Technical Committee (TC) Electronic Signatures and Infrastructures (ESI) Activity Report 2019
Chair: Riccardo Genghini, Studio Notarile Genghini, eWitness SA
Responsible for the standardization of electronic signatures and related trust infrastructures.
The primary responsibility of our Electronic Signatures and Infrastructures committee (TC ESI) is to develop generic standards, guides and reports relating to electronic signatures and related trust infrastructures to protect electronic transactions and ensure trust and confidence with business partners.
TC ESI published several deliverables during 2019.
We updated our Technical Specification [TS 119 495] that defines Qualified Certificate Profiles and TSP Policy Requirements for Payment Services under the payment services Directive 2015/2366/EU (called PSD2).
Revisions were made to our Technical Specification [TS 119 102-2] on Procedures for Creation and Validation of AdES Digital Signatures (Part 2: Signature Validation Report).
A further Technical Specification was published [TS 119 511], defining policy and security requirements for trust service providers providing long-term preservation of digital signatures or general data using digital signature techniques.
We published TS 119 403-2 and TS 119 403-3, defining additional requirements for conformity assessment bodies assessing EU qualified trust service providers and auditing Trust Service Providers that issue Publicly-Trusted Certificates.
Remaining deliverables under the scope of STF 523 were published in February. These included two policy documents for Electronic Registered Delivery Providers and Registered Electronic Mail (REM) Providers, test specifications and a feasibility study on an interoperability profile between REM systems and UPU (Universal Postal Union) PReM-based systems [EN 319 521, EN 319 531, TS 119 524 Part 2, TS 119 534 Part 2 and TR 119 530].
The EC/EFTA-funded STF 560 worked on two topics. One considers two machine processable formats for signature policies [TS 119 172 Part 2 and TS 119 172 Part 3] that were published in December 2019. In the second, the STF made a study on the global acceptance of EU Trust Services. Supporting this, TC ESI hosted a series of four workshops in Dubai (May), Tokyo (May), Mexico City (June) and New York (September) as part of the ETSI study to investigate existing PKI-based trust services schemes operating in different regions of the world, and their possible mutual recognition/global acceptance. The study aims to identify further steps which could be taken to facilitate cross recognition between EU trust services, based on ETSI standards supporting the eIDAS Regulation and trust services from other schemes.
During 2019 interaction was maintained with a number of external bodies. In relation to deliverables on e-delivery, we worked with the European Commission / CEF (Connecting Europe Facility), CEN TC 331 WG2 (working on postal services) and UPU (Universal Postal Union).
We coordinated with OASIS DSS-X TC to ensure alignment and complementarity of specifications for remote signature creation and validation, building on the new OASIS DSS-X V2 specification that was published in July 2019.
Work progressed on protocols for remote signature creation, in alignment with the Cloud Signature Consortium’s (CSC) own work covering the JSON binding.
In cooperation with the European Banking Authority and Open Banking Europe, we adapted our Technical Specification [TS 119 495] for trust infrastructure to meet the needs of new payment services.
We shared information relevant to trust service providers with the Forum of European Supervisory Authorities.
We interacted with ISO TC 154 WG6, which is defining profiles of signatures formats building on the ESI formats.
We continued our liaison with the European cooperation for Accreditation, in particular for the maintenance of EN 319 403.
An MoU was established with ACAB'c, the Accredited Conformity Assessment Bodies' Council.
A new co-operation agreement was established with the Cloud Signature Consortium.
In January 2019 the TC ESI Vice Chair spoke – alongside the TC CYBER Chair and Vice Chair – at a second workshop in Brussels on the Cybersecurity Act and its link with standardization, jointly organized by ENISA, CEN, CENELEC and ETSI.
During October and November TC ESI conducted a remote Digital Signature Validation PlugtestsTM event.
