    Hyperledger Indy Besu as a permissioned ledger in Selfsovereign Identity
    (Open Identity Summit 2024, 2024) Shcherbakov, Alexander
    Self-sovereign Identity (SSI) represents an approach to digital identity that prioritizes privacy and empowers individuals to maintain control over the information associated with their identity. This approach aligns with GDPR and similar regulations and is gaining adoption across various governments, non-profit organizations, and commercial entities worldwide. A foundational element in SSI is a Verifiable Data Registry (VDR), which serves as a trusted repository for registering and accessing public keys, schemas, identifiers, and other data. A natural choice for a VDR is a distributed ledger or blockchain. Among the most stable and popular frameworks for SSI is Hyperledger Indy. Indy includes a custom implementation of a public permissioned ledger as a VDR. The Indy community has been developing a new experimental approach for a VDR in Indy: a permissioned ledger based on Hyperledger Besu. In this paper, we are going to discuss the importance, benefits, and technical details of this initiative.

    Integration of Self-Sovereign Identity into Conventional Software using Established IAM Protocols: A Survey
    (Open Identity Summit 2022, 2022) Kuperberg, Michael; Klemens, Robin
    Self-Sovereign Identity (SSI) is an approach based on asymmetric cryptography and on decentralized, user-controlled exchange of signed assertions. Most SSI implementations are not based on hierarchic certification schemas, but rather on the peer-to-peer and distributed “web of trust” without root or intermediate CAs. As SSI is a nascent technology, the adoption of vendor-independent SSI standards into existing software landscapes is at an early stage. Conventional enterprise-grade IAM implementations and cloud-based Identity Providers rely on widely established pre-SSI standards, and both will not be replaced by SSI offerings in the next few years. The contribution of this paper is an analysis of patterns and products to bridge unmodified pre-SSI applications and conventional IAM with SSI implementations. Our analysis covers 40+ SSI implementations and major authentication protocols such as OpenID Connect and LDAP.

    Self-Sovereign Identity als Grundlage für universell einsetzbare digitale Identitäten
    (HMD Praxis der Wirtschaftsinformatik: Vol. 58, No. 2, 2021) Ehrlich, Tobias; Richter, Daniel; Meisel, Michael; Anke, Jürgen
    In diesem Beitrag werden die Rolle digitaler Identitäten für eine funktionierende digitale Wirtschaft thematisiert und Anforderungen an das Management digitaler Identitäten abgeleitet. Bislang hat sich kein Ansatz für das Management digitaler Identitäten in der Breite etabliert, was zu einer Fragmentierung der ID-Landschaft sowie einer Vielzahl von Benutzerkonten für den Anwender führt. Mangels Standards ist zudem die Interoperabilität von digitalen Identitäten eingeschränkt. Dies führt zu einer Reihe von Problemen, die den effizienten und sicheren Umgang mit digitalen Identitäten behindern. Abhilfe verspricht das Konzept der Self-Sovereign Identities (SSI) und den damit verbundenen Standards „Verifiable Credentials“ und „Decentralized Identifiers“. Sie erlauben den flexiblen Austausch von manipulationssicheren digitalen Nachweisen zwischen Benutzern und Systemen und bilden damit die Grundlage für den Aufbau von Vertrauensbeziehungen im digitalen Raum. In diesem Beitrag werden das SSI-Paradigma vorgestellt und die Hürden diskutiert, die dem breitenwirksamen Einsatz dieses Konzepts entgegenstehen. Damit erhält der Leser einen kompakten Überblick verschiedener Ansätze für das Identitätsmanagement und die Potenziale selbst-souveräner Identitäten. Für die Gestaltung digitaler Dienste in Wirtschaft und Verwaltung sollte dieser Ansatz stärker berücksichtigt werden, um von den damit verbundenen Vorteilen zu profitieren. This paper addresses the role of digital identities for a functioning digital economy and outlines requirements for their management. So far, no approach for the management of digital identities has been widely established, which leads to a fragmentation of ID services as well as a variety of user accounts. Due to the lack of standards, the interoperability of digital identities is also limited. This leads to several problems that prevent the efficient and secure handling of digital identities. The concept of Self-Sovereign Identities (SSI) and the associated standards “Verifiable Credentials” and “Decentralized Identifiers” is a promising approach to improve the situation. They allow the flexible exchange of tamper-proof digital proofs between users and systems. Therefore, they form the foundation for building trust relationships in the digital space. This paper introduces the SSI paradigm and discusses the barriers that prevent the wide-scale adoption of this concept. With that, the reader gets a compact overview of different approaches for identity management and the potentials of self-sovereign identities. For the design of digital services in business and administration, this approach should be given greater attention to benefit from the associated advantages.
