Support Resume on Reboot
When an OTA is downloaded, the RecoverySystem can be triggered to store
the user's lock screen knowledge factor in a secure way using the
IRebootEscrow HAL. This will allow the credential encrypted (CE)
storage, keymaster credentials, and possibly others to be unlocked when
the device reboots after an OTA.
