Abstract:

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.
