PQCCustody: Gitterbasiertes MPC-Sharding, Air-Gapped Cold Enclaves & Multi-Sig-Governance

PQCCustody bietet institutionelle Verwahrung digitaler Vermögenswerte, gitterbasierte Schwellenwert-Signaturschemata (t-ML-DSA), luftspalt-isolierte Hardware-Sicherheitsmodule (HSM) und SEC/FCA-konforme Governance-Frameworks zum Schutz von Finanzinstituten und Staatsfonds vor quantenbasiertem Diebstahl.

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)
