• WEP: old 128bit, weak IV broke most WEP implementations: http://wepcrack.sourceforge.net/

• WEP+: fixed weak Ivs, 256bit, but it is still WEP

• WPA: worse then WEP for passphrase of less then 20 characters: http://wifinetnews.com/archives/002453.html Supported by Microsoft, more difficult with other OS.

• EAP: Extended Authentication Protocol. Many new layers to protect, layers “carry over” from previous crypto processing. Complex. Not unlikely to get broken. Projects to connect EAP with SIM and Radius, see http://www.wlansmartcard.org/
