Description
The AP uses 802.1x to communicate with a
RADIUS server and authenticate clients.
The AP generates and distributes dynamic,
per user encryption keys (based on the
Temporal Key Integrity Protocol (TKIP)) to
each client following successful
authentication. WPA mode provides
message integrity checking to guard
against replay type attacks. This mode is
not available for all radio types.
The AP uses a Pre-shared Key (manually
configured on both the AP and the clients)
to authenticate clients. The AP generates
and distributes dynamic, per user
encryption keys (based on TKIP) to each
client following successful authentication.
This mode is for customers who want to use
WPA but do not have a RADIUS server
installed on their network. This mode is not
available for all radio types.
