Wireless Design & Development, September, 2006 by Pollock, Uriah; Shahid, Bilal; Zubair, Iftikhar

The security and privacy we have come to trust (primarily through wired networks) has quickly been disappearing, resulting in the requirement for a new form of network connection security. Wireless Ethernet tackled this problem not once, but twice. The second attempt, so far, looks to put an end to security problems "in-the-air" for Wi-Fi[TM].

Known as WPA2, or IEEE 802.11i, this latest security solution for wireless Ethernet is complex and involves numerous technologies and protocols--all working in conjunction to create a safe and secure network for everyday use. To better understand all the pieces in play in WPA2, we will take a quick look at Wi-Fi itself, the initial security solution that is now debunked, and then dig into the details behind 802.11i...
