Description
Technical field
The invention belongs to the data safety technical field of memory of mobile hard disk, and in particular to a kind of shifting based on NFC technique
Dynamic hard disk and its secure storage method of data.
Background technology
With developing rapidly for information age, safe storage demand of the people to information is increasingly paid close attention to, and is particularly certain
The reliable memory of a little confidential information, is even more related to national safety and social stability overall situation.The product of encryption storage at present is generally adopted
User identity is distinguished with the password authentication mode based on password, user is primarily due to and easily forgets password, cause to hard disk operation
Infeasibility, once secondly password leakage, it is easy to injure data safety storage.This be the deficiencies in the prior art it
Place.
Therefore, for drawbacks described above of the prior art, there is provided design a kind of mobile hard disk data peace based on NFC technique
Full storage method, to solve above-mentioned technical problem, is necessary.
The content of the invention
It is an object of the present invention to which in view of the above-mentioned drawbacks of the prior art, to provide design a kind of based on NFC technique
Mobile hard disk and its secure storage method of data, to solve above-mentioned technical problem.
To achieve the above object, the present invention provides following technical scheme：
A kind of mobile hard disk based on NFC technique, including hard disk firmware unit, it is characterised in that described hard disk firmware unit
It is connected with IC-card card reading module, hard disk and discloses area's unit and hard disk private area unit, described hard disk private area unit connection
There are DEU data encryption unit and data decryption unit；
Described IC-card card reading module reads the key components one in IC-card, the key components one with it is close in hard disk firmware unit
The synthesis of key component two uses the key of hard disk private area unit.
A kind of mobile hard disk data method for secure storing based on NFC technique, it is characterised in that comprise the following steps：
Step 1）：Electric on mobile hard disk, the hard disk of mobile hard disk discloses area's unit opening；
Step 2）：IC-card card reading module reads the key components one in IC-card；
Step 3）：The key components one that IC-card card reading module is obtained, the user right information that hard disk firmware is read in IC-card judges
Whether this IC-card has permission opening private area, if had permission, with the conjunction of key components two being stored in hard disk firmware unit
As private area key, and open hard disk private area unit and be written and read, otherwise go to step 2）.
Preferably, the step 3）In, when being written and read operation to hard disk private area unit, when to hard disk private area
When unit carries out write operation, the data to write-in are encrypted, when carrying out read operation to hard disk private area unit, to reading
Processing is decrypted in the data gone out.
Preferably, the step 3）In, hard disk private area unit is written and read after operation terminates, in addition to following step
Suddenly：
Step 4）：Hard disk is powered off, the key erasing that key components one are synthesized after being matched with key components two.Key after hard disk power-off
Erasing, rather than be present in hard disk, so as to further improve the security performance of data storage.
The beneficial effects of the present invention are can not only solve the security risks such as user password forgetting or leakage；Simultaneously
Because data encrypt storage in mobile hard disk, it can effectively prevent to steal shifting by directly disassembling the nonconventional approaches such as flash
The data message of dynamic hard-disc storage.The technical scheme had both added the convenience that mobile hard disk is used, and data storage is added again
Security.In addition, design principle of the present invention is reliable, and it is simple in construction, with application prospect widely.
As can be seen here, the present invention compared with prior art, improves with prominent substantive distinguishing features and significantly, and it is implemented
Beneficial effect be also obvious.
