Traditional WEP encryption is being replaced because of the nuisance of changing keys, as well as being very easy to crack. There are several free programs available on the Internet to enable this unwanted aspect. The WPA protocol implements the majority of the IEEE 802.11i standard, and was intended as an intermediate measure to take the place of WEP while 802.11i was prepared. Specifically, Temporal Key Integrity Protocol (TKIP) was incorporated into WPA.
