MLKEMKey Entropy Harvesting & Dual-Seed Key Derivation Architecture

Quantum RNG ingestion, SP 800-90B health tests, and constant-time (d, z) expansion

Central System: Key Derivation Core - Dual-Seed (d, z) Generator

Cryptographic Nodes

  • Quantum Noise Source
  • Entropy Health Monitor
  • Conditioning Component
  • Polynomial Expansion Unit
  • Stack Zeroization Circuit

Architectural Layers & Protocols

  • Physical Noise Harvesting Layer (Photonic Phase-Jitter / Avalanche Breakdown): Harvesting raw quantum physical entropy with min-entropy H_inf > 7.99 bits per byte.
  • Deterministic Random Bit Generator (HMAC-DRBG / CTR-DRBG / Hash-DRBG): Cryptographic expansion of conditioned seeds with 256-bit forward and backward secrecy.
  • FIPS 203 Dual-Seed Expansion (SHAKE-256 (d, z) Derivation): Transforming 32-byte seed d into public matrix seeds rho and noise seed sigma; seed z for rejection.
  • Key Lifecycle & Scrubbing Controller (Memory-Locked Pages (mlock) & Active Zeroization): Ensuring private keys and intermediate seeds are immediately scrubbed upon completion.

Key Metrics: 256 bits (Entropy Seed Length) | < 45 µs (Keygen Cycle Time) | H_inf > 7.99 (Min-Entropy Guarantee) | Instant (Stack Zeroization)
