Command Usage 
Wi-Fi Protected Access (WPA) provides improved data 
encryption, which was weak in WEP, and user authentication, 
which was largely missing in WEP. WPA uses the following 
security mechanisms.
Enhanced Data Encryption through TKIP
WPA uses Temporal Key Integrity Protocol (TKIP). TKIP 
provides data encryption enhancements including per-packet 
key hashing (i.e., changing the encryption key on each 
packet), a message integrity check, an extended initialization 
vector with sequencing rules, and a re-keying mechanism. 
Enterprise-level User Authentication via 802.1x and EAP
To strengthen user authentication, WPA uses 802.1x and the 
Extensible Authentication Protocol (EAP). Used together, 
these protocols provide strong user authentication via a central 
RADIUS authentication server that authenticates each user on 
the network before they join it. WPA also employs “mutual 
authentication” to prevent a wireless client from accidentally 
joining a rogue network.
