Security for point-to-point connections

IEEE 802.11i can be used to attain a significant increase in the security of
WLAN point-to-point connections. All of the advantages of 802.11i such as
the simple configuration and the powerful encryption with AES are thus avai-
lable for P2P mode, as are the improved security of the passphrase from the
LANCOM Enhance Passphrase Security (LEPS).
Encryption with 802.11i/WPA
To activate the 802.11i encryption for a correctly configured P2P connection,
adjust the settings for the first logical WLAN network in the appropriate
WLAN interface (i.e. WLAN-1 if you are using the first WLAN card for the P2P
connection, WLAN-2 if you are using the second card, e.g. as with an access
point with two WLAN modules).

When set as P2P Master, the passphrase entered here will be used to check
the Slave's authorization to access. When set as P2P Slave, the access point
transfers this information to register with the remote site.
Configuration with For configuration with LANconfig you will find the encryption settings under
LANconfig
the configuration area 'Wireless LAN' on the '802.11i/WEP' tab.

The use of relay stations each equipped with two WLAN modules
simultaneously solves the problem of the "hidden station", by which
the MAC addresses of the WLAN clients are not transferred over mul-
tiple stations.
Activate the 802.11i encryption.
Select the method '802.11i (WPA)-PSK'.
Enter the passphrase to be used.
The passphrases should consist of a random string at least 22 charac-
ters long, corresponding to a cryptographic strength of 128 bits.
