All of the advantages of 802.11i such asthe simple configuration and the powerful encryption with AES are thus avail-able for P2P mode, as are the improved security of the passphrase from theLANCOM Enhance Passphrase Security (LEPS).Encryption with 802.11i/WPATo activate the 802.11i encryption for a correctly configured P2P connection,adjust the settings for the first logical WLAN network in the appropriateWLAN interface (i.e. WLAN-1 if you are using the first WLAN module for theP2P connection, WLAN-2 if you are using the second module, e.g. as with anaccess point with two WLAN modules). 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.When set as P2P Master, the passphrase entered here will be used to checkthe Slave's authorization to access. When set as P2P Slave, the access pointtransfers this information to register with the remote site.
