Infinite UKEK Retention
This feature enables Unique Key Encryption Key (UKEK) to be permanently stored in the radio even when all
the encryption keys are erased. Without this UKEK key, the radio cannot be rekeyed over the air. The Infinite
UKEK Retention settings can be different for each secure profile.
NOTE: This feature must be programmed by a qualified radio technician. For more information, contact
your system administrator.

Requesting Rekey
Over-the-Air Rekey (OTAR), allows the system administrator to remotely reprogram encryption keys in the
radio. The Rekey Request feature allows you to request for the reprogramming of the encryption keys.
Prerequisites: Ensure that at least one initial secret Unique Key Encryption Key (UKEK) has been
provisioned. This secret UKEK must be established before a Rekey Request delivers the updated keys.
