4.6.3.4 Wireless – Security – 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.
Figure below shows the default setting of the
