Abstract


2l century , modern science and technology rapid development , the traditional business model has been able to meet more and more people demand small , e-commerce foot the inevitable trend of economic development . An important part of e - commerce enough electronic payment , electronic now more than enough electronic payment enough the cryptography research focus in recent years . Analysis has several electronic now the program be improved and combined with the new password technology designed several new , more practical electronics has the same characteristics now I program . Soil to obtain the following results : l now make the analysis of the program through an electronic design Wang Ye , pointing out its advantages and small enough , and its improvements . Deposit and registration stage to join the pre-op , shorten transaction time to improve efficiency . Divisible E 2 design a deposit line is to make the program . Authentication mechanism introduced in the program towel to prevent the the small law molecule posing user behavior of bullying | At first glance , Paul iF both identity authenticity , and therefore more suitable for large balance commercial transactions . 3 design a new , offline small so that the program can be divided into the electronics now . The design of the proxy signature and mesh signatures combined use of signature schemes with forward security cryptography to design a strong security electronic cash scheme . 4 Improved yellow design is full of divisible e- cash scheme . Join in the the Account Agreement towel pre - operation so that only banks with a trusted party cooperation in order to achieve the tracking , and therefore has a strong history of anonymous , while minimizing the loss of users . 5 improvements now make the program an offline divisible electronic . The program is characterized by the use of a secret sharing technology thinking , efficient design from a technical point of view , can be divided into electronic now I program improved effectively prevent users beforehand overpayment . 6. Design a suitable for a small , relocation easy , Divisible E online now make the program characteristics of the foot algorithm is simple , flexible and convenient , practical, strong .
