Wlan Security Cipher (Client) - Siemens SIMATIC NET Configuration Manual

10.2.4.2

wlan security cipher (client)

Description
With this command, you configure the encryption method for the WPA(2) authentication.
Note
This command is only available in the client mode.
Note
iPCF or iPCF-MC mode enabled
If you want encryption with AES in iPCF or iPCF-MC mode, only keys with a 128 bit key
length are supported.
Requirement
You are in the Interface Configuration mode of the WLAN interface.
The command prompt is as follows:
cli (config-wlan-context-x)#
Syntax
Call up the command with the following parameters:
wlan security cipher { auto | wep | aes | tkip }
The parameters have the following meaning:
Parameter
auto
wep
aes
tkip
Note
The encryption method "TKIP" is not available with the transmission standards "802.11n"
and "802.11n only".

Description
TKIP or AES is used depending on the capability of the other station.
WEP (Wired Equivalent Privacy)
A symmetrical stream encryption method with only 40- or 104-bit long keys
based on the RC4 algorithm (Ron's Code 4).
AES (Advanced Encryption Standard): S trong symmetrical block encryption
method based on the Rijndael algorithm that further improves the functions of
TKIP.
TKIP (Temporal Key Integrity Protocol): A symmetrical encryption method with
the RC4 algorithm (Ron's
Code 4). In contrast to the weak WEP encryption, TKIP uses changing keys
derived from a main key.
