    A Mechanism for Discovery and Verification of Trust Scheme Memberships: The Lightest Reference Architecture
    (Open Identity Summit 2017, 2017) Roßnagel, Heiko
    Electronic transactions are an integral component of private and business life. For this purpose, a certification of trustworthy electronic identities supported from authorities is often required. Within the EU-funded LIGHTest project, a global trust infrastructure based on DNS is built, where arbitrary authorities can publish their trust information. A high level description of the LIGHTest reference architecture is presented. Then, the Trust Scheme Publication Authority, which enables discovery and verification of trust scheme memberships is introduced.

    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.

    Unified Data Model for Tuple-Based Trust Scheme Publication
    (Open Identity Summit 2019, 2019) Wagner, Sven; Kurowski, Sebastian; Roßnagel, Heiko
    Trust schemes are widely used by authorities to support verifiers of electronic transactions to determine the trustworthiness of relying parties. With a tuple-based publication, in addition to the trust scheme membership, the requirements of the trust scheme are published. For this, the development and publication of a unified data model derived from existing trust schemes (e.g. eIDAS) is needed, where each requirement is explicitly represented by one tuple. The consolidation and development of this data model, which is based on nine existing trust schemes, is presented along with possible applications and added value (e.g. improved mapping of trust schemes) in the field of trust verification. The data model includes the three abstract concepts Credential, Identity, and Attributes and in total 98 concepts, which can be added to standard trust lists using ETSI TS 119 612.
