[. . . ] 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 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. The encryption methods are including TKIP and AES. Note that this option is only available for Windows XP. 802. 1x Authentication 802. 1x Setting It allows to get more powerful secure when you enable it and press the 802. 1x setting button, the user can establish the information that authentication is correlated with further through this picture , such as protocol , ID and password , Client evidence or server evidence of Tunnel , etc. , please refer to the following chapter 3. 2. 3 for detail information. Encryption Mode None ­ Disable the WEP Data Encryption. 10 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. Note: All devices in the network should use the same encryption method to ensure the communication. WPA Pre-Shared Key The WPA-PSK key can be from eight to 64 characters and can be letters or numbers. This same key must be used on all of the wireless stations in the network. WEP Key (Key1 ~ Key4) The WEP keys are used to encrypt data transmitted in the wireless network. There are two types of key length: 64-bit and 128-bit. Select the default encryption key from Key 1 to Key 4 by selected the radio button. Fill the text box by following the rules below. 64-bit ­ Input 10-digit Hex values (in the "A-F", "a-f" and "0-9" range) or 5-digit ASCII characters (including "a-z" and "0-9") as the encryption keys. For example: "0123456aef" or "test1". 128-bit ­ Input 26-digit Hex values (in the "A-F", "a-f" and "0-9" range) or 13-digit ASCII characters (including "a-z" and "0-9") as the encryption keys. For example: "01234567890123456789abcdef" or "administrator". 3. 2. 2 Enable WPA in Windows XP Wi-Fi Protected Access (WPA) is a specification of standards-based, interoperable security enhancement that strongly increases the level of data protection (encryption) and access control 11 (authentication) for existing and future wireless LAN systems. The technical components of WPA include Temporal Key Integrity Protocol (TKIP) for dynamic key exchange, and 802. 1x for authentication. There are two types of WPA security: WPA-PSK (no server) and WPA (with server). WPA requires a Radius Server to complete the authentication among wireless stations and Access Points. Typically, this mode is used in a enterprise environment. [. . . ] 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. [. . . ]
