[. . . ] Shared ­ Only wireless stations using a shared key (WEP Key identified) are allowed to connect to each other. WPA-PSK ­It is a special mode designed for home and small business users who do not have access to network authentication servers. 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. Note that this option is only available to Windows XP. 10 Parameter Encryption Mode Description None ­ Disable 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. The WEP keys are used to encrypt data transmitted in the wireless network. Select the default encryption key from Key 1 to Key 4 by selecting the radio button. 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. 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". WEP Key (Key1 ~ Key4) 11 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 (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. A pre-shared key is a password that each wireless station uses to access the network. To enable the WPA function in Windows XP, the following software systems are required: 1. Windows XP Service Pack 1 with Windows XP Support Patch for Wi-Fi Protected Access program in addition. Configure the card by Wireless built-in utility (Wireless Zero Configuration). [. . . ] Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers. What is BSS ID A specific Ad hoc LAN is called a Basic Service Set (BSS). What is WEP WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802 . 11 standard. TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security, especially the reuse of encryption keys. [. . . ]
