【摘要】 随着互联网的迅速发展与流行，人们希望借助于互联网完成的事情也越来越多。近年来，利用互联网进行电子商务是受到人们普遍关注的焦点。然而，在电子商务中最核心而且最重要的是要保证有一个安全、有效的电子支付环节，因此，研究一个安全、有效的电子商务支付系统非常重要。 本文立足于国内电子商务自身发展的需要，研究了目前国内建立在SSL(Secure Sockets Layer)协议和SET(Secure Electronic Transaction)协议基础之上的电子商务支付系统的特点。在分析这些特点基础之上，指出了目前国内在基于SSL协议的支付系统及SET支付系统中电子钱包(SET支付系统中持卡者端的软件)存在的不足，并分别设计与实现了一个基于SSL协议的安全代理系统及基于服务器的电子钱包系统。 其中，建立在SSL协议基础之上的安全代理系统，打破了国外对国内加密密钥长度的限制，并提供了数字签名服务，能够很好的为我国电子商务的安全交易服务。此外，本文实现的基于服务器的电子钱包与国内现有的电子钱包相比，对于持卡者来说，具有便携性、安全性、方便性、实用性等好的特性。因此，它能够更好的为用户服务，从而能够有力的推动基于SET协议的电子商务应用解决方案在国内的推广。更多还原

【Abstract】 With the rapid development and population of the Internet, people became more and more relied on it. In recent years, using Internet for e-commerce attracted many people’s attention. The core of e-commerce, the subsystem of safe and efficient e-payment is the crucial problem to an e-commerce transaction. Therefore, the research on security and efficient e-commerce payment system is of great importance.With the goal to meet the requirement of Chinese e-commerce development, this paper analyzes the characteristics of the existing e-commerce payment systems based on the SSL (Secure Sockets Layer) protocol and SET (Secure Electronic Transaction) protocol that are widely used in china. In this paper, it pointes out the disadvantage of those SSL-based payment systems and the e-wallet in a SET payment system. Furthermore, it describes a new model of the design and implementation of an SSL-based security proxy system and a server-based e-wallet system to improve those disadvantages.The SSL-based security proxy system breaks the blockage of the encrypt-key-length limitation set by some foreign products and provides the digital signature to the native secure e-commerce transaction. As well, the server-based e-wallet has the advantages of mobility > security > convenience> practicality comparing with the current e-wallets currently used in China. Therefore, it can provide a better service to the e-wallet user and can greatly promote the population of SET-based e-commerce application solution in China.更多还原
