Abstract: Digital signature is used to assure the data integrity, confidentiality and non-repudiation of the document being transmitted over the network. The combination of XML and digital signature is superior to traditional digital signature. This paper discusses a scheme of XML digital signature. This scheme is based on zero-knowledge proof, and is implemented by Java. It describes how to sign and verify a XML document with the digital signature scheme.
