World Wide Web Consortium Issues XML Signature as a W3C Recommendation

15.02.2002


Joint work with IETF produces XML-based solution for digital signatures, foundation for Secure Web services



The World Wide Web Consortium (W3C) has issued XML-Signature Syntax and Processing (XML Signature) as a W3C Recommendation, representing cross-industry agreement on an XML-based language for digital signatures. A W3C Recommendation indicates that a specification is stable, contributes to Web interoperability, and has been reviewed by the W3C Membership, who favor its widespread
adoption.

"XML Signature is a critical foundation on top of which we will be able to built more secure Web services," explained Tim Berners-Lee, W3C Director. "By offering basic data integrity and authentication tools, XML Signature provides new power for applications that enable trusted transactions of all sorts."



Digital Signatures are Essential to Web Services

Digital signatures are created and verified using cryptography, the branch of applied mathematics concerned with transforming messages into seemingly unintelligible forms and then back again. Digital signatures are created by performing an operation on information such that others can confirm both the identity of the signer, and the fidelity of the information. This capability is important to a growing number of XML protocol, publishing and commerce applications.

XML Signature Combines Data Integrity with Extensibility

While there are technologies one can use to sign an XML file, XML Signature brings two additional benefits.

First, XML Signature can be implemented with and use many of the same toolkits one is using for XML applications.

Second, XML Signature can process XML as XML instead of a single large document. This means multiple users may apply signatures to sections of XML, not simply the whole document.

As more commercial applications are used to send XML documents through a series of intermediaries, the ability to sign sections of a document without invalidating other portions is invaluable, whether for invoices, orders, or applications.

One may independently sign an XML payload from the XML envelope that carries it for a short period. As a result, when you remove, add or change the protocol envelope the signature on the payload itself is still valid.

Similarly, XML Signature provides flexibility when a signed XML form is delivered to a user. If the signature were over the full XML form, any change by the user to the default form values would invalidate the original signature. XML Signature permits both the original form and user`s entries to be independently signed without invalidating the other.

And of course, while XML Signature is tailored to XML processing, it can be used to sign any data, such as a PNG image.

XML Signature Supports XML Encryption and Key Management

XML Signature serves as the foundation for other ongoing W3C work including XML Encryption, which provides a mechanism to secure parts of XML documents, and XML Key Management, which provides a simple protocol for lightweight XML applications to obtain the key necessary for signature and encryption.

IETF/W3C Brings Together Industry Experts; Public Review

The XML Signature Working Group is the first joint W3C/IETF Working Group, and is the first W3C technical Working Group to operate entirely as a public group. This provided independent developers with a clear window on the XML Signature work in all stages of development, and brought a wide range of implementation experience. XML Signature already enjoys significant support and deployment, as highlighted in the testimonials.

Participants in the joint IETF/W3C Working Group included representatives from organizations whose lead research and commercial work in the area of digital signatures and security, including Accelio, Baltimore, Capslock, Citigroup, Corsec, Georgia State University, IAIK TU Graz, IBM, Microsoft, Motorola, Pure Edge, Reuters Health, Signio, Sun Microsystems, University of Siegen, University of Waterloo, VeriSign Inc., and XMLsec.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
