H33-Health — Post-Quantum HIPAA Compliance

Here’s what happens when you store, verify, and compute on PHI with H33-Health.

Step 01 — Kyber-1024 Encrypted PHI Storage

Field-Level Post-Quantum Encryption

Patient records encrypted at the field level. SSN, allergies, labs — each field individually encrypted with Kyber-1024 key encapsulation. Even a full database breach reveals nothing. No plaintext PHI ever touches your servers, logs, or any intermediate cache. HIPAA §164.312(a)(2)(iv) encryption requirements satisfied by NIST post-quantum standards, not legacy AES that quantum computers will break.

Step 02 — Zero-Knowledge Eligibility Verification

Prove Without Transmitting PHI

Prove a patient is insured, has a valid Rx, or meets clinical trial criteria without transmitting the underlying PHI. The verifier learns only true or false — nothing else. Insurance eligibility, prescription legitimacy, age thresholds, diagnostic criteria — all verified with zero-knowledge proofs. The data stays encrypted, the answer is mathematically guaranteed.

Step 03 — FHE Computation on Encrypted Records

Analytics Without Decryption

Run aggregate queries across encrypted patient data. Clinical trial matching, population health analytics, outcome tracking — all without decrypting a single record. Fully homomorphic encryption lets you compute on ciphertext and get the correct plaintext result. Researchers never see individual PHI. IRB-compliant by design, not by policy.

Step 04 — Dilithium-Signed Audit Trails

Tamper-Proof Compliance Proof

Every PHI access, verification, and computation produces a post-quantum tamper-proof audit entry signed with Dilithium-3 (FIPS 204). HIPAA §164.312(b) compliance is not a checkbox — it’s a mathematical guarantee. Auditors verify signatures, not trust. Generate compliance reports on demand with cryptographic proof of every access, every query, every result.

Every healthcare workflow touches PHI. None of them need to expose it.

Insurance Eligibility

Hospital proves patient has active coverage without sending SSN or policy details to the insurer. Zero-knowledge proof of eligibility — the insurer learns only true or false.

has_active_coverage(patient_id, procedure_code) → true/false

Prescription Verification

Pharmacy verifies Rx validity and prescriber credentials without accessing full medical history. Zero-knowledge proof of prescription legitimacy — no PHI transmitted.

verify_rx(rx_id, prescriber_npi) → valid/invalid

Clinical Trial Matching

Run FHE queries across thousands of encrypted patient records to find eligible candidates. Researchers never see individual PHI. IRB-compliant by design, not by policy.

fhe_match(criteria, encrypted_cohort) → [eligible_ids]

Lab Result Sharing

Encrypted results in Vault, ZK proof of “value within normal range” for insurance or employer wellness programs — without revealing the actual numbers.

in_normal_range(lab_result, reference) → true/false

The more you protect, the less each operation costs.

HIPAA Technical Safeguards — Mapped to H33-Health

Every HIPAA §164.312 technical safeguard requirement mapped to a specific H33-Health cryptographic feature. Not policy-based — mathematically provable.

HIPAA Section	Requirement	H33-Health Feature	Tier
§164.312(a)(2)(iv)	Encryption & decryption	Kyber-1024 field-level encryption	Health-0+
§164.312(b)	Audit controls	Dilithium-signed tamper-proof logs	Health-0+
§164.312(c)(1)	Integrity controls	Post-quantum signatures on all records	Health-1+
§164.312(d)	Person / entity authentication	ZK eligibility verification	Health-1+
§164.312(e)(1)	Transmission security	Kyber-1024 key encapsulation in transit	Health-0+
§164.314(a)	Business associate contracts	Automated BAA management	Health-3
§164.530(j)	Record retention (6 years)	Encrypted immutable audit archive	Health-2+

Compliance is not a checkbox — every requirement above is enforced by post-quantum cryptographic primitives, not access control policies.

Frequently Asked Questions

How does H33-Health satisfy HIPAA encryption requirements?

H33-Health uses BFV fully homomorphic encryption (FHE) to process Protected Health Information (PHI) without ever decrypting it. Data remains encrypted during computation. This exceeds HIPAA's encryption-at-rest and encryption-in-transit requirements by adding encryption-in-use.

What is zero-knowledge eligibility verification?

A health plan can verify a patient's eligibility without seeing the patient's actual medical records. The computation runs on encrypted data using FHE, and the result (eligible/not eligible) is returned without exposing any PHI fields.

Can H33-Health work with existing EHR systems?

Yes. H33-Health provides a REST API that accepts standard HL7 FHIR resources. Your EHR system encrypts PHI client-side before sending. The API processes encrypted payloads and returns encrypted results that only the authorized recipient can decrypt.

How does FHE computation work on PHI?

Protected Health Information is encrypted with BFV (lattice-based FHE). The H33 server performs computations — eligibility checks, risk scoring, claims adjudication — directly on the ciphertext. The server never sees plaintext PHI at any point.

What is the latency for an encrypted eligibility check?

A single FHE eligibility verification completes in approximately 1-2 milliseconds using BFV batching. The Dilithium attestation adds ~191 microseconds. Total end-to-end: typically under 5 milliseconds.

How does the Dilithium audit trail work?

Every computation on encrypted PHI produces a Dilithium (ML-DSA) signed attestation recording the operation type, timestamp, data fields accessed (by encrypted reference, not plaintext), and result hash. This creates a HIPAA-compliant, tamper-proof audit trail that survives quantum attacks.

Can patients verify their own data was handled correctly?

Yes. Each computation produces a Dilithium-signed receipt that patients can independently verify. The receipt proves what computation was performed, when, and that the result matches the input, without revealing the actual data.

How does H33-Health handle cross-state insurance queries?

FHE enables cross-jurisdiction queries without violating state-specific privacy laws. Since data never leaves encrypted form, no plaintext PHI crosses state boundaries. The computation runs on ciphertext, and only the authorized insurer can decrypt the result.

Is H33-Health compatible with HL7 FHIR?

Yes. H33-Health accepts FHIR R4 resources (Patient, Coverage, Claim, ExplanationOfBenefit) wrapped in an encrypted envelope. The API maps FHIR resource fields to FHE computation slots. Response payloads follow FHIR OperationOutcome format.

What PHI fields are encrypted at rest?

All 18 HIPAA identifiers are encrypted with BFV FHE: name, address, dates, SSN, medical record numbers, health plan IDs, account numbers, certificate numbers, device IDs, URLs, IPs, biometric identifiers, photos, and any other unique identifying characteristic.

HIPAA compliance you can prove mathematically, not just promise.
