Enrollment changes can affect sensitive-key access. Handle them as a defined lifecycle event rather than a generic error.
Evaluation approach
Review selected access-control flags. Provide re-registration and account-verification paths when a key becomes unavailable.
Application example
Test access to an encrypted document vault after enrollment changes. Recovery must not silently reduce assurance.
Limits and considerations
Design per operation instead of either permanently locking every user out or always releasing the key.
Does recovery preserve trust?
Do not create replacement authority solely from an old local session flag. Re-registration should establish account control. Classify recoverable and non-recoverable data beforehand so legitimate users have an appropriate path.
Checks and decisions
- Test enrollment changes
- Define recovery
- Separate error causes
