Research Of Components And Security Of E-Business Platform

E-Business is an indispensable way in modern international economy and commerce and it is becoming the main trading way in 21 century gradually. So how to develop a perfect, highly reusable and secure e-Business system quickly and conveniently is a new challenge brought to enterprises by Internet era.With the development of the object technology, distributed computing technology and software engineering technology, the object-oriented component technology is becoming a mainstream technology to develop e-Business systems. The component technology makes it possible to develop a large-scale e-Business system quickly and conveniently. In this thesis, we analyze and summarize the functionality of the e-Business framework, interpret the developing method of component-based e-Business and we further bring forward a component-based e-Business software supporting platform. We also give a security architecture model of e-Business, which is the necessary guarantee for the e-Business. Within this framework, we design and implement three key components in e-Business platform: the distributed data transfer component, the LDAP-based access control component and the online payment component.As to the data integration in the supply chain inside and outside the enterprise in e-Business environment, we design and implement a distributed data transfer component DataTrans. We realize the asynchronous transfer function with good user interface between heterogeneous data sources such as Relational Database, Text files, XML files and etc, and we integrate different communication modes, such as Message Queue, Ftp, Email and etc, in which the sender and receiver are both independent. We elaborate the design and implementation of this component, describe the software architecture using UML and further discuss the application of object-oriented design pattern technology, which improves the reusability of the software greatly.In distributed environment, if there is not a perfect mechanism to authenticate the users and access control, the security of e-Business systems could not be guaranteed and the distributed agility could not be exerted sufficiently. Traditional security access control based on the database could not accommodate the application of e-Business in distributed environment. In this thesis, after analyzing the existed access control technology, we bring forward a RBAC security access control and manage model based on LDAP and design the security access control for the component DataTrans.In e-Business, security electronic payment always plays an important role in the electronic transaction. At the end, we analyze the related online payment technology, implement an online payment prototype component system based on the Java cryptography architecture and discuss the online payment component technology briefly.
