EIDASSafe Sovereign Trust Core

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

EIDASSafe System Architecture

Sovereign Trust Core: Sovereign Identity Vault & Enclave — FIPS 203 ML-KEM Post-Quantum Key Encapsulation, EAL6+ Secure Storage & Privacy Vaults

Subsystems & Cryptographic Modules

Post-Quantum ML-KEM Key Encapsulation Vault
Encrypted Identity Attribute Safe (AES-256-GCM)
Zero-Knowledge Blind Attestation Engine
Multi-Party Computation (MPC) Key Shard Custody
Emergency Key Recovery & Social Guardian Protocol

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 EIDASSafe

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

Core Trust Engineering Areas

Post-Quantum Cryptography for Long-Term Sovereign Identity Vaults — Deploying FIPS 203 (ML-KEM) and FIPS 204 (ML-DSA) to protect sensitive citizen biometrics and credentials against 'Harvest Now, Decrypt Later' attacks.
Threshold Cryptography and Multi-Party Computation (MPC) for Wallet Key Custody — Splitting user private keys into 2-of-3 threshold shards distributed across device secure enclave, cloud HSM, and recovery guardians.
Blind Storage and Oblivious RAM for Zero-Knowledge Identity Enclaves — Preventing access pattern leakage and memory side-channel extraction during high-throughput credential storage and querying.
