基于XSLT的XML元素级加密技术及其应用

Technology of XML element-wise encryption based on XSLT and its application

XML元素级加密是指对XML文档中的某一特定部分进行加密。在讨论基于XSLT的元素级加密技术的基础之上,提出了使用扩展函数来实现XML元素级加密 /解密的功能,并通过具体的例子来说明其可行性。相对于其他元素级加密技术,该方法最大的优点就是避免了部署与维护的麻烦,它把所有的安全操作都限制在了样式表内,而不涉及XSLT处理器,具有高可用性。

XML element-wise encryption is used to encrypt a certain part of XML document. In this paper, auther discussed the technology of element-wise encryption based on XSLT, and introduced a method that extension functions were used to provide function of encryption and decryption with some examples. Compared with other element-wise encryption technologies, the biggest advantage of this one is to avoid deployment and maintenance. All the security operations are confined to stylesheet and not involved in XSLT processor. So this technology has high-usability.
