Authentication Type:
The ADSL Router supports two
authentication types: Open System
and Shared key. This should be
considered with the WEP (Wired
Equivalent Privacy) mechanism.
Open System means that it allows any client
to authenticate and attempt to communicate
with a bridge. The client can only
communicate if its WEP keys match the
router’s WEP keys.
Shared Key means that a bridge or router
will send an unencrypted text string to any
client attempting to communicate with the
router. The client requesting authentication
encrypts the text and sends back to the
router. Both unencrypted and encrypted can
be monitored, yet it leaves the bridge open to
be attacked by any intruder if he calculates
the WEP key by comparing the text strings.
That is why shared key authentication can be
less secure than open authentication.
Format:
Choose the form of encryption key.
You have to select either
Hexadecimal digits or ASCII
characters and type the keys on the
fields of Key 1 to Key 4.
Key 1 to 4:
Fill out the WEP keys according to the
key length. For 64-bit WEP mode, the
content you can type is 5 characters
or 10 hexadecimal digits. For 128-bit
WEP mode, the content you can type
is 13 characters or 26 hexadecimal
digits.
Default Transmission Key:
Select one of the network keys that
you set on the Key boxes as the
default one.
Click Apply for activation when the
settings are done.
