![]() WPA, just like WEP, after being put through proof-of-concept and applied public demonstrations turned out to be pretty vulnerable to intrusion. WPA was a significant enhancement over WEP, but as the core components were made so they could be rolled out through firmware upgrades on WEP-enabled devices, they still relied onto exploited elements. WPA Enterprise uses an authentication server for keys and certificates generation. Most modern WPA applications use a pre-shared key (PSK), most often referred to as WPA Personal, and the Temporal Key Integrity Protocol or TKIP (/tiːˈkɪp/) for encryption. One year before WEP was officially abandoned, WPA was formally adopted. For the time the 802.11i wireless security standard was in development, WPA was used as a temporary security enhancement for WEP.
