AP2Safe Sovereign Trust Core

AP2Safe delivers deep architectural specifications for sovereign digital identity, EUDI Wallet Architecture & Reference Framework (ARF), Qualified Trust Service Providers (QTSP), and Zero-Knowledge selective disclosure.

AP2Safe System Architecture

Sovereign Trust Core: Hardware Secure Element Enclave — FIPS 140-3 Level 4 Key Vaults, Zero-Leakage Side-Channel Defense & Memory Shielding

Subsystems & Cryptographic Modules

Hardware Cryptographic Enclave (ARM TrustZone / Intel SGX)
Tamper-Resistant Physical Memory Encryption (TME)
Zero-Leakage Constant-Time Math Accelerator
Remote Hardware Attestation Verifier
Physical PUF (Physically Unclonable Function) Anchor

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 AP2Safe

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 AP2Safe, 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, AP2Safe guarantees cross-border legal finality, strict user data minimization, and uncompromised privacy protection.

Core Trust Engineering Areas

Hardware Security Modules: FIPS 140-3 Level 4 Physical and Logical Protection — Physical intrusion detection mesh, active zeroization circuits, and cryptographic boundary defense against advanced laboratory extraction.
Confidential Computing Enclaves for Privacy-Preserving Identity Proofing — Isolating raw identity attribute verification within encrypted memory enclaves (Intel TDX, AMD SEV-SNP, ARM CCA) with verifiable remote attestation.
Physically Unclonable Functions (PUF) for Unclonable EUDI Device Binding — Deriving hardware-bound private master seeds from silicon manufacturing microscopic variations without storing secrets in non-volatile flash.
