The XML Signature Working Group — a joint technical committee of the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C) — aims at enabling digital signing of documents using XML syntax. This capability is critical for a variety of electronic commerce applications, including payment tools. Signatures can provide integrity, message authentication and/or authentication services for data of any type, whether located within the XML that includes the signature or located elsewhere. XML signatures are generated by a hash function from the collection of references to the objects being signed; its syntax associates the content of resources with a key via a strong one-way transformation. This paper will provide further information on this and the proposed XML encryption standard.
