基于RSA的XML不可否认签名方法研究*

针对普通XML数字签名的可否认问题，首先介绍了XML数字签名原理，然后分析了RSA签名机制和不可否认签名方案，在此基础上提出了一种改进的不可否认签名算法，并将其应用到XML数字签名结构的签名方法中，从而提出了一种新的XML不可否认签名方法。实验表明，该方法能够确保XML数字签名的不可否认性，是实现XML文档安全交换的一种很有发展前景的保障技术。

Research of RSA-based XML undeniable signature method

The paper aimed at the deniable problem of common XML digital signature, introduced the fundamental XML digital signature, and then analyzed the RSA digital signature mechanisms and the undeniable signature scheme. On the basis of the above,proposed an improved undeniable signature algorithm,and applied for signature method in the XML signature structure, so presented a novel XML digital signature method.The experiments demonstrate that the new XML deniable signature method can ensure that the non-repudiation of XML digital signature and it is a promising security technique for XML document transitions as well.
