Integrating Quantum-Resilient Trust Anchors into the European Digital Identity Wallet

Core engineering and protocols for eIDAS 2.0 EUDIW Wallet Architecture.

The Transformative Scope of EU Regulation 2024/1183 (eIDAS 2.0)

eIDAS 2.0 mandates that all 27 European Union Member States provide a standardized European Digital Identity Wallet (EUDIW) to every citizen by 2026. The wallet enables citizens to digitally verify their identity, access public services, open bank accounts, and sign contracts across borders. Crucially, eIDAS 2.0 mandates preparation for post-quantum cryptographic migration across all trust services.

Cryptographic Workflows in the EUDIW Architecture

EIDASVault provides the backend trust anchor for wallet credential issuance. When a government authority issues Person Identification Data (PID) or an educational institution issues a degree attestation, credentials are signed inside EN 419 221-5 compliant QSCD hardware using post-quantum digital signatures, ensuring cross-border legal validity across Europe.
