TPMVault: Selagem de Segredos Pós-Quântica, Anti-Rollback Monotônico e Políticas NVRAM

A TPMVault fornece armazenamento selado aplicado por hardware, liberação de segredos autorizada por políticas e motores de arquivamento de chaves pós-quânticas, ancorando segredos corporativos, chaves mestras de banco de dados e certificados privados diretamente em raízes de confiança de hardware FIPS 203/204.

TPMVault Hardware Sealed Storage & Policy Execution Pipeline

NVRAM access controller, policy authorization tree, and post-quantum unseal engine

Central System: TPM Vault Controller - Policy-Authorized NVRAM

Cryptographic Nodes

  • Secure NVRAM Array
  • Policy Tree Evaluator
  • PCR State Comparator
  • Decapsulation Unseal Core
  • Hardware Audit Logger

Architectural Layers & Protocols

  • Secure NVRAM Silicon Plane (Silicon-Oxide-Nitride-Oxide-Silicon (SONOS) Flash): Providing 256 KB of hardware-encrypted, wear-leveled non-volatile storage isolated from host OS.
  • Complex Authorization Policy Trees (TPM2_PolicyOR / TPM2_PolicyAuthorize): Enforcing multi-condition authorization logic: PCR match AND user biometric AND time-lock.
  • Post-Quantum Key Unwrapping (FIPS 203 ML-KEM Key Encapsulation Mechanism): Decrypting sealed enterprise secrets using hardware-bound private keys only when policies pass.
  • Tamper-Evident Access Auditing (Hardware Monotonic Counters & Audit Logs): Incrementing non-resettable counters on every unseal attempt to detect brute-force tampering.

Key Metrics: 256 KB (Hardware NVRAM Capacity) | < 12 ms (Policy Evaluation Time) | SONOS (Tamper-Resistant Storage) | Zero-Leak (Memory Remanence Defense)
