3.2.3 Setting the Encryption for Bridge-Point to Point, Bridge Point to Multi-Point and Bridge WDS
First, it is important to understand a range of terms. The next section will explain the main terms used here:
Authentication
: Authentication is a process in which the identity, e.g. of a person is determined based on a certain characteristic.
This can be done by fi ngerprint, password or any other proof of authorisation.
Encryption
: Encryption is a process in which plain text is transformed into a coded text via an encryption process (algorithm). One or more
codes can be used for this. It must also be mentioned that each individual encryption process offers one or more authentication options.
The following encryption types are available for the various modes:
•
64 Bit and 128 Bit WEP encryption
•
WPA (TKIP) and WPA2 (AES) encryption
Click the
Set Security
button to make the settings for the
Bridge-Point to Point, Bridge-Point to Multi-Point and Bridge WDS
modes
after setting the mode. For the
Bridge WDS
mode, encryption must be set for the access point under
Wireless/Security Settings
in the menu on the left. This is the only encryption available for WDS.
For WDS, the encryption must be adjusted before, in the menu on the left, under Wireless/Security Settings.
You can choose either
WEP
encryption with
64 Bit
and
128 Bit, WPA
with
TKIP
encryption algorithm and
WPA2 with AES
encryption algorithm.
3.2.3.1 WEP Encryption
Wired Equivalent Privacy
(WEP)
is a standard encryption algorithm for WLAN. It both controls the access to the network and
guarantees the integrity of the data. This method is considered vulnerable due to a range of weaknesses.
First select whether you want to use 64 bit or 128 bit
encryption. 128 bit encryption offers greater security. Then
select either Hex (characters from 0-9 and a-f) or ASCII
(any character) for the
Key Format
. This also determines the
length of the key.
Default Key
allows you to select one of four preset keys.
Select
Key 1
, for example, and enter your key of choice with
the equired length.
Examples:
64 bit Hex (10 characters) = 231074a6ef
64 bit ASCII (5 characters) = j31n.
128 bit Hex (26 characters) = 231074a6b9773ce43f91a5bef3
128 bit ASCII (13 characters) = urla0
Click
Apply
to save your settings. You must then restart the router for the settings to take effect. To do so, click
Apply
in the next
window. The wireless network with encryption is available after you restart.
