PQCCustody: Sharding MPC em Reticulados, Enclaves a Frio Air-Gapped e Governança Multi-Sig

A PQCCustody fornece custódia de ativos digitais de nível institucional, esquemas de assinatura em reticulados por limiar (t-ML-DSA), módulos de segurança de hardware (HSM) air-gapped e frameworks de governança em conformidade com SEC/FCA para proteger instituições financeiras, fundos soberanos e exchanges contra roubos financeiros quânticos.

PQCCustody Institutional Vault Architecture & Governance Topology

Multi-signatory quorum, air-gapped optical data diodes, and cold-storage HSM enclave

Central System: Institutional Vault Core - Threshold Lattice HSM Enclave

Cryptographic Nodes

  • Air-Gapped Cold HSM
  • Optical Data Diode
  • t-of-n Quorum Engine
  • Regulatory Policy Enforcer
  • Disaster Recovery Bunker

Architectural Layers & Protocols

  • Air-Gapped Physical Security Plane (Class-4 High-Security Underground Vaults): Housing cold-storage HSMs in electromagnetic Faraday cages isolated from the public internet.
  • Threshold Lattice Cryptography (Threshold ML-DSA-87 (t-of-n) Signing Protocol): Requiring multiple C-level executives and compliance officers to sign without assembling the master key.
  • Unidirectional Data Transfer (Hardware Optical Data Diodes & QR Air-Gaps): Transferring unsigned transactions into the air-gapped vault via light pulses, preventing incoming cyberattacks.
  • Governance & Regulatory Compliance (SOC 2 Type II / SEC Rule 17a-4 / MiCA Standard): Enforcing dual-authorization, withdrawal velocity limits, and automated tamper-evident audit trails.

Key Metrics: t-of-n (Threshold Governance Quorum) | FIPS 140-3 L4 (Physical Hardware Standard) | $0 Breach (Historical Asset Loss) | 100% Air-Gapped (Zero Internet Connectivity)

Custódia Pós-Quântica Institucional em Armazenamento Frio, Assinaturas Reticuladas com Limiar (t-ML-DSA) e HSMs Quânticos Air-Gapped

Referência técnica de engenharia autoritativa para institutional cold-storage post-quantum custody, threshold lattice signatures (t-ml-dsa) & air-gapped quantum hsms em normas NIST FIPS 203/204/205, criptografia em reticulados, mitigação de ataques por canal lateral e infraestrutura resistente a computadores quânticos.
