The two-dimension code content of native system has all been used the DES algorithm for encryption of self-control research and development, but not common symmetric cryptography mode is encrypted.
Symmetric cryptography refers to: symmetric encipherment algorithm is the cryptographic algorithm of using early, technology maturation.In symmetric encipherment algorithm, data transmission side makes it become complicated encryption ciphertext and sends after expressly (raw data) and encryption key are processed through special cryptographic algorithm together.After the destination receives ciphertext, if want to understand original text, need to use to encrypt with the key of crossing and the algorithm for inversion of identical algorithms ciphertext is decrypted, just can make it revert to readable plaintext.In symmetric encipherment algorithm, the key that uses only has one, send out collection of letters both sides and all use this key that data are encrypted and decipher, this will find the solution close side must know encryption key in advance, as long as the people that symmetric cryptography do a harm to have key can decipher.What native system used is not this to your cipher mode, but has used asymmetric encryption.
Asymmetric encryption refers to: asymmetrical encryption algorithm uses two complete differences but is a pair of key-PKI and the private key that mates fully.When using the asymmetrical encryption algorithm encrypt file, only have a pair of PKI and the private key of the coupling used, just can complete encryption and decryption process expressly.Adopt public key encryption during encrypting plaintext, use private key just can complete during decrypting ciphertext, and originator (encipherer) knows destination's PKI, only have destination (deciphering person) to be only unique people who knows own private key.The ultimate principle of asymmetrical encryption algorithm is, if originator wants to send the enciphered message of only having the destination to understand, at first originator must know destination's PKI, then utilizes destination's PKI to encrypt original text; After the destination receives and encrypts ciphertext, use the private key ability decrypting ciphertext of oneself.Obviously, adopt asymmetrical encryption algorithm, transmitting-receiving letter both sides are before communication, and the destination must give originator with the PKI that oneself generates at random already, and oneself keeps private key.Thereby greatly guaranteed the truly safe and effective of user profile.
The present invention has used digital signature, and the meaning of digital signature is exactly whether these data and original text comparing were revised.Be generally with the private key of oneself, data to be signed, then go to verify with PKI whether these data were revised.
Database access layer has used the DbHelperSQL class of self-control research and development, mainly effectively encapsulate substance parameter and be converted to the SQL parameter problem, having solved each data bank access method needs to create a data parametric technique, and the method that realized is general, and the specific implementation main method is as follows:
1, creating a rreturn value is SqlParameter parameter universal method, and the method need be imported three parameters into, is respectively SqlCommand, SQL statement or storing process name variable, parameter type etc.;
2, the method also need be imported three parameters into without the method for rreturn value to SqlParameter parameter assignment to create one, first parameter: SqlCommand, second parameter: correspondence database field parameter title, the 3rd parameter: the value that user object imports into.
3, the method that to create a rreturn value be SqlCommand is again called above two methods, and the method only needs an object to import value parameter into to get final product;
4, create the Universal Database method of operating, need three parameters, first parameter: SqlCommand, second parameter: carry out SQL statement or storage process title, whether the 3rd parameter: be storage process, if storage process IsProc is True, SQL statement is False.
When 5, the calling data storehouse operates universal method, need first instantiation SqlCommand, so just can solve the user when submitting data to, the fatal error of the concurrent and error in data that causes slowly because of network, call at every turn and all create a new SqlCommand object, guarantee that SqlCommand is not general, when the call parameters assignment method, the data that only need the SqlCommand that instantiation is good and the page to submit to participate in and get final product, and the SQL parameter creates that assignment is complete completes relevant database manipulation afterwards at calling data storehouse access layer.
The Cache caching technology that native system uses in product information page to server, is regularly carrying out lastest imformation to some data buffer storages, and the user does not use the database value when accession page not, effectively reduces the pressure of database and the user access that exceeds the speed limit and experiences.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
