    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 lightweight trust management infrastructure for self-sovereign identity
    (Open Identity Summit 2021, 2021) Kubach, Michael; Roßnagel, Heiko
    Decentralized approaches towards digital identity management, often summarized under the currently popular term Self-sovereign identity (SSI) are being associated with high hopes for a bright future of identity management (IdM). Numerous private, open source as well as publicly funded research initiatives pursue this approach with the aim to finally bring universally usable, trustworthy, interoperable, secure, and privacy friendly digital identities for everyone and all use cases. However, a major challenge that so far has been only rudimentary addressed, is the trust management in these decentralized identity ecosystems. This paper first elaborates this problem before presenting an approach for a trust management infrastructure in SSI ecosystems that is based on already completed work for trust management in digital transactions.

    A novel approach to establish trust in verifiable credential issuers in Self-sovereign identity ecosystems using TRAIN
    (Open Identity Summit 2022, 2022) Johnson Jeyakumar, Isaac H.; Chadwick, David W.; Kubach, Michael
    Self-sovereign identity (SSI) promises to bring decentralized privacy friendly identity management (IdM) ecosystems to everyone. Yet, trust management in SSI remains challenging. In particular, it lacks a holistic approach that combines trust and governance frameworks. A practical and scalable mechanism is needed for verifiers to externally verify their trust in credential issuers. This paper illustrates how TRAIN (Trust mAnagement INfrastructure), an approach based on established components like ETSI trust lists and the Domain Name System (DNS), can be used as a trust registry component to provide a holistic approach for trust management in SSI ecosystems. TRAIN facilitates individual trust decisions through the discovery of trust lists in SSI ecosystems, along with published credential schemas, so that verifiers can perform informed trust decisions about issued credentials.

    On the Market for Self-Sovereign Identity: Structure and Stakeholders
    (Open Identity Summit 2021, 2021) Kubach, Michael; Sellung, Rachelle
    For SSI solutions to make a significant impact, they need to be designed to cater to the requirements of the market to be adopted. Therefore, this paper proposes a structure of the market for SSI solutions, analyses its stakeholders, and surveys its current state.

    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.
