What is the advantage of using WPA over WEP security?
In WPA, the encryption key is changed after every frame usingTemporary Key Integrity Protocol (TKIP). This protocol allows keychanges to occur on a frame by frame basis and to be automaticallysynchronized between the access point and the wireless clientrather than using a static key (using the same key on every frame)like WEP.
The result of this is that it is more difficult for a maliciousparty to gain unauthorised access to a secure network.
Starting with 802.11n (or Draft-11n), WEP is no longersupported; using WEP on devices that support Draft-11n will limitthem to the lower speed of 54 Mbps.
