eSignature and eSeal validation workshop

The one-day workshop on "eSignature and eSeal validation" will discuss about standardization for eSignature/eSeal Validation services provided by Trust Service Providers, addressing conformity assessment, protocols and validation report. The objective is to define standards adequate to reach the objective of the eIDAS Regulation.


Since the entry into force of eIDAS (Regulation (EU) No 910/2014), there is a clear legal framework associated with the validation of eSignature and eSeal. The promotion of trusted validation services in particular, is seen as a key enabler for eSignature/eSeal in general as it provides a trusted, independent and neutral point of validation between the stakeholders of a signed transaction.

An EU-wide accepted scheme for conformity assessment is now needed for this kind of services. Without standardization effort, this may lead to implementations with non-equivalent levels of service and/or security that will not be adequate to reach the objective of eIDAS (Regulation (EU) No 910/2014), which is to support seamless cross-border experience for eSignature and eSeal of documents.

To promote recognition of services within the EU, ETSI started working on standardization of eSignature/eSeal validation, addressing policy and security requirements fitting within the EU scheme for supervision of (qualified) eSignature/eSeal validation services, as well as specifying the technical architecture, the protocol, and the validation report. The work intends to provide standards that will ensure coexistence of various solutions (e.g. protocols bindings).

The standards provided by ETSI aim at supporting not only eIDAS, but also other legal or regulatory frameworks.

The eSignature/eSeal validation workshop will:

  • Present basic fundamentals of the eSignature/eSeal validation landscape:
    • legal framework 
    • technical framework
  • Present the ETSI work as well as other initiatives on eSignature/eSeal validation as a trust service and on the eSignature/eSeal validation report
  • Validate that the ETSI work takes into account major existing solutions and standards without overlapping with other initiatives
    • Review how signature / seal validation service providers intend to deploy or have deployed their service and whether the approach taken by ETSI adequately supports it
    • Collect questions, answers and feedback from the audience on the ETSI work
