The method has the advantages that the application method with multiple passwords is provided, the automatic password identification of the lock is realized, and the safety of the coin inserting machine is improved.
Description
Technical field
The present invention relates to a kind of data ciphering method, especially relate to a kind of slot machine used in bus unlocking cipher encryption method.
Background technology
The password that on existing bus, slot machine is unblanked is that a fixing password divide into multistage, and having multiple people to preserve (namely a people preserves one section of password), when unblanking, inputted in order in handle by multistage password, is also that many people input during input.This single cipher is divided into the form of unblanking of many groups, just a kind of cipher mode, and considering may the data of person who is ambitious or tenacious of purpose when intercepting communication, and only need to crack an infill layer, the form of single password is easily stolen, and there is potential safety hazard.
Summary of the invention
In view of this, the object of this invention is to provide a kind of slot machine used in bus unlocking cipher encryption method, propose the application process of many passwords, reach the function of the automatic recognition code of lock energy, improve slot machine degree of safety.
For achieving the above object, the present invention by the following technical solutions:
A kind of slot machine used in bus unlocking cipher encryption method, wherein, comprises the steps:
Step 1, arranges and organizes unlocking cipher more; Multiple cipher is distributed to multiple people to preserve, everyone preserves one group of password;
Step 2, multiple cipher all inputs in handle, and is numbered this multiple cipher, often organizes codon pair and answers a numbering;
Step 3, handle is by multiple cipher input lock;
Step 4, multiple cipher is carried out first time encryption by handle respectively, and cryptographic algorithm formula is: b
n=f
n(a
n), n is the group number of password, a
nbe n-th group of password, b
nfor cryptographic secret, f
nfor cryptographic algorithm; Often organize the cryptographic algorithm f of password
nall not identical;
Step 5, when unblanking, by lock random selecting one numbering, and sends the option code of selected numbering to handle;
Step 6, handle carries out second time encryption according to the option code received to one of corresponding numbering group of password, and sends ciphertext d to lock
n=f (b
n), b
nfor cryptographic secret, f is unified cryptographic algorithm, d
nfor cryptographic secret;
Step 7, obtains decodement after being locked into row twice deciphering.
The invention has the beneficial effects as follows:
The present invention changes single password of the prior art into many cryptogram form, and handle can store multiple cipher, and is numbered to each group password, and lock can be unblanked according to the numbering passwords of random selecting, obtains decodement by twice deciphering.It is random for often organizing choosing of password, selects by locking, instead of handle.Like this, if monitored the data of handle and lock by technological means, because the communication data of handle and lock is cryptographic secret, can guarantee that the decodement of each communication is all different, increase the difficulty cracked.
Accompanying drawing explanation
Fig. 1 is method flow diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, of the present inventionly to comprise the following steps:
Step 1, arranges and organizes unlocking cipher more; Multiple cipher is distributed to multiple people to preserve, everyone preserves one group of password;
Step 2, multiple cipher all inputs in handle, and is numbered this multiple cipher, often organizes codon pair and answers a numbering;
Step 3, handle is by multiple cipher input lock;
Step 4, multiple cipher is carried out first time encryption by handle respectively, and cryptographic algorithm formula is: b
n=f
n(a
n), n is the group number of password, a
nbe n-th group of password, b
nfor cryptographic secret, f
nfor cryptographic algorithm; Often organize the cryptographic algorithm f of password
nall not identical;
Step 5, when unblanking, by lock random selecting one numbering, and sends the option code of selected numbering to handle;
Step 6, handle carries out second time encryption according to the option code received to one of corresponding numbering group of password, and sends ciphertext d to lock
n=f (b
n), b
nfor cryptographic secret, f is unified cryptographic algorithm, d
nfor cryptographic secret; What no matter lock was selected is that option code, and handle can be all that cipher code set adds one deck password again with unified cryptographic algorithm f before being transmitted;
Step 7, obtains decodement after being locked into row twice deciphering.Prestore corresponding decipherment algorithm in lock, be decrypted according to decipherment algorithm, obtain decodement.
The present invention is that the password of unblanking has many groups for the embodiment of the application process of this many passwords, and everyone inputs one group, and this multiple cipher is all input in handle, and this time just exists multiple cipher in handle, and is numbered this multiple cipher.By handle, whole multiple ciphers is input in lock, the program of a lock the inside design random selecting password, when handle is unblanked, a certain group of password in lock random selecting handle, and identify that this group password is as the password of unblanking, and could unpack when this group password is correct.It is random for often organizing choosing of password, selects by locking, instead of handle.
The program of a random selecting numbering passwords is write in lock, write multiple cipher in the handle and be numbered to these passwords, when handle is unblanked, lock can be selected one at random and number the numbering of then mating in handle, and unblanks with the password of this numbering.The group of password is several determines according to actual conditions, in the present embodiment, suppose there are 4 groups of passwords, these 4 groups of passwords are respectively a1, a2, a3, a4, after these 4 groups of passwords are written to handle, handle can be encrypted decodement according to the algorithm of correspondence, and each group password all can have an one's own algorithm, the cryptographic secret deposited in concrete handle, namely b1, b2, b3, b4 are as follows:
b
1＝f
1(a
1)；
b
2＝f
2(a
2)；
b
3＝f
3(a
3)；
b
4＝f
4(a
4)；
Wherein f
1, f
2, f
3, f
4represent different algorithms.
When handle will be unblanked, lock first sends the option code of selected numbering to handle, then handle gives lock transmission a cryptographic secret according to option code, can encrypt one deck again before being transmitted, d in data
n=f (b
n), this algorithm (f is unified algorithm) is the same, and what no matter lock selection is that option code, and handle all can add one deck password before being transmitted again.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, other amendments that those of ordinary skill in the art make technical scheme of the present invention or equivalently to replace, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
