SLHDSACert：FIPS 205認証、保守的で堅牢なセキュリティ基盤、SPHINCS+適合性検証

SLHDSACertは、NIST FIPS 205ステートレスハッシュベース電子署名（SLH-DSA、旧SPHINCS+）に特化し、格子暗号の数学的仮定に依存しない50年耐用年数のルート認証局、ファームウェア署名エンクレーブ、耐量子信頼アンカーを設計します。

SLHDSACert Stateless Hash Tree Architecture & Hyper-Tree Topology

Hypertree hierarchy, FORS few-time signature engine, and WOTS+ one-time verification

Central System: FIPS 205 Root CA - Stateless Hypertree Engine

Cryptographic Nodes

  • FORS Few-Time Signer
  • WOTS+ One-Time Unit
  • Hypertree Merkle Mesh
  • SHAKE-256 / SHA-2 Harvester
  • Offline Root HSM

Architectural Layers & Protocols

  • Mathematical Foundation Plane (Second-Preimage Resistance of Cryptographic Hashes): Security rests entirely on standard hash properties (SHA-256 / SHAKE-256), independent of lattice mathematics.
  • Few-Time Signature Layer (FORS) (Forest of Random Subsets (FORS)): Signing message digests using multiple parallel trees, generating inputs for bottom-layer WOTS+ trees.
  • Multi-Layer Hypertree Architecture (Hierarchical Merkle Trees (d layers, h total height)): Amortizing key generation and signature sizing across a massive virtual tree of 2^64 leaf keys.
  • Stateless Operational Safety (Pseudo-Random Index Derivation from Message & Seed): Eliminating state-synchronization hazards: can sign unlimited messages without state corruption or key exhaustion.

Key Metrics: 50+ Years (Root CA Certificate Longevity) | Zero Lattice (Mathematical Assumption Independence) | Stateless (Operational Resilience) | FIPS 205 (NIST Standard Conformance)
