TPMVault: 양자 내성 기밀 봉인, 단조 카운터 기반 롤백 차단 및 NVRAM 접근 제어

TPMVault는 엔터프라이즈 기밀, 데이터베이스 마스터 키 및 프라이빗 인증서를 FIPS 203/204 하드웨어 신뢰 루트에 직접 고정하는 하드웨어 강제 밀봉 저장소, 정책 승인 기반 시크릿 해제 및 양자 내성 키 보관 엔진을 제공합니다.

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)
