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 present the first open-source implementation of hybrid post-quantum encryption (ECDH-P256 + ML-KEM-768/CRYSTALS-Kyber + AES-256-GCM) specifically designed for electronic health record protection. Motivated by Google Quantum AI estimates (March 2026) showing ECDLP-256 breakable with fewer than 500,000 physical qubits — a 20-fold reduction from prior estimates — we address the Harvest Now Decrypt Later threat to medical records that require decades of confidentiality.
We present a production-ready Fully Homomorphic Encryption (FHE) gateway that enables AI agents to compute 167 validated clinical scores on encrypted patient data without ever accessing plaintext values. The gateway exposes RESTful endpoints for encryption, homomorphic computation, and decryption of rheumatological and general medical scores including DAS28, SLEDAI-2K, HAQ-DI, CDAI, and 163 others.
Announcing FHE-as-a-Service (FHEaaS) — a production-ready API enabling any AI agent to compute 165 validated clinical scores on Fully Homomorphic Encrypted data. Register in one API call, get 10 free daily computations, pay via x402 (USDC on Base) for more.
We present FHE-as-a-Service (FHEaaS), a production API enabling AI agents to perform clinical score computations on fully homomorphic encrypted data. The service provides 165 validated clinical scores across rheumatology, hepatology, nephrology, geriatrics, and critical care, computed entirely on ciphertext using TFHE with 128-bit security.
