The charter for this TC is as follows.


OASIS Digital Signature Services Technical Committee (DSS)

Statement of Purpose

The Digital Signature Services Technical Committee has as its mandate the development of techniques to support the processing of digital signatures. This mandate includes defining an interface for requesting that a web service produce and/or verify a digital signature on a given piece of data and techniques for proving that a signature was created within its key validity period.

The TC will develop a protocol for a digital signature creation web service. Providing digital signatures via such a web service facilitates policy-based control of the provision of the signatures.

The TC will develop a protocol for a digital signature verification web service that can verify signatures in relation to a given policy set.

The TC will develop an XML-based protocol to produce cryptographic time-stamps that can be used for determining whether or not a signature was created within the associated key's validity period or before revocation. The TC will also develop an XML format for cryptographic time-stamps.

Finally, the TC will develop a set of profiles of the aforementioned protocols. These profiles will define specific uses of the general protocols to address specific applications.

List of Deliverables

The new TC will have the following deliverables:

  1. an XML-based protocol for signature and time-stamp creation and verification.
  2. bindings for the protocol elements in 1 including SOAP and HTTP and TLS security.
  3. a set of profiles for the application of the above protocols to specific application areas.
