Central System: Custody Engine - Threshold FHE Core

Cryptographic Nodes

  • Threshold MPC
  • Encrypted Sign
  • Policy Quorum
  • Geodetic HSMs
  • Audit Chain

Architectural Layers & Protocols

  • Threshold Fully Homomorphic Secret Sharing (Distributed Ring-LWE Key Generation Protocols): Partitioning the master secret key into homomorphic shares distributed across geographic jurisdictions
  • Homomorphic Signature Generation (Multi-Party Threshold Signing without Key Assembly): Nodes collectively evaluate FIPS 204 ML-DSA or Schnorr signatures over homomorphically encrypted shares
  • Proactive Secret Resharing & Refresh (Automated Share Rotation without Changing Master Public Key): Periodically refreshing secret shares to neutralize slow-moving mobile adversaries and insider leaks
  • Governance, Policy Enclaves & Hardware Isolation (Geographically Distributed Hardware Security Modules (HSMs)): Enforcing organizational compliance policies (transfer limits, multi-officer biometrics) in hardware enclaves

Key Metrics: Zero-Key (Key Reconstruction in Memory) | M-of-N (Distributed Quorum Policy) | FIPS 140-3 (HSM Boundary Protection) | Instant (Proactive Key Resharing)

마스터 개인키를 단일 위치에서 절대 조합하지 않기

Traditional cold storage and multi-sig wallets suffer from physical recovery risks and quantum signature compromise. Threshold FHE enables signers to collectively generate valid post-quantum authorizations without ever reconstructing the private key in memory.
