AP2API 主权数字信任核心系统

AP2API 确立了针对 AP2 Trust Protocols, Decentralized Authentication APIs & Cross-Border Identity Interop 的企业级系统架构规范。覆盖欧盟第2024/1183号条例、EUDI钱包参考架构(ARF)、合格信任服务提供商(QTSP)、合格电子签名(QES)及基于SD-JWT/BBS+的零知识选择性披露。

AP2API System Architecture

Sovereign Trust Core: AP2 Trust Protocol API Gateway — OpenID4VCI & OpenID4VP High-Throughput REST/gRPC Identity Pipeline

Subsystems & Cryptographic Modules

OpenID4VCI Credential Issuance Endpoint
OpenID4VP Verifier Presentation Pipeline
Mutual TLS (mTLS) RFC 8705 Gateway
OAuth 2.0 Rich Authorization Requests (RAR)
Distributed Rate Limiter & Token Introspector

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 AP2API

AP2API formalizes the engineering specifications for ap2 trust protocols, decentralized authentication apis & cross-border identity interop, combining rigorous cryptographic protocols, hardware security enclaves, and sovereign legal trust architectures.

Core Trust Engineering Areas

OpenID4VCI Protocol Implementation: High-Throughput Credential Issuance Pipelines — Architectural specifications for credential endpoints, token bindings, pre-authorized code flows, and DPoP (RFC 9449) proof-of-possession tokens.
OpenID4VP Presentation Protocols: Real-Time Cross-Border Identity Verification — Implementing direct post presentation responses, DCQL query language parsing, and mdoc/SD-JWT multi-format presentation validation.
Zero-Trust API Gateway Architecture with mTLS and eIDAS Certificate Validation — Binding client X.509 qualified website authentication certificates (QWAC) to API sessions with sub-millisecond OCSP stapling verification.
