AP2Cert Sovereign Trust Core

AP2Cert delivers deep architectural specifications for sovereign digital identity, EUDI Wallet Architecture & Reference Framework (ARF), Qualified Trust Service Providers (QTSP), and Zero-Knowledge selective disclosure.

AP2Cert System Architecture

Sovereign Trust Core: AP2 Trust Certification Authority — Qualified Trust Provider Attestation, Hardware Enclave Audits & ETSI 319 Compliance

Subsystems & Cryptographic Modules

ETSI EN 319 401 General Policy Auditor
ETSI EN 319 411-1 / 411-2 TSP Verifier
Common Criteria EAL4+ / EAL6+ Enclave Evaluator
Certificate Revocation List (CRL) Publisher
Automated CAB Forum & eIDAS Linter

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 AP2Cert

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 AP2Cert, 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, AP2Cert guarantees cross-border legal finality, strict user data minimization, and uncompromised privacy protection.

Core Trust Engineering Areas

ETSI EN 319 Audit Framework for Qualified Trust Service Providers — Step-by-step technical compliance requirements for ETSI EN 319 401, 411-1, and 411-2 certifying public key infrastructure for eIDAS 2.0.
Common Criteria CC EAL4+/EAL6+ Cryptographic Enclave Vulnerability Evaluations — Hardware security module (HSM) and secure element (SE) penetration testing, side-channel attack countermeasures, and fault injection defenses.
Automated X.509 Certificate Linting for Qualified Trust Services and QWACs — Real-time verification of RFC 5280, ETSI EN 319 412 extensions, and QCStatements to prevent misissuance and supervisory revocation.
