WPA (Wi-Fi Protected Access)
Wi-Fi Protected Access (WPA) is an improved security system for 802.11. It is part
of the 802.11i draft security standard. WPA encompasses TKIP (Temporal Key
Integrity Protocol) along with MIC (Message Integrity Check) and other xes to
WEP such as Weak IV (Initialization Vector) ltering and Random IV generation.
TKIP uses 802.1x to deploy and change temporary keys as opposed to static
WEP keys once used in the past. It is a signicant improvement over WEP. WPA
is part of a complete security solution. WPA also requires authentication servers in
enterprise security solutions.
