Research And Realization Of Electronic Payment Based On Dynamic Key

After forty years of development history, the Internet technology has made the leapdevelopment, the electronic commerce also has become a daily part of everyday life. In recentyears, especially the electronic payment has the fastest development. On the one hand,because as the quality of life in national economy becoming more and more better, andeconomic transactions between each other is becoming more and more frequent, but becauseof personnel, resources or other factors restrictions, the business that can be done by the bankis very limited every day, customers waste most of time, energy in waiting for service. On theother hand, traditional financial interactive way also has many unsafe factors, such as in thepast, if you want to send sum of money to your customers who have business relations withyou, you must bring cash to the bank counter, that will give some opportunity to lawlessperson. Therefore, electronic payment be born at the right moment, and develops very rapidly.The appearance of electronic payment, to a great extent, has solved the disadvantages ofthe traditional payment. It is a product of high development of Internet technology, only withthe relation of the network and encryption technology. we can link up the ordinary commonpeople, businesses and banks, and realize "a key payment" function. As long as the externalservices by a bank, we will easily be able to realize the functions such as transfer, payment,authorized signing and so on. But because of the rise of electronic payment in not very longtime, and it is not absolute safety too. Especially in a network environment, with all kinds ofactive network hacker, once was attacked successfully, it is easy to cause the loss of property.Now, electronic payment in China was still in the initial stage, in the realization of thetraditional pay to online payment process, Banks are fragmented, and to the third-partyplatform only provide their own custom interface, have not yet to form a unified standards, sothey can’t form large payment gateway. The third payment organizations, which play the roleof middlemen between the bank and the customers are also intermingled, now half marketshare of the whole electronic payment is occupied by taobao. At the same time, the payinstitutions suchas Cai FuTong‘, quick Pay’ whichare issued licensingby national financialregulators. So, the security of electronic payment has important decision function. for thesurvival and reputation in enterprise. This paper will put forward a kind of dynamic key online payment based on AES(Advanced Encryption Standard), and uses the latest Rijndael algorithm which are passed byfederal government of the United States,it can replace the traditional electronic payment thatuses3DES algorithm. Riindael passes test by experts in the world password investigate andattack by hackers, And has been proved its excellent performance and the ability to be cracked.To get generation and distribution, of the dynamic key with it,what makes electronic paymentbecome more safe and effective. This paper mainly describes the produce process of dynamickey and the system to important framework implementation, finally to verify the feasibilityand validity of the algorithm by the experimental results.
