Abstract
The invention discloses an encryption method supporting a mobile media. According to the method, encryption and decryption functions are solidified on the mobile media whose functions are protected by an authentication mode. Compared with the traditional method in which the encryption and decryption functions must be installed on a PC terminal, the method of the present inventyion is more convenient in that the mobile media is easier to carry. When a user needs to work in different locations, files require no decryption for that encrypted files can be directly transmitted on the internet without the worry of risk of secret leakage; when the user come to a different location, the mobile media can be connected with any one of PC terminals for the user to use the encrypted files.
Description
Technical field
The invention belongs to the computer information safety technique field, relate in particular to a kind of encryption method of supporting move media.
Background technology
At present, the data protection to movable memory equipment (as: portable hard drive, USB flash disk, SD card, CD etc.) generally has following several kinds of modes.The one, the data message itself that is stored in the move media is encrypted, but this generally only is applicable to personal behavior that for company or enterprise, this is unfavorable for going on business or goes out office.The 2nd, prevent the leakage of data of move media through concealed encrypted partition and PKI technology, but this mode exists and is still in the medium expressly, with the mutual process of other-end in plaintext transmission also very easily cause and divulge a secret.
Summary of the invention
The present invention provides a kind of encryption method of supporting move media, utilizes the mobile phone hardware numbering scheme to make user's certificate, makes certificate have uniqueness, is kept at encrypt file more not to be cracked in the mobile phone EMS memory card or to duplicate, and realizes the security of information preferably.
To achieve these goals, the present invention adopts following technical scheme:
A kind of encryption method of supporting move media, wherein, said method step comprises:
A1: memory module is comprised that authentication module, curing module, core driver module etc. are solidificated on the move media in advance.
A2: move media is connected with terminals such as PC.
A3: the core driver module is sensed and is connected the also chip of activating and authenticating module.
A4: authentication module starts, and requires the user to carry out authentication.User through authentication can use or visit in the move media all the elements.The user through authentication or authentication mistake can't not visit the encryption and decryption functions that move media also can't use move media to provide.
A5: after authentication, core driving module drives information loads and the injection user terminal.
A6: after activation bit successfully loads,, and realize it is carried out the function of transparent encryption and decryption through curing module with the data on the monitoring terminal.
A7: after breaking off connection, load the activation bit that is injected into the terminal and respond to also unloading/deletion activation bit automatically, the file of will not close is simultaneously closed automatically.
A8: after breaking off connection, the user can not use or visit the content of storing in the move media.
A9: after break off connecting, enciphered data, the file of user on can not access terminal.
The used cipher mode of said method is a symmetry or asymmetric.
Said core driver module can be responded to being connected of move media and terminal.
Said core driver module can the activating and authenticating module carry out authentication.
Said core driver module can and inject activation bit to terminal loads, activates calling program in the curing module simultaneously.
The activation bit of said loading and injection can be responded to and unloading/deletion activation bit automatically after break off connecting, and the file of will not close is simultaneously closed automatically.
After breaking off being connected of move media and terminal, can not use or visit the content of storing in the move media, also can't use or visit the encrypted content at terminal self in the move media.
A kind of encryption method of supporting move media provided by the invention is cured to encryption and decryption functions on the move media, and by certification mode function own is protected.Must encryption and decryption functions to be installed to the PC terminal more convenient than traditional for this method; Move media is carried more easily; When needs when various places go to office, need be with file decryption yet, cryptograph files can be directly in internet transmission and the risk of not worrying divulging a secret; When the strange land, any station terminal can through with the use of carrying out cryptograph files that is connected of move media.

Embodiment
Specify the present invention below in conjunction with accompanying drawing, it explains principle of the present invention as the part of this instructions through embodiment, other aspects of the present invention, and characteristic and advantage thereof will become very clear through this detailed description.
Like Fig. 1, shown in 2, A1: memory module is comprised that authentication module, curing module, core driver module etc. are solidificated on the move media in advance.
A2: move media is connected with terminals such as PC.
A3: the core driver module is sensed and is connected the also chip of activating and authenticating module.
A4: authentication module starts, and requires the user to carry out authentication.User through authentication can use or visit in the move media all the elements.The user through authentication or authentication mistake can't not visit the encryption and decryption functions that move media also can't use move media to provide.
A5: after authentication, core driving module drives information loads and the injection user terminal.
A6: after activation bit successfully loads,, and realize it is carried out the function of transparent encryption and decryption through curing module with the data on the monitoring terminal.
A7: after breaking off connection, load the activation bit that is injected into the terminal and respond to also unloading/deletion activation bit automatically, the file of will not close is simultaneously closed automatically.
A8: after breaking off connection, the user can not use or visit the content of storing in the move media.
A9: after break off connecting, enciphered data, the file of user on can not access terminal.
The used cipher mode of said method is a symmetry or asymmetric.
Said core driver module can be responded to being connected of move media and terminal.
Said core driver module can the activating and authenticating module carry out authentication.
Said core driver module can and inject activation bit to terminal loads, activates calling program in the curing module simultaneously.
The activation bit of said loading and injection can be responded to and unloading/deletion activation bit automatically after break off connecting, and the file of will not close is simultaneously closed automatically.
After breaking off being connected of move media and terminal, can not use or visit the content of storing in the move media, also can't use or visit the encrypted content at terminal self in the move media.
The said safe movement medium of this method, its carrier can be portable hard drive, USB flash disk, SD card, CD etc.This medium also comprises authentication module, curing module, core driver module except that original memory function module, transport function etc.
