【摘要】 随着世界经济全球化和一体化的发展,电子数据交换已成为企业参与贸易竞争的重要手段。传统的EDI交换方式的技术复杂及费用要求过高等诸多不利因素,使得在中小企业中实施起来比较困难。XML以其高度结构化和跨平台等诸多优势,解决了以前数据交换中许多棘手的问题。做为一种好的数据交换中介格式,XML正成为企业内部或企业间交换数据的首选。不过由于XML是纯文本文件,且文件本身也过于臃肿使得XML文件在传输过程中的安全性和传输效率方面值得重点关注。在目前国内XML应用正在兴起,数据交换标准不统一的条件下,本系统对于企业内部或企业间方便、安全、高效地交换数据提供了一定的理论依据和现实意义。本文首先对数据交换的发展进行了讨论,并分析了XML的安全性问题。接着简述了XML语言本身,论述了XML安全的基本原理,包括XML加密和签名。然后通过XML与关系数据库之间的关系,解决了XML数据交换前后XML与数据库之间相互转换问题。然后,设计出基于XML的数据安全交换系统,包括系统公共模块设计、数据发送方设计和数据接收方设计等;研究和提出了从数据发送到数据接收、保存和应用等整个交换过程中的需要各种安全措施,确保XML数据传输的绝对安全,并以.NET这一核心技术对交换系统中的关键部分应用进行实现。最后对本系统进行了总结,并提出了在今后一段的时间内,所需进一步研究的工作和方向。更多还原

【Abstract】 With the development of economic globalization, electronic data exchange has become more and more important as a part of the trade competition. However, both traditional EDI technique was more complicated and its cost was more expensive, it was harder to run into medium-sized and small-scale enterprise. According to advantages of cross-platform and more structured , XML solved previously difficult problem in data exchange. As a good format of data exchange, XML has been the first in data exchange. But, due to XML is a file of plain text and over-bulky, it affects safety and efficiency of transfer’s aspect during the transfer period. It’s worthy to be concerned. In current years, XML is coming on to apply in China. Under the different standards of data exchange, the system provides define principles in practice when data exchange is safety, convenient and efficient in an enterprise or among more enterprises.Firstly, we discussed the development of data exchange and analyzed security problem of XML. Secondly, we introduced XML language and discussed the basic principles of security of XML. The principles include that XML encryption and signature. Thirdly, via the relationship between XML and relevant database (RDB), we solved the conversion problem between XML and RDB. Fourthly, we designed a secure system of data exchange base on XML. The system includes public modules, sending modules and receiving modules. We researched and provided variously safety solutions for the whole date exchange process and insured XML transfer which is absolute security and taking .NET technique to achieve application in the key part of exchange system. Finally, the thesis summarized this system and indicated the research directions and problems during the future works.更多还原
