Introduction

Clearly the shortcomings of WEP limit its usefulness in an enterprise context. The IEEE has been hard at work in the 802.11i Task Group to develop a replacement for WEP. Originally called WEP2, the name was changed to WPA, which is, as mentioned earlier, short for Wi-Fi Protected Access.

According to rumors inside the Wi-Fi Alliance, the running joke was: “After the ship sinks, you don't name the next one Titanic 2.” On October 31, 2002, the Wi-Fi Alliance announced WPA, in essence a compromise solution because parts of the 802.11i specification were ready (such as 802.1x and Temporal Key Integrity Protocol [TKIP]) and other parts were not (such as Advanced Encryption Standard [AES] and secure deauthentication/disassociation).
