    Establishing Trust in SSI Verifiers
    (Open Identity Summit 2023, 2023) Chadwick, David W.; Kubach, Michael; Sette, Ioram; Johnson Jeyakumar, Isaac Henderson
    We present a conceptual model that enables a user/holder with a wallet holding W3C Verifiable Credentials (VCs) to determine if the verifier is trusted to conform to GDPR so that it might be given the user’s personal identifying information contained in their VCs. We describe the implementation of this model using the TRAIN trust infrastructure and how wallets might interoperate with verifiers using different trust infrastructures. This leverages the OIDC GAIN proof of concept network currently being built using the draft OIDC Federation specification. We briefly describe the experiments that we have undertaken to date and the research that is still outstanding

    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.
