Embodiment
The embodiment of technical solution of the present invention is described in detail below in conjunction with accompanying drawing.Following examples are only used for
Clearly illustrate technical scheme, therefore be intended only as example, and the protection of the present invention can not be limited with this
Scope.
Embodiment one
Fig. 1 shows the structural representation for the encrypted U disk that the embodiment of the present invention one is provided.As shown in figure 1, the encryption U
Disk, including：Main control chip 101, memory 102, usb 1 03；The main control chip 101 respectively with the memory 102,
The usb 1 03 is connected, and the usb 1 03 is connected with computer.
Wherein, the main control chip 101, for controlling the memory 102 and the usb 1 03, to the meter
The data of calculation machine do encryption and decryption process；The memory 102, the safe key for storing encryption and decryption；The USB
Interface 103, for carrying out data transmission the passage there is provided encryption and decryption with the computer.
Preferably, the memory 102 uses TSOP48 chips.
It is further preferred that the TSOP48 chips are the readable chip that can not be write.
Preferably, hiding place of safety is provided with the memory 102, the AES256 bytes that are stored with the place of safety are close
Key, the AES256 byte keys are used to realize the encryption and decryption to computer documents.During decryption, it is necessary to while it is close to possess this
Key and the encrypted U disk could be performed.
Preferably, the usb 1 03 is USB1.1, USB2.0 or USB3.0.
Based on above content, the technique effect that the embodiment of the present invention one can be realized is：The USB flash disk can utilize main control chip
101 and the encryption key that is stored therein computer documents is encrypted and decrypted, the security of increase encryption and decryption；
Place of safety is set in USB flash disk, hidden when being disconnected with computer, increases security；The USB flash disk can be with slotting with operation is just
It is prompt.
Embodiment two
To the embodiment of the present invention one accordingly, Fig. 2 shows a kind of flow of encryption method provided in an embodiment of the present invention
Schematic diagram.As shown in Fig. 2 the encryption method includes：
Step S1, in the state of the USB flash disk and computer connection, starts encryption software；
Step S2, shows the encrypted area being pre-selected and its capacity；
Step S3, it would be desirable to which the file of encryption is stored in the encrypted area；
Step S4, the file in the encrypted area is encrypted.
The technical scheme of the embodiment of the present invention two is specially：
Step S1, in the state of the USB flash disk and computer connection, starts encryption software.
First, the USB flash disk and computer are connected, it is specifically, the usb 1 03 of the USB flash disk is corresponding with computer
Usb 1 03 is connected；Secondly, the input password of USB flash disk is inputted, according to the input password, starts encryption software.Wherein, institute
The input password of USB flash disk is stated, is set when for the first time using the USB flash disk, the encryption software is previously installed in computer, when described
When USB flash disk is connected to computer, the encryption software automatically prompting user inputs USB flash disk password, and the password and USB flash disk that user is inputted
The password of middle storage is compared, and checks whether both are consistent, and input nothing is mistaken can be by the place of safety carry, and starts encryption
Program.
In embodiments of the present invention, using the means of hardware binding, only when encrypted U disk is connected with computer and inputs USB flash disk
During password, encryption method could be opened, without USB flash disk, only in the case of software, it is impossible to implement the encryption side of the embodiment of the present invention
Method, is thus greatly improved the security of encryption, after being encrypted in this way, decryption file must possess simultaneously encrypted U disk and
