Rekey Request [RKEY]
OTAR equipped radios only.
On radios equipped with over-the-air rekeying (OTAR), a radio user
can manually request an encryption rekey from the Key Management
Facility (KMF).
For a radio to receive encryption keys or keysets over-the-air, the
selected channel must be designated as an OTAR channel via PC
programming. Refer to your PC programming documentation for more
information.
To request a re-key:
Open the Rekey Request menu.
Press the “YES” button to Request Keys, or press “ESC” to cancel the
operation.
If the “YES” button is pressed while on a channel that has not been
marked as an OTAR channel, the radio will beep and “NON-OTAR” will
appear on the display.
If a successful rekey occurs, a tone will sound, and the display will
momentarily show “REKEYED”.
Keyset Viewing and Selecting [KSET]
OTAR equipped radios only.
The radio can hold up to 8 encryption keysets. Each keyset is limited to
a maximum of 64 keys. Only one keyset can be active at any time. The
radio will receive messages encrypted with any of the keys in any of the
keysets, but transmit keys can only be selected from the active keyset.
To change an encryption keyset, open the KEYST menu. Programmed
keyset labels will be displayed. Select the desired keyset and press
“ENTER”.
Zeroizing [ZERO]
The radio provides a method for the user to “panic-zeroize” all
encryption keys. Zeroizing removes all encryption keys from the radio,
including keys used for OTAR and Tactical OTAR operation.
Zeroize can be assigned as a button or menu list item.
Open the “Zeroize Keys” menu.
Press “YES” to erase all encryption keys or “ESC” to cancel the action.
When successfully removed the “Keys Removed” message will
momentarily be displayed.
