WPA
WPA is a security protocol for WLAN. WPA uses a sophisticated key hierarchy that generates
new encryption keys each time a mobile device establishes itself with an AP. Protocols
including 802.1X, EAP, and RADIUS are used for strong authentication. Like WEP, keys can
still be entered manually (pre-shared keys); however, using a RADIUS authentication server
provides automatic key generation and enterprise-wide authentication. WPA uses temporal
key integrity protocol (TKIP) for data encryption. WPA2, also known as 802.11i, uses
advanced encryption standard counter mode CBC-MAC protocol (AES-CCMP) for data
encryption.
Field Description
Field Definition/Description
Select an SSID
and its
Security Level
If multiple SSID is enabled, use this drop-down menu to select the SSID that
you want to apply wireless security to.
WPA
Enables stations that support WPA v.1 to connect to the AP.
WPA2
Enables stations that support WPA v.2 to connect to the AP.
AnyWPA
Enables stations that support WPA v.1 and WPA v.2 to connect to the AP.
Enable WPA2
Pre-
authentication
Enables/disables WPA2 pre-authentication. This field is activated only when
WPA2 or AnyWPA is enabled.
Group Key
Interval
This value is measured in seconds.
Radius Server
When selected, the WPA stations authenticate with the RADIUS server using
extensible authentication protocol - transport layer security (EAP-TLS) over
802.1x.
IP Address
IP address of the RADIUS server.
Port
The protocol port of the RADIUS server.
Secret
The secret that the AP shares with the RADIUS server. You can enter up to
63 alpha-numeric characters in this field.
Pre-shared
Key
When selected, the WPA stations do not authenticate with the RADIUS
server using EAP-TLS. Instead they share a pre-shared secret with the AP
(ASCII format).
String
Pre-shared key string. The PSK string needs to be entered in the first-time
configuration of each station. You can enter 8 - 63 alpha-numeric characters
in this field.
