The quiet failure of "math-only" trust
Long-horizon data (5–100+ years) can outlive today's crypto.
Harvest-Now/Decrypt-Later makes archives captured today exploitable tomorrow.
Insider abuse and supply-chain compromise mean that—even when signatures verify—provenance can be manipulated at the source.
Purely algorithmic assurances aren't enough.
The consequence (why it matters now)
Auditors increasingly ask, "Can you still prove this exact artifact in 10–30 years?"
Meanwhile, HNDL risk means encrypted data exfiltrated now may be readable later.
When provers or signing keys are compromised, "valid" certificates can still represent untrue data—and long retention requirements amplify every vulnerability.
FieldHash solves this by adding physics-anchored evidence that complements cryptography
When you issue certificates, FieldHash captures quantum-execution fingerprints with device provenance and calibration context. Verification remains fast, local/offline, and policy-aware, backed by evidence that's impractical to reproduce without equivalent quantum hardware, parameters, and conditions. Simulation fallback is supported and clearly labeled as a lower-trust tier.
What FieldHash delivers
FieldHash:
“Quantum-Anchored Trust
for Mission-Critical Data”
-
Certificates can include device/backend IDs, job references, distribution digests and statistical fingerprints, and calibration snapshots—creating a time- and device-bounded fingerprint that's impractical to reproduce without equivalent hardware, parameters, and conditions.
-
Verifiers don't need quantum access. They validate the signed evidence package locally and apply versioned verification profiles (Strict / Standard / Offline-Optimized).
-
Evidence packages are signed with NIST-selected CRYSTALS-Dilithium (PQC). Private keys remain behind Vault/KMS/HSM boundaries with no application-memory egress. Optional Kyber KEM envelope is policy-gated.
-
Production enforces client mTLS plus short-lived JWT, fine-grained RBAC, intelligent rate limiting, and abuse protections. PII scrubbing protects logs and observability pipelines.
-
Supported optionally and off by default. Certificates remain fully offline-verifiable without it, preserving privacy while enabling additional auditability when needed.
How it works (at a glance)
Hash — Bind content with SHA-256 (primary) and SHA-512 (audit)
Execute — Run a parameterized circuit on IBM Quantum or Quantum Inspire (when configured), or simulation (clearly labeled)
Fingerprint — Derive a distribution digest and noise fingerprint; capture calibration snapshots
Sign — Seal the evidence with Dilithium under vault-only custody (optional Kyber envelope)
Verify — Anyone can verify locally; profiles enforce minimum shots, drift windows, and mode policy
Where it fits
Healthcare & Life Sciences
Clinical trial integrity and consent management for long‑term compliance.
- Why FieldHash: Quantum‑anchored certificates (when hardware is used), vault/KMS/HSM signing, offline verification, and PII‑aware observability.
- Deployments: Managed or on‑prem; air‑gapped simulation for enclaves; transparency optional and off by default.
Finance & Public Sector
Long‑horizon records that must outlast multiple crypto generations while meeting evolving audits.
- Why FieldHash: Physics‑anchored evidence + PQ signatures; local/offline verification; posture flags for auditors (mTLS/JWT/Vault).
- Deployments: Multi‑region, on‑prem, or hybrid; ETag/304 for efficient evidence distribution; optional transparency where required.
Legal & Compliance
Evidence packages that withstand courtroom scrutiny with offline verification and clear trust tiers.
- Why FieldHash: Signed evidence (distribution digest, noise fingerprint, calibration snapshots when hardware is used) plus deterministic profiles.
- Deployments: Enterprise or air‑gapped verification; package formats compatible with review workflows.
Defense & Critical Infrastructure
Strict profiles; on‑prem/air‑gapped deployments when quantum access is restricted.
- Why FieldHash: Hardware‑backed evidence for high‑assurance profiles, simulation fallback clearly labeled for development/training.
- Deployments: IL/Fed environments, enclave installs; evidence distribution via controlled channels; posture flags for operations.
AI & Content Provenance
- Prove synthetic content authenticity with quantum‑anchored evidence. Bind an artifact’s digest to a hardware‑measured fingerprint plus device provenance and calibration context.
- Minimal metadata, maximum privacy: use digests (prompt/parameters), model/process IDs, and timestamps. Optional C2PA assertion; COSE/CBOR or VC packaging.
What's live in v2.1.x
Quantum backends: IBM Quantum & Quantum Inspire; simulation fallback clearly labeled; policy-driven failover
APIs (v2): Issue, verify, revoke; fetch evidence/metadata (with ETag/304 caching)
Security: Client mTLS enforcement, JWT, RBAC, rate limiting; vault/sidecar signing required in production to reduce key-exposure risk
Observability: Optional Prometheus /metrics, OpenTelemetry tracing, structured logs with PII controls
Provider attestations: Best-effort ingestion when available; local provenance and calibration snapshots as baseline
Deployment: Containers + Helm; cloud, on-prem (air-gapped with simulation), or hybrid
Note: CRYSTALS-Dilithium/Kyber represent NIST-selected post-quantum cryptography; PQC modules are not FIPS-validated across vendors. Classical cryptographic operations can leverage FIPS-validated modules where available. Transparency logging is optional and disabled by default.
Why teams choose FieldHash
✓ Physics-anchored evidence complements PQC—raising the cost to forge provenance beyond practical limits
✓ Local, offline verification—no vendor lock-in for long-term validation
✓ Non-exportable key custody—signing inside Vault/KMS/HSM boundaries
✓ Clear trust tiers—Strict typically requires hardware; Standard allows simulation (labeled)
