3.2.2.2 WPA/WPA2 encryption

Wi-Fi Protected Access 

(WPA)

 is an encryption method for WLAN. WPA contains the WEP architecture, but offers additional pro-

tection via dynamic codes, which are based on the Temporal Key Integrity Protocol (TKIP), and also offers pre-shared keys (PSK) or 

extensible authentication protocol (EAP) for user authentication. However, a radius server is required for this. 

WPA2

 is a development 

of WPA and uses a different encryption algorithm, advanced encryption standard (AES).

WPA offers two types of authentication, either 

pre-shared key

 or authentication via special 

authentication

 

protocols

, which are 

generally variations of EAP (Extensible Authentication Protocol). An authentication server 

(RADIUS server)

 is used for the latter 

authentication method, which is rarely used for private applications. Your administrator can give you the information you require to 

confi gure this authentication method.

The 

pre-shared key

 method is more common and offers a high degree of security.

To use

 WPA encryption

, select WPA-PSK under Authentication type and 

TKIP

 

under Encryption.

Now enter the code used in the 

WPA preshared key

 fi eld. The code entered must 

be absolutely identical with that used in the network. It must be min. 8 and max. 63 

random characters for ASCII. Letters (A-Z), numbers and punctuation marks can 

be used. 64 characters are required for HEX, whereby only characters from 0-9 

and a-f can be used. If you do not have this code, it can be found in your router/

access point or you can ask the person responsible for these devices.

Save the settings and click 

OK.

To use 

WPA2 encryption

, select 

WPA2-PSK

 under Authentication type and 

AES

 

under Encryption.

Now enter the code used in the WPA preshared key fi eld.

The code entered must be absolutely identical with that used in the network. It 

must be min. 8 and max. 63 random characters for ASCII. Letters (A-Z), numbers 

and punctuation marks can be used. 64 characters are required for HEX, whereby 

only characters from 0-9 and a-f can be used. If you do not have this code, it can be found in your router/access point or you can ask 

the person responsible for these devices.

Save the settings and click 

OK. 

To activate the profi le created, switch to the 

Profi les

 tab, select the profi le and then click 

Activate.
