XML Security Middleware

XML is coming to be the incontrovertible standard for E-commerce messaging and data exchange, and has become an efficient means for data exchange and data manipulation on Internet. On the Other hand, there is one great problem that obstacles E-commerce to be properly deployed, i. e. security of Internet E-commerce messaging and data exchange. If lacking of trust and reliability, those messages and data would have little use. At present, the most important sets of developing specifications in the area of XML-related security are XML encryption, XML signature, XACL, SAML, and XKMS. This thesis mainly probes into XML encryption.Under the situation of the high speed development in Internet, the middleware which based on distributed system has got substantially development and extensive application. Therefore, we set up this XML security system in the form of middlwware such as Web services.At present, encrypting a complete XML document, testing its integrity, and confirming the authenticity of its sender is a straightforward process. But it is increasingly necessary to use these functions on parts of documents. In our designed safe system, we can encrypt and decrypt, digital signature, authorization and authentication the any part in XML document. In this way, not only guarantee the relevant information of the electronic commerce at pass should in the middleware, can resistspffing identity, tampering with data, repudiation, information disclosure the etc. The system insure the news can use the sex, making it but even vivid, to adapt to the demand of the different and safe Class, better service and require with the different business enterprise and customer.
