Encryption
Your handset supports non-encrypted data transmission and encrypted
data transmission with WEP, WPA and WPA-PSK methods of encryption. For
WPA and WPA-PSK the encryption algorithm TKIP is used.
Open the Encryption list and select the method of encryption that is used.
Depending on the selected method of encryption, additional fields appear
in which you have to state the key or password.
The values you enter must coincide with the security settings configured on
the access point/WLAN router.
None
None of the data in the WLAN is encrypted when transmitted.
WPA-PSK
The WPA-PSK procedure (WI-FI Protected Access with Pre-Shared Key) uses
subscriber-specific keys. These are generated from a Pre-Shared Key and the
MAC address of the device concerned and automatically changed at
periodic intervals (rekeying interval). The complex TKIP algorithm is used
for the encryption. The Pre-Shared Key is defined at the access point/WLAN
router and is the same for all WLAN subscribers.
You must enter the following:
– Encryption Type
The
TKIP method of encryption is set.
– Pre-Shared Key
Enter the Pre-Shared Key of the access point/WLAN router for gene-
rating the key. If you enter a Pre-Shared Key in ASCII format it can be
between 8 and 63 characters long. If you enter a Pre-Shared Key in
hexadecimal format it must be exactly 64 characters long.
WEP
WEP (Wired Equivalent Privacy) is the standard encryption for WLAN
networks. Here the same key is used by all subscribers to the WLAN and the
access point/WLAN router for encrypting and decrypting data. WEP distin-
guishes between 64 and 128 bit encryption.
You must enter the following:
– WEP Mode
Specify the WEP key length configured in the access point/WLAN
router by clicking on the relevant option.
– WEP Key
Enter the WEP key configured in the access point/WLAN router. The
key can be entered in ASCII or hexadecimal format. In ASCII format
the characters 0 to 9 and A to Z, plus the special characters in the AS-
CII character set, are permitted. In hexadecimal format the charac-
ters 0 to 9 and A to F are permitted.
