Encryption
— When enabled, it forces the transceiver to use AES-128 encryption (RC4-128 on
iNET) on all over-the-air messages. This option requires the Encryption Phrase to be previously con-
figured. Both the AP and the Remote radios must use the same encryption phrase. (Some units may
not be authorized to use encryption. “See “Authorization Key Menu” on Page 89” for additional
details.) [
Enabled, Disabled; Disabled
]
•
Auto Key Rotation (AP only)
—When enabled, it forces the transceiver to use the key rotation algo-
rithm to generate a new encryption key after 500 kilobytes of information has been transmitted, or
one hour has elapsed. [
Enabled, Disabled; Disabled
]
•
Approved Access Points (RM only)/Remotes (AP only) List
—Displays a menu to manage the list of
other radios with which this unit will be permitted to communicate.
•
Encryption Phrase
—Phrase (text & numbers) that will be used by the encryption algorithm. [
8 to 29
alphanumeric characters; Blank
]
•
Force Key Rotation (AP only)
— Triggers an immediate rotation of the encryption keys regardless of
the internal rotation counters or the Auto Key Rotation setting being disabled.
Local Authentication—Approved Remotes/Access Points List Submenu
Setting the
Device Auth Method
to
Local
forces the transceiver to check the Approved List before a radio link
can be established. In the case of a Remote, the AP must be in the Approved Access Points List before it
accepts the beacon as being valid. In the case of an AP, a Remote must be in the Approved Remotes List to
be granted authorization.
Device Auth Method Local
requires at least one entry in the list for successful asso-
ciation.
This menu is the same for both Access Points and Remotes and the names change to reflect their mode.
Replace “Remotes” with Access Points” in the following description.
NOTE:
The limit for Remotes (in an Access Point radio) is 255. The limit for Access Points (in a Remote
radio) is 104.
