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 preprogrammed by a qualified radio technician. Check with your
dealer or system administrator for more information.

Requesting Rekey

keys.

provisioned. This secret UKEK must be established before a Rekey Request delivers the updated
keys.
