Abstract
The invention discloses a kind of electronics instant lottery method for anti-counterfeit, and step includes: A, lottery ticket is sold, and generates random nominal value identification code；B, lottery information is subjected to encrypting storing；C, the information of reward exchange lottery ticket is subjected to operation comparison using identical encryption method, determines the lottery ticket true and false.The present invention can improve the deficiencies in the prior art, improve the anti-fake degree of electronic lottery.
Description
Technical field
The present invention relates to data encryption technology field, especially a kind of electronics instant lottery method for anti-counterfeit.
Background technique
As the development of lottery industry has developed electronic lottery on the basis of traditional paper lottery ticket.Electronic lottery
It is that purchase and prize are carried out by mobile terminal, without a kind of lottery ticket of papery material object.Due to the particularity of electronic product, pass
System paper lottery ticket anti-counterfeit measures can not apply on electronic lottery product, electronic lottery it is anti-fake become one it is urgently to be resolved
The problem of.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electronics instant lottery method for anti-counterfeit, are able to solve existing skill
The deficiency of art improves the anti-fake degree of electronic lottery.
In order to solve the above technical problems, the technical solution used in the present invention is as follows.
A kind of electronics instant lottery method for anti-counterfeit, comprising the following steps:
A, user connects lottery ticket sales server by mobile terminal and carries out lottery ticket purchase, and sales server is every to what is sold
One lottery ticket adds a random nominal value identification code；
B, the lottery information of purchase, random nominal value identification code and selling time are carried out cryptographic calculation by sales server, are added
Data after close are stored in sales server, and lottery information is sent to mobile terminal progress plaintext and is shown, by random nominal value
Identification code and selling time are sent to mobile terminal after being encoded and are shown；
C, when prize, sales server reads lottery information, random nominal value identification code and the sale stored in mobile terminal
Then time carries out cryptographic calculation identical with step B, operation result and the storage result in sales server is compared
It is right, lottery ticket is represented if result is identical as true ticket, if result difference represents lottery ticket as false tickets.
Preferably, in step B, Encryption Algorithm uses Hash function encrypting.
Preferably, Hash function used in step B is H=G1*(G2Mod n),
Wherein, H is Hash function used in step B, G1And G2For the two known Hash functions obtained at random, Mod is
Modulus operation, n are the modulus factor.
Preferably, the obtaining step of modulus factor of n are as follows:
B1, a random number a is obtained, using the absolute value of a as cycle-index to each numerical digit of random nominal value identification code
Circulation value is carried out, the numerical value in numerical digit at the end of circulation is the first intermediate value b, this step again if b=0, until b
≠0；
B2, using the numerical value of b as extract the second intermediate value c digit, since selling time number lowest order
To high-order the second intermediate value c for intercepting digit identical with b numerical value；
B3, take and distance second intermediate value c bigger than the second intermediate value c apart from nearest prime number as modulus factor of n.
Brought beneficial effect is by adopting the above technical scheme: by the present invention in that the nominal value different with every lottery ticket
Information generates encryption function, avoids failed encryption caused by encryption function is revealed.And this cipher mode makes not legal person
Even if member has stolen the encrypted data of storage from sales server, the nominal value letter of lottery ticket can not be also decoded and learnt
Breath, a possibility that realizing the uniqueness of lottery ticket decryption verification itself, prevented forgery lottery ticket.
Detailed description of the invention
Fig. 1 is the schematic diagram of first embodiment of the invention.
Specific embodiment
Referring to attached drawing, a kind of electronics instant lottery method for anti-counterfeit, comprising the following steps:
A, user connects lottery ticket sales server by mobile terminal and carries out lottery ticket purchase, and sales server is every to what is sold
One lottery ticket adds a random nominal value identification code；
B, the lottery information of purchase, random nominal value identification code and selling time are carried out cryptographic calculation by sales server, are added
Data after close are stored in sales server, and lottery information is sent to mobile terminal progress plaintext and is shown, by random nominal value
Identification code and selling time are sent to mobile terminal after being encoded and are shown；Random nominal value identification code and selling time can be compiled
For the code of bar code, two dimensional code or other achievable machine recognitions, coded sequence can be sequential encoding, or according to
The number of random nominal value identification code and selling time is carried out hybrid coding by certain rule；
C, when prize, sales server reads lottery information, random nominal value identification code and the sale stored in mobile terminal
Then time carries out cryptographic calculation identical with step B, operation result and the storage result in sales server is compared
It is right, lottery ticket is represented if result is identical as true ticket, if result difference represents lottery ticket as false tickets.
It is worth noting that, Encryption Algorithm uses Hash function encrypting in step B.
It is worth noting that, Hash function used in step B is H=G1*(G2Mod n),
Wherein, H is Hash function used in step B, G1And G2For the two known Hash functions obtained at random, Mod is
Modulus operation, n are the modulus factor.
In addition, the obtaining step of modulus factor of n are as follows:
B1, a random number a is obtained, using the absolute value of a as cycle-index to each numerical digit of random nominal value identification code
Circulation value is carried out, the numerical value in numerical digit at the end of circulation is the first intermediate value b, this step again if b=0, until b
≠0；
B2, using the numerical value of b as extract the second intermediate value c digit, since selling time number lowest order
To high-order the second intermediate value c for intercepting digit identical with b numerical value；
B3, take and distance second intermediate value c bigger than the second intermediate value c apart from nearest prime number as modulus factor of n.
By the present invention in that generating encryption function with the different ticket information of every lottery ticket, avoids encryption function leakage and lead
The failed encryption of cause.Even and if this cipher mode makes lawless people steal the encrypted of storage from sales server
Data can not also be decoded and be learnt the ticket information of lottery ticket, realized the uniqueness of lottery ticket decryption verification itself, prevented
A possibility that forging lottery ticket.And the method operand of coding is small, reduces the operation pressure of hardware.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
