D-Link Unified Access Point Administrator's Guide When to Use WPA Personal Wi-Fi Protected Access Personal Pre-Shared Key (PSK) is an implementation of the Wi-Fi Alliance IEEE 802.11i standard, which includes AES-CCMP and TKIP mechanisms. This mode offers the same encryption algorithms as WPA 2 with RADIUS but without the ability to integrate a RADIUS server for user authentication. This security mode is backwards-compatible for wireless clients that support only the original WPA. Key Management WPA Personal provides dynamically-generated keys that are periodically refreshed. There are different Unicast keys for each station. Encryption Algorithms TKIP AES-CCMP User Authentication The use of a PSK provides user authentication similar to that of shared keys in WEP. Recommendations WPA Personal is not recommended for use with the Unified Access Point when WPA Enterprise is an option. We recommend that you use WPA Enterprise mode instead, unless you have interoperability issues that prevent you from using this mode. For example, some devices on your network might not support WPA or WPA2 with EAP talking to a RADIUS server. Embedded printer servers or other small client devices with very limited space for implementation might not support RADIUS. For such cases, we recommend that you use WPA Personal. When to Use WPA Enterprise Wi-Fi Protected Access Enterprise with RADIUS is an implementation of the Wi-Fi Alliance IEEE 802.11i standard, which includes AES-CCMP and TKIP mechanisms. This mode requires the use of a RADIUS server to authenticate users. On the Unified Access Point, WPA Enterprise provides the best security available for wireless networks. This security mode also provides backwards-compatibility for wireless clients that support only the original WPA. Key Management WPA Enterprise mode provides dynamically-generated keys that are periodically refreshed. There are different Unicast keys for each station. Encryption Algorithms TKIP AES-CCMP User Authentication RADIUS Recommendations WPA Enterprise mode is the recommended mode. The AES-CCMP and TKIP encryption algorithms used with WPA modes are far superior to the RC4 algorithm used for Static WEP or IEEE 802.1X modes. Therefore, AES-CCMP or TKIP should be used whenever possible. All WPA modes allow you to use these encryption schemes, so WPA security modes are recommended above the other modes when using WPA is an option. 42 © 2001-2008 D-Link Corporation.
