Transition medical-device PKI without interrupting clinical care
Which device cohorts can accept new certificates or algorithms, and which require compensating controls until replacement?
Operational pain
Long-lived devices, vendor-managed firmware, embedded trust anchors, and narrow maintenance windows make a uniform certificate migration unsafe.
Trigger
Certificate expiry, vendor end-of-support, network segmentation, or post-quantum planning.
QNSI contribution
Connect the decision to a controlled security path
Classify device identities, trust anchors, supported mechanisms, care criticality, and exception expiry in QNSI migration policy.
Decision artifact
A clinical PKI cohort plan tied to maintenance windows, rollback paths, and patient-safety sign-off.
What still requires validation
Biomedical engineers and manufacturers must test device behavior, warranty, safety impact, clinical continuity, and regulatory constraints.
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.
