The Research Of XML Data's Encryption Technology

XML (extensible Markup Language) is a kind of data standard set down by W3C (the World Wide Web Consortium). It is widely used in various fields because of it is traits, like structured, flexible, extensible and exchangeable. It is becoming to be the most important data-exchange technology in the enterprise or between enterprises. The generally used of XML increase the XML's security problem, such as integrated, confidential and nonrepudiation.Comparing with the traditional data type, XML has it is own feature. It will be very dangerous for the confidential informations and sensitive informations if the XML's Security is ignored. So, how to carry out the XML data's secure transmission is a very important problem.This paper is pointing on the XML-Security problems, and a scheme was designed for the XML's secure transmission which is being used in a application system, by researching the XML encryption and XML signature. This scheme provided a protection for the XML, which also can enhance the security of the data.The scheme is based on the .NET technology and presents a way to realize the security of XML data in logistic information by C# and satisfies the demand of XML data secures transmission.The scheme not only realized encrypting the XML's important element by thin pieces, and also brings forward a new encryption scheme: encrypt the data elements different times bases on the data elements' different security level, the higher the security level is, the more times is been encrypted, in order to ensure the important data's advanced security. This new scheme has some disadvantages, but the author expects that it can be a propeller for the development of the XML's secure encryption technology.
