802.11i

Wired Equivalent Privacy (WEP), the encryption algorithm implemented in current WLANs, is severely flawed and crackers can defeat it easily. In response, the IEEE is developing 802.11i as a new supplement to the 802.11 MAC standards in order to overcome the security weaknesses in Wi-Fi. 802.11i improves encryption, and the new Wi-Fi Alliance developed Wi-Fi Protected Access (WPA) encryption based upon a portion of the 802.11i standard. The next iteration of WPA, WPA2 will be fully compliant on the published 802.11i standard.
