Information dissemination often takes theform of XML documents that are made available at Web servers, or that are actively broadcasted byWeb servers to interested clients. These documents often contain information at different degrees ofsensitivity, therefore a strong XML security platform and mechanism is needed. In this paper wedeveloped CIT/XML security platform and take a close look to syntax and processing of CIT/digitalsignature model, CIT/encryption model, CIT/smart card crypto and SPKI interface security models.Security services such as authentication, integrity and confidentiality to XML documents and non-XMLdocuments, which exchanged among various servers, are provided.展开更多

To get a big market on the Web, a special security infrastructure would need to be put into place transforming the wild-and-woolly Internet into a network with end-to-end protections. XML (extensible Markup Language) is widely accepted as powerful data representation standard for electronic documents, so a security mechanism for XML documents must be provided in the first place to secure electronic commerce over Internet. In this paper the authors design and implement a secure framework that provides XML signature function, XML Element-wise Encryption function, smart card based crypto API library and Public Key Infrastructure (PKI) security functions to achieve confidentiality, integrity, message authentication, and/or signer authentication services for XML documents and existing non-XML documents that are exchanged by Internet for E-commerce application.展开更多
