" Open System: An SU configured to Open System can be
authenticated only by an AU that is also configured to Open
System. The WEP algorithm is not used.
" Shared Key: Authentication enabled. The authentication
messages are encrypted. An SU configured to use Shared Key
can be authenticated only by an AU configured to use Shared
Key, provided they both use the same WEP Key. Both the WEP
Key number and the WEP Key should be identical at both sides
of the link.
" Support All (AU only): The AU authenticates all SUs, regardless
of the Authentication Algorithm and WEP Key configured in the
SU. This is intended primarily for installations with possible
“stolen” SUs. In such cases, initial authentication will be in this
mode, and the mode will be changed to Shared Key only after
configuring appropriate WEP Keys in the AU as well as in all
associated SUs, excluding known “stolen” SUs that belong to the
Black List.
If the required algorithm is Shared Key, do the following:
• Define at least one of the four WEP Keys by selecting one
of them from the Security Parameters menu and entering
the required key.
• In an SU, select Default Key ID from the Security
Parameters menu and enter the number of a defined
WEP key.
• Select Authentication Algorithm from the Security
Parameters menu.
The Authentication Algorithm menu opens.
• Select Shared Key.
The default is Open System.
! Default Key ID (SU Only)– Defines the ID of the key to be used for
encryption of transmitted authentication messages and decryption
of received authentication messages.
Valid values are from 1 to 4.
The default is WEP KEY # 1.
! WEP KEY # 1 through WEP KEY # 4 – Enters the encryption key to
be used for initialization of the pseudo-random number generator
used in the RC4 encryption process. At least one WEP Key must be
configured before the Shared Key authentication mode can be used.
The Subscriber Unit must use the same WEP Key that is used by
the Access Unit.
The WEP Key is a string of 10 hexadecimal numbers.
NOTE:
The Shared Key option cannot be selected until at least one WEP Key is
configured. In the SU the appropriate Default Key ID must also be
configured.
