Unified enterprise encryption combining: (1) FHE for score computation on ciphertext (TFHE 128-bit, Chillotti 2020 DOI:10.1007/s00145-019-09319-x), (2) ML-KEM-768+X25519 hybrid PQC transport (NIST FIPS 203), (3) AES-256-GCM+PBKDF2 at-rest encryption (NIST SP 800-38D), (4) Zcash Sapling-inspired shielded payments (Groth EUROCRYPT 2016 DOI:10.
Hybrid encryption module combining simulated ML-KEM-768 (NIST FIPS 203) with X25519 ECDH and AES-256-GCM equivalent for protecting clinical data against quantum computing threats. Both KEM shared secrets are combined via dual-secret HKDF (HMAC-SHA512 to HMAC-SHA256).

Patient-physician messaging over platforms like Telegram and WhatsApp transmits PHI in plaintext. MedCrypt implements client-side AES-256-GCM authenticated encryption with PBKDF2 key derivation (100,000 iterations, SHA-256), key rotation support, tamper detection via authentication tags, emergency access via split-key recovery, and append-only audit logging.
We implement client-side encryption for clinical messaging using AES-256-GCM authenticated encryption with PBKDF2 key derivation (100,000 iterations, SHA-256). Messages are encrypted in the browser before transmission; the server stores only ciphertext and cannot read message content.
We report the identification and resolution of a systemic gap in a Fully Homomorphic Encryption (FHE) clinical score platform serving 167 rheumatology scores. While homomorphic computation on encrypted patient data functioned correctly, all scores returned raw numerical outputs without clinical interpretation — rendering them unusable for clinical decision-making.
