The security kernel function of virtual disk；Otherwise, illustrate that U-key is to be inserted into mobile terminal for the first time, by the mark of corresponding mobile terminal
It is written in U-key, is further continued for the security kernel function of load virtual disk；S202 obtains the movement in the U-key equipment of insertion
Terminal iidentification, confirms whether the mobile terminal identification in the U-key matches with the mark for the mobile terminal being inserted into；If so,
Then continue to carry out down, otherwise, terminates the step；S203, mobile terminal identification in confirming U-key and the movement being inserted into
After the mark matching of terminal, virtual disk is locally being loaded, exclusive encrypted partition is formed.After client software is installed, pass through knot
Special U-key is closed, realizes authentication, U-key and the one-to-one binding of terminal, security performance is high, and if only if U-key passes through verification
Afterwards, virtual disk is locally just being loaded, is forming exclusive encrypted partition；When being written in encrypted partition or reading data, system is certainly
It is dynamic to carry out encryption and decryption.
Said program is advanced optimized, Fig. 2 and Fig. 4 is please referred to, in the S2 steps, has detected whether USB device
It pulls out, if so, USB device authentication unit reads the information of mobile terminal in U-key；If can read, USB device is monitored
Unit continues to execute monitoring；Otherwise, virtual disk is unloaded, the exclusive encrypted partition is invisible and unavailable.Pull out U-key
Afterwards, exclusive encrypted partition is invisible and unavailable；Encrypted state is kept after data are detached from exclusive encrypted partition, if by illegally copying
Shellfish can not still open after leaving native en, to ensure key document data safety.
As the prioritization scheme of the embodiment of the present invention, exclusive encrypted partition is specially：Document in exclusive encrypted area is certainly
Dynamic encryption；When in the exclusive encrypted partition, the document can equally be opened, edit and preserve with normal file, when
It is illegally duplicated when leaving native en, the document can not be opened, to ensure the safety of key document data.Preferably,
Document includes the document of newly-built document and copy, and the document that either newly-built document still copies can obtain exclusive add
The protection of close subregion, and when be illegally duplicated leave native en when, also all can cause the document that can not open.
As the prioritization scheme of the embodiment of the present invention, S5 steps are specially：Scanning filtering upper layer application is to data in disk
Operation, it is described operation include read or be written；Judge whether the operation carries out in virtual disk, if so, to write-in
The data of virtual disk are encrypted, and otherwise, the data to reading virtual disk are decrypted.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
