  • Security Notice: CVE-2020-13101 - The DSS core 1.0 became OASIS standard in 2007. It defines an interface for signature creation and validation for different signature formats and supports multiple variants to transport the documents to be signed or verified. The combination of InlineXML-option (XML-payload within the DSS transport document) and a specially crafted XMLDSig allows an attacker to circumvent the non-repudiation property of the signature. The details regarding this problem are explained in detail in a short (presentation). The recommended mitigation is to move to DSS-X core 2.0. Alternatively, deny the use of the InlineXML option.

  • Digital Signature Service Core Protocols, Elements, and Bindings v2.0 and Digital Signature Service Metadata v1.0 are approved as Committee Specification 02. See the announcement for details.

  • Digital Signature Service Core Protocols, Elements, and Bindings v2.0 Committee Specification Public Review Draft 03 (CSPRD03) and Digital Signature Service Metadata v1.0 CSPRD02 are for public review and comment through October 21st. See the announcement for details.


Overview

The DSS-X TC is developing new profiles of the existing OASIS Digital Signature Services core protocol "Digital Signature Service Core Protocols, Elements, and Bindings Version 1.0" and is maintaining this specification and its existing profiles. If at a later date it becomes clear that a new version of DSS is necessary then this may be produced by the TC.

DSS-X is also working on promotion of the standard and the creation of material helping dissemination. In general terms, the TC has the goal to facilitate the processing of digital signatures and time stamps in a client server environment.

The DSS-X TC is a member of the IDtrust Member Section.

Interoperability Testing

The OASIS DSS TC carried out a set of interoperability tests for assessing the worthiness of the specifications being developed, and the feasibility of easily getting interoperable implementations from them. A document has been produced that defines and describes a number of relevant test cases for the specifications. Its contents may benefit implementors of the DSS specifications.

Latest version of the aforementioned document may be found at:

http://www.oasis-open.org/committees/download.php/20508/oasis-dss-1.0-interop-wd-07.doc.

Members of the DSS TC, which have developed independent implementations of the specifications, have successfully participated in these interoperability tests.
