Any software described in this manual is sold or licensed "as is". [. . . ] Note that in Windows Vista, the adapter only supports Open System, Shared Key, WPA-PSK and WPA2-PSK security methods. Open System ­ No authentication is needed among the wireless network. Shared Key ­ Only wireless stations using a shared key (WEP Key identified) are allowed to connecting each other. WPA-PSK ­ It is a special mode designed for home and small business users who do not have access to network authentication servers. In this mode, known as Pre-Shared Key, the user manually enters the starting password in their access point or gateway, as well as in each wireless stations in the network. WPA-PSK takes over automatically from that point, keeping unauthorized users that don't have the matching password from joining the network, while encrypting the data traveling between authorized devices. WPA2-PSK ­ WPA2-PSK is also for home and small business. The difference between WPA-PSK and WPA2-PSK is that WPA2PSK provides data encryption via the AES. In contrast, WPA-PSK uses Temporal Key Integrity Protocol (TKIP). WPA 802. 1X ­ 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. Network Authentication 22 WPA2 802. 1X ­ Like WPA, WPA2 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 to the corporate user or government users. The difference between WPA and WPA2 is that WPA2 provides data encryption via the AES. In contrast, WPA uses Temporal Key Integrity Protocol (TKIP). WEP 802. 1X ­ It's a special mode for using IEEE 802. 1x/EAP technology for authentication and WEP keys for data encryption. Data Encryption Disabled ­ Disable the WEP Data Encryption. WEP ­ Enable the WEP Data Encryption. When the item is selected, you have to continue setting the WEP Encryption keys. TKIP ­ 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 insures much greater security than the standard WEP security. AES ­ AES has been developed to ensure the highest degree of security and authenticity for digital information and it is the most advanced solution defined by IEEE 802. 11i for the security in the wireless network. [. . . ] TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security, especially the reuse of encryption keys. TKIP is involved in the IEEE 802. 11i WLAN security standard, and the specification might be officially released by early 2003. AES (Advanced Encryption Standard), a chip-based security, has been developed to ensure the highest degree of security and authenticity for digital information, wherever and however communicated or stored, while making more efficient use of hardware and/or software than previous encryption standards. It is also included in IEEE 802. 11i standard. [. . . ]
