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 SourceDataReview

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 SourceDataReview, 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, SourceDataReview guarantees cross-border legal finality, strict user data minimization, and uncompromised privacy protection.

Core Trust Engineering Areas

High-Assurance Identity Proofing and Source Evidence Validation — Evaluating document authenticity, NFC chip cryptographic verification (ICAO 9303 Doc 9303), and passive authentication against ICAO PKD.
Authoritative Source Query Federation across European Base Registries — Unified data access layer connecting disparate civil registries, business registers, and vehicle administrations under strict GDPR compliance.
Synthetic Identity Detection and Biometric Injection Prevention — Advanced behavioral analytics, device fingerprinting, and digital document metadata forensics identifying manipulated onboarding evidence.
