Task 4.1 Interoperability Across Wallets, Formats, and Protocols

Leads
Leif Johansson (leifj'at'sunet.se)
Marina Adomeit (marina'at'sunet.se)

Description
This task will create core interoperability specifications for the EWC ecosystem and applicability statements (including extensions) for each use case. We will reference existing standards and specifications, including the ARF where this is possible. The specifications will address both internal interoperability (how the various wallet implementations, including the European Reference Wallet, and the other infrastructure components support the use cases within EWC) and external interoperability (how the EWC ecosystem can support the use cases in other LSPs and interact with wallet- and PID-issuing solutions from all Member States), including addressing relevant gaps or issues.

Deliverables and Milestones

• D4.1 Core Interoperability Specification (Month 20)
  • Core interoperability specification on standards, protocols and extensions used in our project.
• D4.2 Applicability Statement for each use case (Month 22)
  • Document providing an applicability statement for the credentials for each use case, including any extensions.
• D4.3 Interoperability report on wallet implementation (Month 23)
  • Report on interoperability on all wallet implementations in our project (and the variations).
• MS13 Interoperability descriptions finalised (Month 23)
  • D4.1, D4.2 and D4.3 submitted, providing a full overview of interoperability specifications and applicability.

Task 4.2 Ecosystem Operation, Governance, Trust and Economics

Lead
Stef Haartman (Stephen.Haartman'at'gendigital.com)

Description
This task will make recommendations for the governance models for the digital travel credentials use case applications and all the scenarios involved. A governance framework describes the ecosystem of participants in the use case, how they work together within the ecosystem, and what the rules for the ecosystem are to be able to operate in their appropriate context. The pilot will explore the economics and possible business incentives of the ecosystem and trust framework.

This task is split into 2 subtasks:
4.2.1 Ecosystem Operation, Governance and Trust
4.2.2 Economics

Deliverables and Milestones

• D4.4 Recommendation for ecosystem governance & trust model (Month 12)
  • Document describing a governance framework for the specific ecosystem of the Travel Credentials Use Case.
• D4.5 Ecosystem Business Model (Month 22)
  • Document describing the ecosystem business model, flow of funds, monetary operations, settlement mechanisms.
• MS14 Recommendation for ecosystem governance & trust model and economics (Month 22)
  • D4.4 and D4.5 submitted.

Task 4.3 The (Q)EAA and Credential Lifecycle

Leads
Matteo Simone Mirabelli (matteosimone.mirabelli'at'infocert.it)
Andreas Abraham (andreas.abraham'at'validatedid.com)

Description
This task will implement the capability of (qualified) electronic attestation of attributes issuing. (Qualified) attestation issuing services will be made available through (qualified) trust service providers, based on authentic and non-authentic sources, including the needed mechanisms to support revocation, publication of EAA catalogue(s) and other required services. The standards for (Q)EAA issuing will be based on the reference wallet implementation and ARF and use specific extensions where needed to support the use case.

Deliverables and Milestones

• MS15 7 Operational services providing QEAA (Month 12)
  • Phase 2 test-reports submitted (interoperability/end2end-testing completed). Capabilities available to full- scale piloting.
• D4.6 At least 7 operational services providing QEAA for all wallets and supported standards in EWC (Month 18)
  • 7 (Q)TSPs offering (Q)EAA to all wallets and supported standards in our project.

Task 4.4 Trust Services - Signing and Seals

Leads
Viky Manaila (vmanaila'at'intesigroup.com)
Andreas Abraham (andreas.abraham'at'validatedid.com).

Description
This task will implement the capability of (qualified) signing a document using the EUDI Wallet. Digital signature services will be made available externally (remote digital signature) according to standard protocols (CSC, ETSI TS 119 432), leveraging on the basic capabilities of a wallet to exchange verifiable credentials. In connection to the organisational identity components in our use case, this task will also make available (qualified) sealing capabilities.

Deliverables and Milestones

• D4.8 Overview and rationale for chosen signing methods (Month 6)
  • Report containing an overview of the various methods available for signing and sealing, and the rationale for choosing one or more of them for our project.
• MS16 7 operational signing services providing QES (signing and sealing) (Month 12)
  • Phase 2 test-reports submitted (interoperability/end2end-testing completed). Capabilities available to full- scale piloting.
• D4.7 At least 7 operational signing services providing QES (signing and sealing) for all wallets and supported standards in EWC (Month 20)
  • 7 (Q)TSPs offering QES (signing and sealing) to all wallets and supported standards in our project.

Task 4.5 Cross Domain Pilots & Reusable Building Blocks

Leads
Esther Makaay (esther.makaay'at'signicat.com)
Lal Chandran (lal'at'igrant.io)

Description
We will set up a continuous environment for testing and demonstrating interoperability & security. This will contain shared infrastructure support and reusable building blocks, including open-source components.
This task is split into different focus areas:

• Connectivity / Interop Testing
• Piloting
• Shared DLT Infrastructure
• Tools and building blocks
• Trust lists
• Reference Wallet

Deliverables and Milestones

• D4.9 Roadmap on deployment, test environment and reusable components (Month 4)
  • First version of the deployment roadmap.
• MS17 Deployment roadmap (Month 4)
  • First version of D4.9 (the deployment roadmap) submitted
• D4.10 Shared network infrastructure available (Month 4)
  • A shared identity network infrastructure based on distributed ledger technology, required to anchor W3C DIDs, endpoints and other features to support organisational wallets.
• D4.11 Test environment supporting all scenarios across the Digital Travel Credentials Use Case (Month 18)
  • Test environment supporting all phases of deployment (a.o. interoperability testing, end-user piloting) for all use case scenarios in our project.
