XML Digital Signature And Application In Electronic Commerce

XML digital signature combines the safety and flexibility, breaks the limitation of traditional digital signature to the EC. XML digital signature not only guarantees the integrity, the authenticity and the undeniable of the information, but also improves the expansibility and interactive of the data. The development of XML digital signature has safeguarded the EC's security and reliability, also increased its flexibility and validity.At present XML technology in most EC platform only used for information promulgated. The reliable transaction process has not been implemented. XML digital signature can greatly improve the essential characteristic of EC transaction. It causes the information exchange of EC between different systems in Internet to be possibly carried on. Therefore using the XML digital signature technology effectively is especially important for developing the modern electronic commerce.The paper introduces the basic algorithms in cryptology of XML digital signature technology first, and summarizes the XML and Java technology related to in the article. With the basic principle of XML digital signature, designs the digital signature project which can be used for the independent XML data. Then carry on the application process of digital signature for the general XML documents with the JAVA language. In the paper also thoroughly discuss the present situation, the characteristic and the future of the XML digital signature in EC. Finally summarize the restriction factors of XML digital signature, and find the direction of further study.
