Under the Shared Key authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel. To use Shared Key authentication, you must have a network key. WPA and WPA-PSK Authentication Short for Wi-Fi Protected Access, a Wi-Fi standard that was designed to improve upon the security features of WEP.
AT-WCU200G User’s Guide Under 802.11, a wireless station can be configured with up to four keys (the key index values are 0, 1, 2, and 3). When an access point or a wireless station transmits an encrypted message using a key that is stored in a specific key index, the transmitted message indicates the key index that was used to encrypt the message body. The receiving access point or wireless station can then retrieve the key that is stored at the key index and use it to decode the encrypted message body.
WPA Network Authentication: When choosing WPA Network Authentication a certificate is required from a certificate server and additional parameters must be configured in the Authentication tab. There are two selections for data encryption, choose one of the following: TKIP - Temporal Key Integrity Protocol. TKIP addresses the WEP static key problem by dynamically updating the key, based on WEP's own RC4 encryption across all devices once for every 10,000 packets transmitted WEP (802.
AT-WCU200G User’s Guide If you select Smart Card or other Certificate in EAP type, you can configure additional properties. If you select Properties in Smart Card or other Certificate Properties, do the following: ❑ To use the certificate that resides on your smart card for authentication, select Use my smart card. ❑ To use the certificate that resides in the certificate store on your computer for authentication, select Use a certificate on this computer.
Figure 25 Wireless Network Properties, Authentication Tab Configure WPAPSK on Windows XP 40 Select the Wireless Networks tab in the Wireless Network Connection Properties and highlight the appropriate wireless network in the Available Networks window. Select Configure and then select in Authentication.
AT-WCU200G User’s Guide WPA-PSK Network Authentication: When choosing WPA-PSK this option does not require a certificate, but it implements a Pre-shared Key which is a user defined encryption parameter. This is commonly used when a certificate is not available for clients. When selecting WPA-PSK TKIP, the Pre-shared Key must be entered into the Network Key field. See Figure 26.
WEP - Wireless Encryption Protocol. WEP incorporates a static key that must match on all devices that are within the same wireless network as identified by the SSID. The key you entered for an AP must match the key you enter for the client adapter. See Figure 27.
