• WPA 802.1X (or just WPA) provides a scheme of mutual authentication using either
IEEE 802.1x / Extensible Authentication Protocol (EAP) authentication or pre-shared
key (PSK) technology. It provides a high level of assurance to enterprises, small
businesses and home users that data will remain protected and that only authorized
users may access their networks. For enterprises that have already deployed IEEE
802.1x authentication, WPA offers the advantage of leveraging existing authentication
databases and infrastructure.
• WPA2 802.1X, like WPA, supports IEEE 802.1x / EAP authentication or PSK
technology. It also includes a new advanced encryption mechanism using the
Advanced Encryption Standard (AES). AES is required for corporate and government
users. The difference between WPA and WPA2 is that WPA2 provides data
encryption via the AES, whereas WPA uses the Temporal Key Integrity Protocol
(TKIP).
• WEP 802.1X is a special mode for using IEEE 802.1x / EAP technology for
authentication and WEP keys for data encryption.
Data Encryption: All devices in the network should use the same encryption method.
The drop-down menu offers four options.
• Disabled disables the WEP data encryption.
• WEP enables the WEP data encryption. When this is selected, you need to
continue with the setting of the WEP encryption keys.
• TKIP (Temporal Key Integrity Protocol) changes the temporal key every 10,000
packets. (A packet is a kind of message transmitted over a network.) This ensures
much greater security than standard WEP security.
