o
WPA-TKIP.
Authentication via 802.1x/EAP, and encryption via TKIP (Temporal
Key Integrity Protocol), a hardened version of the older WEP standard. The key
is updated automatically and transparently with DES (Data Encryption
Standard) or AES (Advanced Encryption Standard) encryption.
This option provides the highest level of security, but it requires users to have
a WPA client (which is built into recent versions of Windows XP, Mac OS X,
and Linux).
NOTE
The
WPA
option requires you to configure at least one Radius
server on the Access Point Configuration page.
When
WPA
is selected, a
Pre-Shared Key
checkbox and
Passphrase
entry field
appear.
o WPA-AES:CCMP.
The complete 802.11i / WPA2 standard, replacing WEP/DES
and TKIP with a specific mode of AES called CCMP (Counter-Mode/CBC-MAC
Protocol. which uses Cipher Block Chaining-Message Authentication Code).
CCMP provides both data confidentiality (encryption) and data integrity. This
is the highest security option you can choose, but some legacy 802.11 clients
may not support it.

o WPA-PSK.
Also known as WPA-Personal; enables a single shared password for
access to this WLAN. TKIP is still used to create automatic and transparent key
updates, thereby making WPA-PSK secure from an encryption standpoint. It’s
