• LEAP: cracked 9 months ago, withheld by Cisco http://asleap.sourceforge.net/

• PEAP: Son of LEAP, less patents then LEAP, more secure. For now...

• 802.1x (don't confuse with 802.11x): EAP-Radius based. See http://www.open1x.org/

• Dynamic WEP: often combined with 802.1x Problems: Most of them operate in the card, so binary firmware only. Makes it more difficult to fix or upgrade too.

Notes:
