-27-Privacy Configuration consists of specifying Security and Certification, as explained in the following: Security Tab In order to join a network, networks may require an encryption key for association. You must configure the Authentication Mode and Encryption Mode for your keys in the Privacy section of this menu. For Authentication Mode: Open: Requires NO authentication, since it allows any device to join a network without performing any security check. Shared: Requires that the station and the access point use the same WEP key to authenticate. This basically means that WEP must be enabled and configured on both the access point and the client with a same key, showed as below:

-28-WPA-PSK: Allows you to gain access to a secured wireless network that the station and the access point use the same pre-shared key to authenticate. You must type a mixture of numbers and letters in the Pre-shared key [WPA] section of this menu. You may input either 8-63 ASCII characters or 64 HEX characters. Pre-shared key is usually used for SOHO authentication.

-29-WPA: Allows you to gain access to a more secured wireless network that requires mutual authentication between client and access point with a Radius authentication server. This product supports various EAP types, which require different credential authentication. In order to access the wireless network, you must select EAP type your service provider supplied in the section of IEEE802.11X Authentication.

-30-WPA2-PSK: Like WPA, WPA2-Personal offers authentication via a pre-shared key. Pre-shared key is usually used for Personal authentication. Personal mode requires only an access point and client on the network. Similarly, you need to type a mixture of numbers and letters in the Pre-shared key [WPA] section of this menu. You may input either 8-63 ASCII characters or 64 HEX characters. Choose WPA2-PSK if needed from Authentication Mode.

-31-WPA2: WPA2 provides a stronger encryption mechanism than WPA. WPA2 is the second generation of WPA security, providing personal and enterprise users with a high level of assurance that only authorized users can access to their wireless network. There is no difference between WPA and WPA2. The only difference is that WPA2 provides a stronger data encryption via the AES, contrast to WPA, which uses Temporal Key Integrity Protocol (TKIP). Choose WPA2 if needed from Authentication Mode.

-32-Once you choose your Authentication Mode, you then need to select the Encryption Mode. For Encryption Mode WEP: Specify the encryption keys. There are two methods to set the WEP keys, as described below: Key will be generated automatically for data private To create encryption keys automatically, click the Key will be generated automatically for data private check box. Note: This function is used in IEEE802.1X Authentication mode. Keys are dynamically generated and distributed by the authentication server. Actually, you can obtain keys by asking your service provider for further configuration and information to gain access to the wireless network.

-33-Pre-configured key [WEP] You can also create encryption keys manually by pulling down the Key Length menu and select either 64bit or 128bit encryption method in the Pre-configured key section of this menu. For 64bit encryption you may choose:  Alphanumeric: entering 5 characters (case sensitive) ranging from “a-z”, “A-Z” and “0-9” (e.g. MyKey).  Hexadecimal: entering 10 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (e.g. 11AA22BB33, showed as below). For 128bit encryption you may choose:  Alphanumeric: entering 13 characters (case sensitive) ranging from “a-z”, “A-Z” and “0-9” (e.g. MyKey12345678).  Hexadecimal: entering 26 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (e.g. 00112233445566778899AABBCC). After you type, the utility uses an algorithm to generate 4 keys automatically. The Key index field allows you specify which of the four keys you use to transmit data on your wireless LAN. You can change the default key by clicking on the up or down arrow and make sure the default key is set up exactly the same on the Wireless LAN stations as they are on the wireless Access Points. After entering the WEP keys in the key field, click the OK button to make the setting take effect. TKIP: A greatly enhanced wireless encryption scheme. Designed to enhance protection by most popular WPA-capable devices. When TKIP is enabled, the key value will be generated automatically for data private. AES: A sophisticated wireless encryption scheme. Designed to increase the strength and complexity of wireless encryption. When AES is enabled, the key value will be generated automatically for data private. If the Security you are configuring requires authentication, simply go to the IEEE802.1X Authentication section of this menu to choose an EAP type.

-34-Certification Tab After you select the EAP type, you need to click Certification Tab to make advanced setting. The following describes configuration of each available EAP type. TLS: Clicking the Certification tab for TLS shows the following menu. Figure 4.1 Figure 4.2 TLS requires the entry of Certificate Information and Login Information for mutual authentication.
