物理隔离网络环境下基于规则的数据交换方法

A Strategy-based Data Exchange Method in Physically Isolated Network Environment

企业在与外界进行信息交互的过程中,需要保证内部网络与外部网络有效的物理隔离以保障数据的安全性;为了实现在物理隔离网络环境下进行安全的数据交换,提出了一种轻便、安全的数据交换机制,该机制采用XML文件作为数据载体,可配置的交换规则带来充分的灵活性和适应性,解决了由于非实时数据交换所产生的数据冲突问题;文章从供应链管理系统的应用背景介绍入手,设计了数据交换系统的总体构架并描述了数据交换的过程,着重细述为处理数据冲突而进行的数据合并过程。

Through the whole process of information exchanging between the enterprises and their clients, the internal and external network should be isolated physically to prevent private data of enterprises from hacker＇s attacks over the Internet. In order to implement data exchange system with reliable security in physical isolation environment, it is proposed a convenient data exchange method, which uses XML file as a carrier of data. Using configurable strategy of data exchange to guarantee enough flexibility and suitability, this method resolves the data collision problem resulted from the process of non--real--time data synchronization. Beginning with introducing the background of the SCM （Supply Chain Management） system, this paper designs the overall architecture of system and represents the whole data exchange process, particularly describes the data merge process dealing with data confliction in details.
