Executive summary
What this whitepaper covers
Modern medical devices must balance safety, functionality, and cybersecurity amid increasingly connected healthcare environments. This whitepaper unpacks the complexity of implementing cryptography — the foundation of digital trust — in medical devices. It explores the technical, regulatory, and operational factors that determine whether encryption and authentication mechanisms actually make devices more secure or inadvertently create vulnerabilities. Readers will learn how to align cryptographic design with FDA expectations, NIST recommendations, and real-world device constraints.
Why it matters
The regulatory and product context
Cryptography is often misunderstood or inconsistently applied in the medical device industry. Getting it wrong can undermine patient safety, delay regulatory approval, and damage brand reputation. As regulators tighten expectations around secure design, key management, and root of trust, medical device manufacturers must take a proactive approach. This whitepaper helps bridge the gap between theoretical cryptography and practical, compliant implementation across the device lifecycle.
Key insights
What you’ll take away
- Cryptography is not a plug-in—it requires system-wide planning from design through end-of-life.
- Effective key management and PKI design determine the success of any security architecture.
- Poorly chosen algorithms or shared keys can expose large device populations to attack.
- Resource constraints in implantable or portable devices necessitate carefully balanced crypto strategies.
- Regulators recognize the need for trade-offs but expect them to be well-documented and justified.
