EUDIReady Sovereign Trust Core

EUDIReady delivers deep architectural specifications for sovereign digital identity, EUDI Wallet Architecture & Reference Framework (ARF), Qualified Trust Service Providers (QTSP), and Zero-Knowledge selective disclosure.

EUDIReady System Architecture

Sovereign Trust Core: EUDI Wallet Relying Party Pipeline — OpenID4VP Verifiable Presentation Verification, Zero-Knowledge Selective Disclosure Ingress

Subsystems & Cryptographic Modules

OpenID4VP Relying Party Verifier Daemon
Digital Credentials Query Language (DCQL) Parser
Zero-Knowledge Selective Disclosure Validator

Architectural Layers & Ingress Bus

Layer 1: Hardware Cryptographic Enclave & Keystore (Common Criteria EAL6+ / eSE / TEE / FIPS 140-3 Level 4 / Hardware Root-of-Trust): Hardware key generation, tamper-resistant memory storage, and device-bound biometric attestation satisfying LoA High requirements.
Layer 2: Protocol Engine & Selective Disclosure (OpenID4VCI / OpenID4VP / SD-JWT-VC / BBS+ Pairing Cryptography / W3C VC 2.0): Manages high-throughput credential issuance, presentation exchange, and zero-knowledge selective attribute disclosure.
Layer 3: Qualified Trust Services & Legal Finality (ETSI EN 319 401/411/412 / QES / QSeal / Remote QSCD / RFC 3161 Time-Stamps): Provides legally binding electronic signatures and seals with cross-border mutual recognition under eIDAS Article 25.
Layer 4: Sovereign Trust Framework & Cross-Border Audit (EUTL / LOTL XMLDSig / StatusList2021 / ASiC-E Containers / Audit Logging): Dynamic supervisory trust chain validation, sub-millisecond revocation lookups, and tamper-evident forensic compliance.

Security Metrics & Latency Benchmarks: < 6.8 ms (Verification Latency) | CC EAL6+ (Hardware Enclave Level) | 14,500/s (Throughput Capacity) | Article 25 (Legal Admissibility)

European Digital Identity Framework & Cryptographic Trust Architecture in EUDIReady

The European Digital Identity Framework established under Regulation (EU) 2024/1183 (eIDAS 2.0) fundamentally restructures how citizens, businesses, and public administrations interact across national borders. Within EUDIReady, we formalize the cryptographic protocols, hardware security enclave boundaries, and decentralized attribute exchange flows required to deploy sovereign digital trust at scale. By unifying the EUDI Wallet Architecture and Reference Framework (ARF), Qualified Trust Service Providers (QTSP), and advanced zero-knowledge selective disclosure primitives, EUDIReady guarantees cross-border legal finality, strict user data minimization, and uncompromised privacy protection.

Core Trust Engineering Areas

EUDI Relying Party Reference Architecture using OpenID4VP and DCQL — Designing server-side verification pipelines capable of requesting minimal attribute sets and validating cryptographic presentation tokens in under 50ms.
Cross-Platform Interoperability Testing across European Pilot Wallets (POTENTIAL, DC4EU, NOBID, EWC) — Technical findings from large-scale pilots evaluating cross-border credential exchange between different national wallet implementations.
Anonymous Age Verification without Identity Disclosure in EUDI Wallets — Implementing non-interactive zero-knowledge range proofs allowing users to prove age $\ge 18$ without disclosing date of birth or full name.
