SLHDSACert: FIPS 205 认证标准、极度保守的最高密码安全底座与 SPHINCS+ 工业落地

SLHDSACert 专注于 NIST FIPS 205 无状态基于哈希的数字签名算法（SLH-DSA，前身为 SPHINCS+），构建具备 50 年超长生命周期的根证书颁发机构 (Root CA)、固件安全签名飞地以及完全不依赖格数学计算困难性假设的抗量子信任锚点。

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)
