Abstract
The invention discloses a kind of file encrypting method based on computer machine code, for file in LAN system internal cryptographic transmission, comprise the steps: 1) in LAN system, it is respectively provided with file producing unit, file distribution unit, file reception unit；2) file made and computer machine code thereof are uploaded in the authorization database of file distribution unit by described file producing unit；3) described file distribution unit computer machine code of extraction document recipient from authorization database, makees nonequivalence operation by this computer machine code with encrypting file step-by-step, generates encryption file, is handed down to file reception unit；4) encryption file is decrypted by described file reception unit by installing filter Driver on FSD.This encryption method is by utilizing txt document to be tested, and file in LAN system internal cryptographic transmission, effectively prevent data and is hacked and the problem that is stolen or gives away secrets.
Description
Technical field
The present invention relates to file ciphering technology, transmitted particularly for file at LAN system internal cryptographic
Plant file encrypting method based on computer machine code.
Background technology
Machine code refers to a string serial number formed by hardware sequence number through a series of encryptions, hash；Hard disk, CPU
There is an identification code that cannot revise.The MAC of network interface card the most also calculates one, but it can artificially be revised.Machine code is
Being produced by computer hardware information, will not change, if formatting hard disk or refitting system, may change.If having suffered disease
Poison, then be likely to change.Under normal circumstances, the machine code that we take is from hard disk, mainboard or CPU, when these three hardware
Machine code may be caused during change to change and need to re-register, other hardware changes the most not to be affected.The most topmost
Being hard disk, generally the change of hard disk is required for re-registering.Mainboard and CPU only have just use under the few cases.?
Information transmission during, the harm existed is mainly man-in-the-middle attack (MITM), including SMB Session Hijack, DNS deception,
The modes such as proxy server, by intercepting normal network communication data, and carry out data tampering and sniff, and the both sides communicated
But know nothing.Its harm is embodied in: when host A communicates with host B, all " to forward " for it by host C, and between A, B
The not directly communication on real meaning, the information between them transmits and completes as intermediary with C, but A, B without
It is realized that and think between them it is in directly communication.So attacking main frame and become a transponder in centre, C can not
Only eavesdropping the communication of A, B to distort information and pass to the other side again, fallacious message just can be passed to A, B to reach by C
Purpose to oneself.When A, B communicate, C the most actively goes " to forward " for it, simply the data backup of their transmission, to obtain
Taking the activity of user network, including the sensitive information such as account, password, this is that passive aggression is also very difficult to be found.
Summary of the invention
The technical problem to be solved in the present invention is: how to utilize machine code to realize encryption and transmits, is attacked solving data
The problem hit and be stolen or give away secrets.
To achieve these goals, the concrete technical scheme that the present invention takes is: a kind of file based on computer machine code
Encryption method, for file in LAN system internal cryptographic transmission, comprises the steps:
1) in LAN system, it is respectively provided with file producing unit, file distribution unit, file reception unit；
2) file made and computer machine code thereof are uploaded to the mandate number of file distribution unit by described file producing unit
According in storehouse；
3) described file distribution unit computer machine code of extraction document recipient from authorization database, by this computer machine code
Make nonequivalence operation with file step-by-step need to be encrypted, generate encryption file, be handed down to file reception unit；
4) encryption file is decrypted by described file reception unit by installing filter Driver on FSD.
Further, step 2) in, described file distribution unit, after generating encryption file, is opened at encryption filename
Head increases " JM " two letters, is handed down to file reception unit.For filtering handsome choosing encryption file.
Further, in step 4), described decrypting process comprises the steps:
A, described file reception unit pass through filter Driver on FSD, intercept and capture the file that file initial is " JM "；
B, " file reading " operate in, utilize computer machine code by file data send into buffered district；
C, " file is write " operate in, utilize computer machine code by file data re-encrypted write disk.
Compared with prior art, the invention has the beneficial effects as follows: this encryption method is surveyed by utilizing txt document
Examination, file in LAN system internal cryptographic transmission, effectively prevent data and is hacked and the problem that is stolen or gives away secrets.
Accompanying drawing explanation
Fig. 1 show the flow chart of the present invention.
Detailed description of the invention
In conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in detail, so that skilled artisan understands that this
The technology design of invention.
A kind of file encrypting method based on computer machine code, for file at LAN system internal cryptographic transmission, bag
Include following steps:
1) in LAN system, it is respectively provided with file producing unit, file distribution unit, file reception unit；
2) file made and computer machine code thereof are uploaded to the mandate number of file distribution unit by described file producing unit
According in storehouse；
3) described file distribution unit computer machine code of extraction document recipient from authorization database, by this computer machine code
Make nonequivalence operation with file step-by-step need to be encrypted, generate encryption file, be handed down to file reception unit；
4) encryption file is decrypted by described file reception unit by installing filter Driver on FSD.
Further, step 2) in, described file distribution unit, after generating encryption file, is opened at encryption filename
Head increases " JM " two letters, is handed down to file reception unit.For filtering handsome choosing encryption file.
Further, in step 4), described decrypting process comprises the steps:
A, described file reception unit pass through filter Driver on FSD, intercept and capture the file that file initial is " JM "；
B, " file reading " operate in, utilize computer machine code by file data send into buffered district；
C, " file is write " operate in, utilize computer machine code by file data re-encrypted write disk.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any amendment, equivalent and the improvement etc. made within god and principle, should be included within the scope of the present invention.
