互联网电子支付模式研究

摘 要
互联网电子支付是电子商务的重要环节,也是电子商务高效运作的重要前提。
当前我国电子支付的应用还处在刚刚起步的阶段,各种电子支付模式都还存在安
全性或易用性上的缺陷,这也是约束电子支付发展的重要因素之一。因此,研究
当前电子支付中存在的问题,并找到相应解决方案就显得尤为重要。
本文从电子支付模式的角度入手,通过对典型电子支付模式的比较分析,总
结出了电子支付双层模型的概念,并且提出“实际支付层”是完成电子支付的根本
途径。而目前能够完成“实际支付层”的电子支付模式还存在一些缺陷,因此就需
要在已有电子支付模式的基础上加以改进,并结合我国的实际情况,设计一种新
的能够克服以往缺陷的电子支付模式。
本文创新性地提出了一种新电子支付模式,其核心是一个“集中式身份验证”
的支付中心。支付中心是在 PKI 认证体系基础上建立,其安全性与 SET 模式相近,
相比 SSL 模式而言更能够满足电子支付安全性的要求,并且无须支付者安装电子
证书及专用软件,在易用性上有所突破。本文详细描述了新的支付模式的设计理
念和工作流程,并对其运作效果、安全性等做出了评估。
我国当前电子支付模式的应用中也存在问题,由于可以完成实际支付层的支
付模式不完善,所以电子支付模式应用框架中的“骨干支付层”总体运作效率还不
高。本文在新支付模式的基础上,构想了中国电子支付模式框架的新局面。由于
本文所研究的课题是实际应用类型的,所以文章的最后一节简要地叙述了如果应
用新的互联网电子支付模式,还需要进行哪些方面的改进,提出了相应的意见和
建议。

ABSTRACT
The Electronic Payment (E-payment) is a very important part of Electronic
Commerce (EC), and it is also the premise for EC to operate effectively. Since the
application of EC in China is just beginning, every kind of electronic payment model
has its weakness from the viowpoint of security and facility, which is the main factor
that limits the application and progress of E-payment. Therefore, it is urgent to
research on E-payment, find out the problems, and get the solution.
In this paper, comparing and analyzing some kinds of E-payment model, the
author proposes the concept of two- layer model in E-payment and point out that the
essential way to conduct E-payment is true payment layer (defined by the author). But
at present the model that can achieve true payment has its weakness; therefore, based
on the present E-payment model, improvement should be made to design a new model,
which can overcome the previous weakness.
In this paper, the author proposes a new E-payment model with its core:
centralized identity validate payment center. Based on PKI, The payment center is as
safe as SET and it can also satisfy the security request of E-payment compare with SSL.
The payer doesn’t need to install digital certification and special software, so it is
easier for the payer to use. This paper describes the concept and the workflow of new
E-payment model in detail, and evaluates its operation effect and security.
There are many problems in the application of China’s current E-payment. Since
the E-payment model used to achieve true payment is not perfect, the main payment
layer of the E-payment framework cannot work effectively. On the basis of the new
E-payment model, the author proposes the new framework of China’s E-payment. As
this thesis is a applicable research, in the last part the author gives some suggestions
for the improvement if this new E-payment model is employed.
