OASIS Digital Signature Services eXtended (DSS-X) Technical Committee

The original Call For Participation for this TC may be found at http://lists.oasis-open.org/archives/tc-announce/200706/msg00012.html

The charter for this TC is as follows.

Name of the TC

OASIS Digital Signature Services eXtended (DSS-X) Technical Committee

Statement of Purpose

This Technical Committee has as its mandate production of new profiles of the existing OASIS Digital Signature Services core protocol "Digital Signature Service Core Protocols, Elements, and Bindings Version 1.0" and maintenance of 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.

This further includes 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.

Scope of the Work

The scope of activity for this TC will be within the following topics:

  1. Support of the server-based creation and verification of different types of signatures, among which the most relevant ones are XML Sig and CMS, and timestamps, both RFC 3161 and the XML time-stamps defined by the OASIS Digital Signature Services (DSS) TC.
  2. Production of new profiles suitable for a number of environments and purposes, which spread the usage of the specifications.
  3. Production of an analysis of inter-relationship among existing profiles in a matrix where new profiles shall state their relationship to existing ones.
  4. Production of dissemination material for promoting usage and facilitating tools development.
  5. Maintenance of the existing OASIS DSS standard and core protocol "Digital Signature Service Core Protocols, Elements, and Bindings Version 1.0" and related profiles produced by the former OASIS Digital Signature Services Technical Committee, subject to appropriate access to underlying intellectual property.


Below follows the list of generic deliverables (estimated completion Q4 2008):

  1. New DSS Profiles
  2. Further Interoperability tests
  3. Cross Matrix for existing profiles showing their inter-relationship
  4. WSDL definition for the DSS soap bindings
  5. Maintenance of "Digital Signature Service Core Protocols, Elements,and Bindings Version 1.0"
  6. Maintenance of existing Profiles

Below follows the list of candidate new profiles:

  1. Visible signatures
  2. Profile for ebXML
  3. Profile for individual reports on every signature verified in multi-signature documents
  4. Profile for requesting signed verification responses
  5. "baseline" profiles. Profiles for basic functions in support of generation and verification of XML signatures, CMS signatures, XML time-stamps and RFC 3161 time-stamps.
  6. Handling of signature & service policy
  7. Profile for supporting centralized encryption and decryption services

This list must not be taken as a closed one: the TC may decide to specify any other additional suitable profile during its lifetime. Additionally the TC may decide to drop one of these candidates if there is not sufficient support.
