SLHDSACert: Certification FIPS 205, Fondations de Sécurité Conservatrices et Validation SPHINCS+

SLHDSACert est spécialisé dans les signatures numériques sans état basées sur le hachage du NIST FIPS 205 (SLH-DSA, ex SPHINCS+), concevant des autorités de certification racines garanties 50 ans, des enclaves de signature de micrologiciel et des ancres de confiance sans dépendance mathématique aux réseaux euclidiens.

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)
