XML undeniable signatures

Abstract

Extensible Markup Language (XML) has become an important universal language for the Internet-based business world. An XML document can be generated from various resources with varying security requirements. In order to ensure the integrity of the contents in the transactions, to maintain privacy and confidentiality, security is increasingly important. XML signatures are designed for the security of XML document transactions. They are involved with the authentication, data integrity and support for non-repudiation of the data they sign. They ensure that signatures cannot be verified without interaction with the signer. In this paper, we propose a new XML undeniable signature method that builds a bridge between the existing XML technologies and data security theories after discussing the existing XML digital signatures and RSA based undeniable signature technologies. We aim to provide a framework for the improvement of security technologies to improve XML applications.
