Input String – If you select Input String, type the secret WEP key
string used for encrypting and decrypting in the Strings box. The
WEP Key box is automatically filled by the corresponding Hex code.
•WPA-PSK – Select to use a Pre-Shared Key (PSK), or shared secret for
authentication. WPA-PSK (Wi-Fi Protected Access Pre-Shared key) is a
security solution that adds authentication to enhanced WEP encryption
and key management. WPA-PSK mode does not require an
authentication server. It is suitable for home or small office.
To enable WPA v1 encryption, select WPA v.1. If WPA v.1 is enabled,
click one of the following encryption types from the Encryption drop-
down list:
•Auto – The AP will advertise both TKIP and CCMP (Counter Mode
with Cipher Block Chaining Message Authentication Code Protocol)
for WPAv1. CCMP is an IEEE 802.11i encryption protocol that uses
the encryption cipher AES (Advanced Encryption Standard). Auto is
the default.
TKIP only – The AP will advertise TKIP as an available encryption
protocol for WPAv1. It will not advertise CCMP.
To enable WPA v2-type encryption, select WPA v.2. The other options for
this drop-down list are:
•Auto – If you click Auto, the Wireless AP advertises both TKIP and
CCMP (counter mode with cipher block chaining message
authentication code protocol). CCMP is an IEEE 802.11i encryption
protocol that uses the encryption cipher AES (Advanced Encryption
Standard). Auto is the default.
AES only – If you click AES, the Wireless AP advertises CCMP as an
available encryption protocol. It will not advertise TKIP.
To enable re-keying after a time interval, select Broadcast re-key
interval. If this checkbox is not selected, the Broadcast encryption key is
never changed and the Wireless AP will always use the same broadcast
key for Broadcast/Multicast transmissions. This will reduce the level of
security for wireless communications.
In the Broadcast re-key interval box, type the time interval after which
the broadcast encryption key is changed automatically. The default is
3600.
In the Pre-shared key box, type the shared secret key to be used
between the wireless device and Wireless AP. The shared secret key is
used to generate the 256-bit key.
Mask/Unmask – Click to display or hide your shared secret key.
17. Click Next. The Radio Assignment screen is displayed.
