Build the cryptography section of a medical-device premarket file
Is every cryptographic claim connected to a design requirement, implementation, verification result, and residual risk?
Operational pain
Algorithm lists and architecture diagrams fail review when they omit key generation, update, recovery, certificate, third-party, and lifecycle evidence.
Trigger
A connected-device submission or significant cybersecurity design change.
QNSI contribution
Connect the decision to a controlled security path
Export scoped QNSI algorithm, key, policy, provenance, and conformance references into the manufacturer's controlled technical file.
Decision artifact
A traceable crypto evidence index mapping claims to tests, artifacts, owners, and unresolved qualification work.
What still requires validation
The manufacturer owns the quality record, threat model, safety case, submission conclusions, and regulator interaction.
External problem context
Primary sources
These sources establish the external requirement or risk context. They do not endorse HEOSSI or prove that QNSI completed this scenario.
Evidence boundary
What this page does—and does not—prove
This is a product evaluation pattern, not a customer case study, certification, legal opinion, regulator endorsement, or claim that a production deployment completed the described work.
