113.2.3 Setting the Encryption for Bridge-Point to Point, Bridge Point to Multi-Point and Bridge WDSFirst, 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 fingerprint, 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 morecodes 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) encryptionClick the Set Security button to make the settings for the Bridge-Point to Point, Bridge-Point to Multi-Point and Bridge WDS modesafter setting the mode. For the Bridge WDS mode, encryption must be set for the access point under Wireless/Security Settingsin 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 EncryptionWired Equivalent Privacy (WEP) is a standard encryption algorithm for WLAN. It both controls the access to the network andguarantees 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 bitencryption. 128 bit encryption offers greater security. Thenselect either Hex (characters from 0-9 and a-f) or ASCII(any character) for the Key Format. This also determines thelength 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 withthe equired length.Examples:64 bit Hex (10 characters) = 231074a6ef64 bit ASCII (5 characters) = j31n.128 bit Hex (26 characters) = 231074a6b9773ce43f91a5bef3128 bit ASCII (13 characters) = urlaub2006.+0Click Apply to save your settings. You must then restart the router for the settings to take effect. To do so, click Apply in the nextwindow. The wireless network with encryption is available after you restart.
