New Digital Signature Services (DSS) OASIS Standard Assures Authenticity of Data for Web Services

Boston, MA, USA; 7 June 2007 -- OASIS, the international standards consortium, today announced that its members have approved Digital Signature Services (DSS) version 1.0 as an OASIS Standard, a status that signifies the highest level of ratification. DSS defines an XML interface to process digital signatures for Web services and other applications, enabling the sharing of digital signature creation, verification and other associated services, without complex client software and configuration.

"DSS makes it easy to use digital signatures because it lets companies control their signature applications on an organizational basis through a network-based server," said Juan Cruellas of Centre d'aplicacions avanades d'Internet (CANET), co-chair of the OASIS DSS Technical Committee. "Instead of being managed individually, signing keys are maintained on a secure server with controls that minimize the risk of compromise. Signatures can still be created by authorized individuals, but instead of requiring specialized signing equipment for each person, DSS allows organizations to use their existing authentication mechanisms, such as passwords, two factors, biometrics, etc."

DSS describes two XML-based request/response protocols, one for signatures and a second for verification. Using these protocols, a client can send documents to a server and receive back a signature on the documents; or send documents and a signature to a server and receive back an answer on whether the signature verifies the documents.

"A DSS signature secures an organization's documents efficiently and effectively while maintaining accountability down to the individual level," said Nick Pope of Thales eSecurity Ltd., co-chair of the OASIS DSS Technical Committee. "What's more, DSS allows sensitive signing keys to be protected by using tamper-proof signing devices and by locating the server in a room with controlled access. Costs are reduced with DSS, because security can be highly localized."

DSS supports a range of signature formats including XML and CMS. It is designed around a core set of elements and procedures which can be profiled to support specific uses such as time-stamping (including XML structured time-stamps), corporate entity seals, electronic post marks and code signing.

The OASIS DSS Technical Committee worked closely with the Universal Postal Union, an agency of the United Nations, to facilitate the use of DSS within its Electronic Post Mark system (UPU EPM).

"Deploying support for digital signatures can be extremely challenging, especially for large companies. The task of allocating and certifying user keys can be burdensome and difficult to secure," said OASIS president and CEO, Patrick Gannon. "The DSS OASIS Standard presents an approach to digital signing which significantly reduces these obstacles. The added services enabled by this standard are meeting global needs, and the Universal Postal Union is a good example."

The DSS OASIS Standard was developed by representatives of the American Bar Association, Austria Federal Chancellery, BEA Systems, CATCert-Agencia Catalana de Certificacio, IBM, Nokia, Universal Postal Union, and others. The DSS OASIS Standard and the archives of the OASIS DSS Technical Committee work are publicly accessible. OASIS hosts the dss-dev mailing list for exchanging information on implementing the standard.
