Quick question for you guys.

What are some other types of wireless encryption besides WEP?

There's WPA (Wi-Fi Protected Access).... I heard WPA2 is being developed as well but I don't know too much about it.

WEP, as you know, is the most common. There are a few variations on WEP as well - some are standardized and others are proprietary. Some companies like Nokia have begun to use nonstandard RC4 key lengths and other companies like Demarc have tried maniuplating the key scheduling algorithm.

WPA is also another encryption method that most people are aware of. WPA-PSK is the only form I'm aware of.

802.1x/RADIUS is a form of encryption/authentication that was originally intended for Ethernet and dialup-ppp, but it's been used heavily in WiFi lately to make up for the shortcomings of WEP.

VPN tunneling is also used frequently when security is a priority.

On the front of technology right now we have 802.11i which was a task group formed specificaly to address the issues with WiFi security. The two main results of 802.11i are TKIP and CCMP.

If you want to keep up to date on WiFi security I'd suggest following the 802.11i task groups progress and reading WiFi News (http://wifinetnews.com/) every now and then to keep up.
