Design And Application Of Electronic Payment Protocol In Electronic Commerce

With the development and popularization of e-commerce has also been considerable progress in people's life and work, playing an increasingly important role. However, because the network itself has a variety of defects, leading e-commerce system depends on the network will also be subject to a variety of challenges. As the core element of e-commerce electronic payment, to improve its safety, practicality and efficiency are the key to promoting the rapid development of electronic commerce.This article explores a variety of typical cryptographic technology in the concrete application of electronic payments, and put forward specific proposals to address the real life of the electronic payment of certain specific issues.Firstly,on the application of e-commerce and electronic payments in a variety of data encryption techniques were studied, including symmetric and asymmetric encryption DES encryption RSA, and compare their advantages and disadvantages, made life in specific programs using a variety of data encryption.Secondly, the specific study of the digital signature, one-way Hash function, message integrity verification, zero knowledge proof and their e-commerce and electronic payments in the specific application.Thirdly, in the classic RSA blind signature electronic cash protocol based on RSA is presented based on blind signature electronic cash and the trusted third party payment protocol with revocable anonymity, can not be forged, and so can not be reused.Finally, an existing electronic cash protocol based on the design of a zero-knowledge based on blind signatures and certification of electronic cash payment system, which provides revocable anonymity and prevent unauthorized users impersonating the legitimate user application and use of electronic cash Function.
