    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.

    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.
