    Applying assurance levels when issuing and verifying credentials using Trust Frameworks
    (Open Identity Summit 2021, 2021) Martinez Jurado, Victor; Vila, Xavier; Kubach, Michael; Henderson Johnson Jeyakumar, Isaac; Solana, Albert; Marangoni, Matteo
    Technical interoperability of the issuance, presentation, and verification of verifiable credentials (VC) across domains of trust is a current challenge for self-sovereign identity. We present an approach incorporating different levels of assurance and trust domains in an eIDAS compliant way. This is illustrated through a use case with real-world relevance: the issuance and cross-border usage of the European Health Insurance Card.

    Combination of x509 and DID/VC for inheritance properties of trust in digital identities
    (Open Identity Summit 2022, 2022) Bastian, Paul; Stöcker, Carsten; Schwalm, Steffen
    The proposal for review of the eIDAS Regulation from 2021 has opened strong expectations for a deep change in traditional identity models. The user-centric identity model proposed starts with the creation of European Digital Identity Wallets that will enable citizens’ control over their data in identification and authentication processes without control by entities providing the identification services. Likewise digital identities and digital signatures are in place and interoperability between existing solutions mainly based on x509 certificates and decentralized PKI using DID/VC foreseeable. The paper provides various options to address different aspects in combining x509 and DID/VC approaches.

    A shared responsibility model to support cross border and cross organizational federation on top of decentralized and self-sovereign identity: Architecture and first PoC
    (Open Identity Summit 2023, 2023) Kubach, Michael; Henderson, Isaac; Bithin, Alangot; Dimitrakos, Theo; Vargas, Juan; Winterstetter, Matthias; Krontiris, Ioannis
    This paper discusses the challenges of transitioning from legacy federated identity systems to emerging decentralized identity technologies based on self-sovereign identities (SSI) and verifiable credentials, which are being used in initiatives such as Gaia-X and Catena-X for secure and sovereign data sharing. The adoption of SSI and decentralized identity technologies requires a standardized reference model that addresses challenges around trust in cross-border and crossorganizational federations based on decentralized identities. To facilitate this transition, the paper proposes a new Fed2SSI architecture that introduces a middle layer of abstraction for the policybased transformation of credentials, enabling interoperability between legacy federated identity solutions and SSI/decentralized identity environments. The architecture is implemented in a prototype and an exemplary use case is presented to illustrate the added value of this approach.
