What are the Key Features of WPA and WPA2 Security? How Does WPA Compare to WPA2 IEEE 802.11i?The primary information conveyed in the Beacon frames is the authentication method and the cipher suite. Possible authentication methods include 802.1X and Pre-shared key. Pre-shared key is an authentication method that uses a statically configured pass phrase on both the stations and the access point. This obviates the need for an authentication server, which in many home and small office environments will not be available nor desirable. Possible cipher suites include WEP, TKIP, and AES Advanced Encryption Standard. We talk more about TKIP and AES when addressing data privacy below WPA/WPA2 Authentication Enterprise-level User Authentication via 802.1x/EAP and RADIUSWireless LAN Wired Network with Optional 802.1x Port Based Network Access Control2.
