and output control chip links to each other with memory device is the SATA interface.
The beneficial effects of the utility model are: realized encrypting hiding of space; comparative benefits: the hard disk that other cipher modes are encrypted; it is encrypted that unauthorized people recognizes hard disk easily; information is protected; in case unauthorized people knows about the needs of protected information; both can adopt various means to realize target; such as violence; coerce owner's public information of hard disk; or by technological means realization deciphering; but the memory device that adopts present technique to encrypt, encrypted area is to be stealthy nonrecognition state under unauthorized, unauthorized people is unaware of the existence of encrypted area in addition at all; the ID of authentication usefulness itself is encrypted by AES 128bit, is difficult to crack.

Embodiment
A kind of as shown in Figure 1 RF radio frequency induction mode of passing through is hidden or display part storage space storing mechanism, comprise memory device 3, radio frequency induction module 1 and authenticate device 7, described storing mechanism also comprises encrypting and decrypting input and output control chip 2, radio frequency induction module 1 is connected with encrypting and decrypting input and output control chip 2, encrypting and decrypting input and output control chip 2 is connected with memory device 3, and encrypting and decrypting input and output control chip 2 is provided with and the outside interface 6 that is connected; Described memory device 3 is divided into encrypted area 4 and non-encrypted area 5; Described encrypted area 4 is concealed-enciphering districts.
The authenticate device 3TAG KEYS (ID) that each movable storage device 3 coupling needs when two authentications are arranged, each ID is unique, before movable storage device 3 is encrypted, system will write down two the unique ID of this memory device 3 couplings and the sequence number of memory device 3, and be stored in the sequence number storage medium authentication identification when being used for external use after above-mentioned information encrypted with AES 128bit.
Authentication information is not to exist in the memory device 3, neither exist on the PC, but existed in the sequence number storage medium, only use by special instrument and just can read, but owing to adopted AES 128bit to encrypt, even adopted speciality tool to read authentication information, also be mess code information, so this authentication information have safety assurance by unauthorized user.
The KEY of the data encryption in the movable storage device 3 is that two ID and the hard disk sequence number encrypted by AES 128bit generate jointly.
Obtain authenticating the KEY that the back generates the data encryption in the movable storage device 3 the user, this KEY is neither existed in the computing machine, do not existed in the hard disk (to comprise the sequence number storage medium) yet,, can not be read the value of this KEY yet even other people spy upon the hard disk sequence number.
Data in the movable storage device 3 are pressed sector encryption by this KEY with non-standard algorithm.
Be divided into two districts during with movable storage device 3 initialization, 5, one of a non-encrypted area is an encrypted area 4, and authenticate device 3TAG KEY only implements authentication to the use of encrypted area 4.After movable storage device 3 connects PC, under non-authentication state, PC can only recognize non-encrypted area 5, the user can arbitrarily use this zone, promptly shows this non-encrypted area 5 in " my computer " window of PC, and non-encrypted area 5 does not show, and in " disk management " window, also do not show to have encrypted area 4, even adopt any software all can not inquire the existence of encrypted area 4, encrypted area 4 is in hidden state.
But after movable storage device 3 connects PC, induction TAG, after the ID authentication, the user not only can arbitrarily use non-encrypted zone, and can use and encrypt the zone, promptly in " my computer " window of PC, show non-encrypted area 5 and 4 two icons of encrypted area simultaneously.
Memory device 3 comprises the memory storage that external hard disk, flash disk, SSD etc. are connected with computing machine by external interface 6, and its interface is the standard of total interfaces such as USB2.0, USB3.0,1394, SATA, HDMI.
Use step of the present utility model is as follows:
1, before the product export, by the movable storage device 3 of factory initialization employing RF induction technology, and related two unique authenticate device 7 TAG KEY (ID).
2, set the size of encrypting storage space by special software, so far be provided with and finish.
3, after the user connects computing machine with this movable storage device 3; computing machine can recognize non-encrypted area 5; at this moment can't discern the storage space of RF induction protection; not only in " my computer " window, can't see by the storage space of RF induction protection, and in disk management, also can't discern the storage space of RF induction protection.
4, when with authenticate device 7 (TAG KEY) near movable storage device 3 after, be installed on authenticate device 7 received signals on the radio frequency induction module 1, show that encrypted area 4, computing machine can recognize by the storage space of RF induction protection.
5, when once more with authenticate device 7 (TAG KEY) near movable storage device 3 after, be installed on authenticate device 7 received signals on the radio frequency induction module 1, concealed encrypted district 4, computing machine can't be discerned by the storage space of RF induction protection.
6, after the storage space computer Recognition of being protected by the RF induction, the pilot lamp of movable storage device 3 is shown in green.
After having used the utility model, national security personnel go out to fetch confidential information, exist in the encrypted area, when this memory bank is taken by unauthorized people, discern less than encrypted area at all, can only see the information of non-encrypted area, have guaranteed Security Officer's safety.Confidential data is stored in transmittance process in the encrypted area 4, in case lose, unauthorized people has no way of finding out about it and has encrypted area, and the safety of data is guaranteed.User's sensitive information is stored in encrypted area, even memory bank is given unauthorized people, because unauthorized people can not know encrypted area 4, sensitive data is safe.
