Embodiment
Describe the preferred embodiments of the present invention in detail below with reference to accompanying drawing.
Fig. 1 illustrate according to exemplary embodiment of the present invention, for generating the flow chart of method of code of the authorization information true and false.Referring to Fig. 1, wherein represent generally according to the method for the code of the generation authorization information true and false of exemplary embodiment of the present invention with label 100.The method flow process starts to carry out from step 101.In step 101, obtain relevant information from user.More particularly, for example, can obtain from user identification information, lottery ticket choosing and selling information of user etc.Then,, in step 102, the data that obtained user profile is comprised are classified., obtained data are divided into two classes: the first kind is organization data; Equations of The Second Kind is user data.After this,, in step 103, the Ha sh value that uses the password of being inputted by user to generate is encrypted user data, to obtain user's encrypt data.In step 104, use and by the agency key of background system control, organization data is encrypted, to obtain mechanism's encrypt data.In the step 105 after step 103, generate user's encrypt data summary according to the result to ciphering user data.In the step 106 after step 104, generate mechanism's encrypt data summary according to the result that organization data is encrypted.After execution step 105 and 106, in step 107, generate the code of the authorization information true and false.More particularly, as an example, as shown in Figure 6 according to the operation of lottery sale system of the present invention in, can with specific decollator, encrypted organization data and encrypted user data be separated and add the version information of encryption expressly.That is the encrypt data that can utilize version information and described encryption to obtain afterwards comes together to generate required code.This version information can comprise cryptographic algorithm to be described.The enciphered message that formed thus has the data structure shown in Fig. 2.As previously mentioned, this Fig. 2 shows according to the schematic diagram of the data composition structure of example embodiment of the present invention.Then, formed data are encoded, to generate the required Validation Code of lottery sale system and to be kept in local storage.This Validation Code can adopt Quick Response Code or standard QR code.
As interchangeable scheme, the application according to the present invention in lottery ticket off-line verification system, can utilize the Quick Response Code that for example adds the Quick Response Code generation technique of specific scramble codes technology to generate the checking lottery ticket true and false.Exemplarily, in encrypting step, can pass through Advanced Encryption Standard (Advanced Encryption Standard, AES) or oval cryptographic algorithm (ECC) user data and organization data are encrypted.
Advanced Encryption Standard (Advanced Encryption Standard, AES) in cryptography, claims again Advanced Encryption Standard Rijndael enciphered method, is a kind of block encryption standard that U.S. government adopts.This standard be used for substitute original DES, in many ways analyzed and widely the whole world use.Through the selection flow process of 5 years, Advanced Encryption Standard was published on FIPS PUB 197 November 26 calendar year 2001 by National Institute of Standards and Technology (NIST), and became effective standard on May 26th, 2002.2006, Advanced Encryption Standard became one of most popular algorithm in symmetric key encryption already.
Oval cryptographic algorithm (ECC) is a kind of public key encryption system, is proposed at first by Koblitz and Miller two people in 1985, and its Fundamentals of Mathematics are dyscalculias of Elliptic discrete logarithm in the rational point formation Abel module of utilizing on elliptic curve.
Because the fail safe of AES is far away higher than DES, and enciphering rate is very fast, so native system preferably uses aes algorithm to carry out data encryption, key length can adopt 128, and cipher mode can adopt ECB (Electronic Code Book electronic codebook mode) pattern.
Exemplarily, can be in formed ciphertext joining day stamp in quiet data summarization, to form index information, index information and data are saved in local data base.In addition, agency key can be stored in memory, and by time rotation.
