    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.

    Qualified Electronic Signatures with the EU Digital Identity Wallet
    (Open Identity Summit 2024, 2024) Wich, Tobias; Hühnlein, Detlef; Otto, Florian; Prechtl, Mike
    Art. 5a of the amended eIDAS-Regulation (EU) 2024/1183 establishes the European Digital Identity Framework and introduces the European Digitial Identity Wallet (EUDIW), which will meet the requirements of assurance level “high” for identity proofing and authentication (see Art. 5a Nr. 11) and is envisioned to be able to create Qualified Electronic Signatures (QES) free of charge for non-professional purposes (see Art. 5a Nr. 4 (e) and Nr. 5 (g)). As it will not be feasible in practice to certify the secure elements of all smartphones in the market as Qualified Signature Creation Device (QSCD), one needs to look at remote signature solutions along the lines of ETSI TS 119 432 and the specification developed within the Cloud Signature Consortium (CSC) . The Architecture and Reference Framework (ARF) makes it clear that the EUDIW will support Verifiable Credentials (VCs) for the purpose of strong identification and authentication and the only missing step to enable QES in the EUDIW seems to be the integration of Verifiable Credentials and Verifiable Presentations according to W3C with the remote signature protocol of the CSC-API. The present paper shows how to integrate the two worlds to enable QES in the EUDIW using emerging standards, such as Selective Disclosure JSON Web Tokens (SD-JWT) and OpenID for Verifiable Presentations (OID4VP).
