Wi-Fi Protected Access
WPA

   <networking, security> (WPA) A security scheme for {wireless
   networks}, developed by the networking industry in response to
   the shortcomings of {Wired Equivalent Privacy} (WEP).  WPA
   uses {Temporal Key Integrity Protocol} (TKIP) {encryption} and
   provides built-in {authentication}, giving security comparable
   to {VPN} tunneling with WEP, with the benefit of easier
   administration and use.

   {WPA-PSK} is a simplified form of WPA.
