Encryption Type: Select the encryption type (TKIP or AES) for data encryption.
WPA/WPA2 Pre-Shared Key: Pre-Shared key mode (PSK, also known as Personal mode)
is designed for home and small office networks that cannot afford the cost and complexity of
an 802.1x authentication server. Each user must enter a pass phrase to access the network.
It can be a password like "jeanY-13a"; a pass phrase like "Idaho bung gear id gene", or a
hexadecimal string like "65E4 E556 8622 EEE1"
WPA ReKey Method: Specify the Reky method ( by Time or by Packet). Default: Disable.
Pairwise Master Key Cache Interval: In the Fast Roaming section, you can configure
Pairwise Master Key (PMK) caching and pre-authentication options.
PMK Cache Interval – The number of minutes before deletion (and renewal) of the Pairwise
Master Key used for Authentication.
Pre-Authentication Support: Enable/Disable pre-authentication support. Default: Disable.
According to some of the preferred embodiments, a method for proactively establishing a
security association between a mobile node in a visiting network and an authentication agent
in another network to which the mobile node can move includes: negotiating pre-
authentication using a flag in a message header that indicates whether the communication is
for establishing a pre-authentication security association; and one of the mobile node and the
authentication agent initiating pre-authentication by transmitting a message with the flag set in
its message header, and the other of the mobile node and the authentication agent
responding with the flag set in its message header only if it supports the pre-authentication.
