Specialist Task Force 426:
”Quick fixes to electronic signatures profiles - Phase 1b”

Who we are:

Team Leader: Konrad Lanz, Stiftung SIC (IAIK),
Team Members:
Andrea Caccia   Uninfo
Juan Carlos Cruellas Ibarz, UPC,
Julien Stern, Cryptolog International,

What we do:

In line with mandate M/460 this technical proposal covers Urgent Quick fixes - to be performed very rapidly leading to a quick and easy improvement of the functionality of the existing e-Signature standardisation deliverables, bringing them up to date with current practices.

The objective of this action is to specify a Baseline Profile (ETSI Technical Specifications) for all the Advanced Electronic Signatures, i.e. CAdES, XAdES, PAdES and ASiC (Associated Signatures), which corresponds to the minimum basic requirements in the context of the “Directive  2006/123/EC of the European Parliament and of the Council of 12 December 2006 on services in the internal market” (EU Services Directive henceforth), and provide the same basic features with minimal number of options or no options at all.

There will be two versions of the four deliverables CAdES, XAdES, PAdES and ASiC baseline-profiles, where the first versions will consider the short-term signature verification requirements only,  (please find ESI approved versions) and the second will contain the short-term and a long-term signature base-line profile.

The short-term requirements will be based on Commission Decision 2011/130/EU:”establishing minimum requirements for the cross-border processing of documents signed electronically by competent authorities under Directive 2006/123/EC of the European Parliament and of the Council on services in the internal market”. The long term requirements will be gathered during the work of this STF.

In the second phase the European Commission kindly hosts the Brussels workshop with the Services Directive Experts Group on the 14th of September 2011 14:00-18:00, that provides the assurance that the proposals for the long term AdES baseline-profiles meet the requirements and foster stakeholder engagement. Stakeholders were invited to provide position-papers, use-cases and requirements in the first half of July 2011 and received a formal invitation a moth ahead of the workshop. If needed a second workshop may be organized.

ETSI also established a stakeholders' mailing list to inform on the progress of M/460 execution, CEN/ETSI workshop, availability of specific drafts for comments and important milestones, if you would like to be added to this list please email to esisupport@ETSI.ORG (CC:

Why we do it:

We operate under the Electronic Signature Mandate M/460 requirement for a “rationalised European eSignature standardisation framework” and Domain 5 (Electronic Signatures) of the EC’s 2010 to 2013 ICT Standardisation Work Programme. It identifies the need for actions to be carried out urgently to establish a framework for electronic signature referred to as “phase 1b – ETSI quick fixes”.  The “quick fixes” work plan is primarily aimed at providing urgent quick technical fixes to existing electronic signatures standards, in line with the description of mandate M/460 first aims and with the result of the CROBIES study.

In implementing the Services Directive (Directive 2006/123/EC) the need has been identified for the use of Advanced Electronic Signatures (AdES) across Europe.  For this to be achieved consistently across Europe, a common profile needs to be established for the use of AdES by EU member states.

A joint ETSI / CEN programme for implementing mandate M/460 is described in the document “Joint CEN-ETSI response to mandate M/460”.

How we do it:

The four experts will be collectively involved in the scoping, requirements gathering and fulfilment mechanisms definition tasks. This will ensure that coherence is maintained across all of the developed ETSI TS.

 The STF will report on its activities at each TC ESI meeting (estimated to be 3 meetings over the duration of the action). TC ESI will then ensure that the CEN-ETSI eSign CG is informed on the progress of the work. When invited, the STF leader will occasionally attend the CEN-ETSI eSign CG meetings to report on specific issues..
