XML文档加密和签名的研究与实现

针对普通XML文档的机密性和完整性需求，首先介绍了XML文档加密与签名的原理和语法结构，然后研究了XML文档加密与签名的类型，在此基础上用java语言实现XML文档的加密和数字签名，最后提出了XML文档的安全交换模型。实验表明，该方法能够有效地确保XML文档的机密性和完整性，是实现XML文档安全交换的一种很有发展前景的保障技术。

The Research and Realization of XML Document Encryption and Signature

In order to solve the requirements of confidentiality and integrity of XML documents, this paper firstly introduces the principle and structure of XML encryption and digital signature, and then researches the type of XML encryption and digital signature. Next this paper takes advantages of the Java language to realize the encryption and digital signature of XML documents. Finally, the secure exchange model of XML document is presented. The experiment demonstrates that the encryption and signature method we proposed can ensure the confidentiality and integrity of XML documents and it is a promising security technique for XML document transitions as well.
