WPA (Wi-Fi Protected Access) - WPA is a security technology for wireless networks that improves

on the authentication and encryption features of WEP (Wired Equivalent Privacy). In fact, WPA

was developed by the networking industry in response to the shortcomings of WEP. One of the

key technologies behind WPA is the Temporal Key Integrity Protocol (TKIP). TKIP addresses the

encryption weaknesses of WEP. Another key component of WPA is built-in authentication that

WEP does not offer. With this feature, WPA provides roughly comparable security to VPN

tunneling with WEP, with the benefit of easier administration and use. This is similar to 802.1x

support and requires a RADIUS server in order to implement. The Wi-Fi Alliance will call this,

WPA-Enterprise. One variation of WPA is called WPA Pre Shared Key or WPA-PSK for short - this

provides an authentication alternative to an expensive RADIUS server. WPA-PSK is a simplified

but still powerful form of WPA most suitable for home Wi-Fi networking. To use WPA-PSK, a

person sets a static key or "passphrase" as with WEP. But, using TKIP, WPA-PSK automatically

changes the keys at a preset time interval, making it much more difficult for hackers to find and

exploit them. The Wi-Fi Alliance will call this, WPA-Personal.
