Encryption for Medical Devices

For protecting PHI on a medical device, use modern cryptographic algorithms like AES-GCM, ChaCha20-Poly1305, and SHA-256 to ensure data confidentiality and integrity. These vetted primitives provide robust protection for sensitive patient health information.

To implement secure over-the-air updates, encrypt the firmware image and ensure its integrity during transmission using robust cryptographic mechanisms. This protects the update payload from tampering and unauthorized access while maintaining device safety.

Yes, TLS 1.3 is recommended for securing data in transit on medical devices. It provides modern transport security that protects sensitive health information and credentials as they move between the device and external systems.

The best way to handle key management for medical device security is to follow best practices for secure key derivation, robust randomness, and secure key storage. This ensures cryptographic keys are generated and protected against unauthorized extraction.

You need to consider FIPS requirements for your medical device cryptography to ensure regulatory compliance. Using vetted cryptographic libraries and FIPS-validated primitives guarantees that your data protection mechanisms meet required healthcare security standards.

To encrypt data at rest on a medical device, apply secure storage encryption mechanisms using vetted libraries and modern algorithms. This protects stored PHI, PII, credentials, and safety-control data from unauthorized physical or logical access.
