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 SourceDataVerification

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

Core Trust Engineering Areas

Cryptographic Registry Attestation: Transforming Databases into Verifiable Sources — Generating sparse Merkle tree inclusion proofs allowing base registries to provide cryptographic proof of record state without exposing tables.
High-Performance REST and gRPC Verification APIs for National Registries — Architectural designs achieving sub-10ms query-and-sign latencies for continuous business register and identity validation.
Zero-Knowledge Database Membership Proofs for Private Attribute Verification — Proving a citizen is registered in a qualified taxpayer or voter roll without disclosing their unique national identification number.
