WPA-PSK

WPA-PSK is an extra-strong encryption where encryption keys are

automatically changed (called rekeying) and authenticated between

devices after a specified period of time, or after a specified number of

packets has been transmitted.

WPA-PSK is far superior to WEP and provides stronger protection for

the home/SOHO user for two reasons. The process used to generate the

encryption key is very rigorous and the rekeying (or key changing) is

done very quickly. This stops even the most determined hacker from

gathering enough data to break the encryption.

WPA-Shared Key

This is used by the clients to become authenticated with the Root

Bridge/Remote Router/Remote NAT.

WPA-RADIUS:

WPA provides encryption via the Temporary Key Integrity Protocol (TKIP) using the RC4 algorithm. It is

based on the 802.1X protocol and addresses the weaknesses of WEP by providing enhancements such

as Per-Packet key construction and distribution, a message integrity code feature and a stronger IV

(Initialization Vector).The length of a WPA key is between 8 and 63 characters.
