What kind of encryption does WPI use?
The WPI wireless network supports two levels of encryption. The stronger, recommended level is WPA2 with AES. For clients that do not support WPA2, such as Windows XP, WPA with TKIP encryption is also permitted. Please note, however, that WPA with TKIP is in the process of being phased out. While we continue to offer it, security research has begun finding weaknesses that, in time, will become full fledged vulnerabilities. Furthermore, 11n capable cards will not operate at full speed without using WPA2. Therefore, we strongly encourage anyone who is able to begin using WPA2 with AES-CCMP now. In addition, WPI requires a high level of authentication. Specifically, WPI requires 802.1x EAP-TLS certificate based authentication. This is sometimes referred to as WPA Enterprise. Note that devices which only support WPA Personal or Pre-Shared Key (PSK) will not work on the WPI network.
