Abstract

This master’s thesis examines the European Digital Identity Wallet (EUDI Wallet) as a critical pillar of the European digital identity framework within the context of eIDAS 2.0 and investigates how it can support secure and interoperable electronic identification in cross-border scenarios. The theoretical part presents the core concepts of digital identification and digital credentials, the roles of the ecosystem (Issuer–Holder/Wallet–Verifier), and the modes of interaction in remote and proximity scenarios, with reference to standards such as OpenID4VP and ISO/IEC 18013-5 (mdoc/mDL). A central point of reference is the EUDI Wallet Architecture and Reference Framework (ARF), as it functions as the main technical “roadmap” that consolidates specifications, architectural principles, and requirements for interoperability, security, and privacy protection within the wallet ecosystem. To bridge theory and practice, an educational prototype web application is developed in Python/Flask, which simulates the roles of Issuer, Wallet, Verifier, and a “Mock Certificates” subsystem. The credentials are implemented as JWTs, state is managed with sessions (without a database), and the Verifier validates the signature and temporal validity, clearly presenting the validation outcome. Finally, limitations are documented and extensions are proposed, such as asymmetric cryptography, closer alignment with OpenID4VCI/OpenID4VP, selective disclosure, and revocation/compliance mechanisms. The overall approach is based on targeted bibliographic and technical research, so that the design choices of the prototype align with contemporary directions of the European digital identity ecosystem.
