Configuring Strong Wi-fi (802.1x) Authentication in Linux

“The transition from WEP to WPA to WPA2

“Back when the vulnerabilities of WEP encryption for Wi-Fi
networks were uncovered, the IEEE and wireless industry started
developing new protocols and standards. They came up with the
802.11i, a standard to finally implement a fully secure encryption
mechanism for wireless LANs. Before it was completed, the Wi-Fi
Alliance released the Wi-Fi Protected Access (WPA) encryption
standard, loosely based on 802.11i using TKIP for the underlying
encryption. Later they released WPA2, which includes full support
for 802.11i using AES/CCMP encryption.

“As many news outlets have discussed lately, there have been
more flaws found in the first version of WPA. However, unlike some
reports say, it hasn’t been cracked; full encryption keys or
passphrases haven’t been recovered. The flaws apply to the
underlying TKIP encryption and affects both the Enterprise and PSK
modes of the first version of WPA. This does not have anything to
do with WPA2, which uses a fully secure AES/CCMP encryption. Though
WPA currently provides adequate security, especially with long and
mixed character passphrases, you should try to migrate to WPA2–and
make sure you don’t use WEP at all.”
