Description
Technical field
It is specifically a kind of to be encrypted using password steganography the present invention relates to encrypting and decrypting and information steganography technical field
With the universal coded lock of decryption.
Background technique
Coded lock is the indispensable pith that personal belongings are ensured in life, and coded lock can be divided into mechanically
Coded lock and electronic type coded lock, due to the programmable feature of electronic type coded lock, the type and degree of safety of electronic password lock are just
It is being continuously improved, with the continuous development of Internet of Things, the application of electronic type coded lock will be more and more extensive.
In information encryption is learned, there is a kind of technology to be called steganography technology, this technology is to be added to bulk redundancy
In information, so that other people be allowed to obscure real information and redundancy, only know that the talent of password hidden method can be by password
It finds out and is decoded, such as, 01 bit stream can be hidden using the gray scale of picture, but picture itself seems
There is no what to change, but can be obtained by original bit stream by inverse transformation, says for another example, can be with philology
Method, by particular words whether there is or not " " as 01 distinguishing rule, by Information hiding into a book.The benefit of steganography is exactly,
On the one hand a possibility that other people observe the data containing password can be reduced, that is, is not easy to be concerned about the carrier of password,
On the other hand the difficult cracking of password can be improved by the redundancy of different form and dimension.
Therefore LED lattice display is surrounded, can be hidden by the redundancy of image using steganography really close
Code information, and combine the random scheme for generating password, even if being observed when input password by other people, other people do not know it is close
Code stowed position and password can not also be cracked in the case where decoding principle, to have compared to commonly directly inputting
The coded lock of password has higher security performance.
Summary of the invention
The purpose of the present invention is a kind of steganography coded lock of offer, the present invention use random in view of the deficiencies of the prior art
Number generation module generates random cipher under the control of processor module, and password is mapped as character according to default mapping mode
Then the motion state of dot matrix shown on LED dot matrix, unlock people needs to know preset mapping mode and by character point
The motion state of battle array cracks as password, passes through key module and inputs password, if password is identical as the random cipher of generation, seven
Segment numeral tube module display unlock successful information, and be unlocked, conversely, then showing unlock failure information.Password of the invention
Verification mode is cyclic shift verification, as long as unlock can be completed in the tandem satisfaction of password.The present invention have production it is simple,
Advantage easy to use improves the security performance of coded lock.

Embodiment
The present invention applies in this way:
Password is converted to character movement by using steganography mode by the present invention, so that coded lock not easily passs through the modes such as video recording and steals
It takes, there is stronger safety.
Refering to fig. 1, random-number-generating module 2, count using built-in counter and are transmitted to 8086 processor modules, and 8086
Processor module obtains 8 0-8 random ciphers according to count value；Seven segment numerical tube module 5, for showing man-machine interface interaction letter
Breath；LED dot array module 6, for showing that character moves, user is according to the motion conditions of character you can get it password；Keysheet module
3, user input capability is carried, mainly there is a reset button, acknowledgement key, reset button can regenerate random cipher, and acknowledgement key can be with
Confirm password currently entered；8086 processor modules 1, connect and control random-number-generating module 2, seven segment numerical tube module 5,
LED dot array module 6, Keysheet module 4, and it is responsible for the motion mode that 8 passwords are mapped as to character and the check and correction for carrying out password.
It after booting, initially enters password and generates process, click the reset button in Keysheet module, random-number-generating module generates
The random generation password of 8 0-8, and move the periodicity that random cipher is mapped as character according to mapping mode known to user
It is dynamic, and be shown in LED dot array module.Then it can enter decoding process, seven segment digital tubes first show " decode " field,
User observes the motion state decryption of character in LED dot array module, and user clicks in Keysheet module really after inputting password
Recognize key, unlock can be completed.
Specific works situation is as follows, in use, the reset button of Keysheet module is first clicked on, then 8086 processor module control
Random-number-generating module processed reads built-in counter values and to 9 modulus, to generate 8 0-8 random ciphers.Gained 8 close
Code will according to 0,1,2,3,4,5,6,7,8 corresponding static, upper, upper rights, the right side, bottom right, under, lower-left, a left side, upper left is as mapping relations
Steganography is carried out to the motion state of character, then LED lattice display module shows character and its movement.In decoding, seven number of segment
Code pipe shows " decode " field, and user is prompted to carry out password typing, and then user is closed according to the mapping of random cipher and movement
System, analysis decode that you can get it that password is unlocked.Unlocking process need to only use matrix keyboard input password and click acknowledgement key
Typing, using circulation diagnostic method when differentiating input password and the whether equal random cipher of generation, as long as the front and back of i.e. password is suitable
Sequence satisfaction can be determined as correctly, need to gradually be shifted input password with random cipher when the method is realized and be proofreaded, if moving
Then successfully decoded is proofreaded successfully behind position, if can not still match after displacement 8 times, decodes failure, and record the frequency of failure, if losing
It loses number to reach 3 times, self-locking 1 minute of processor simultaneously regenerates random cipher, prevents other people from repeatedly attempting decryption.Most
Eventually, decoding result information is shown, seven segment digital tubes show " S " if successfully decoded, if decoding failure seven segment digital tubes are shown
“F”。
