[. . . ] Open System ­ No authentication is needed among the wireless network. Shared Key ­ Only wireless stations using a shared key (WEP Key identified) are allowed to connecting 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-PSK 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 difference between WPA-PSK and WPA2-PSK is that WPA2PSK provides data encryption via the AES. WPA 802. 1X ­ WPA provides a scheme of mutual authentication using either IEEE 802. 1x/Extensible Authentication Protocol (EAP) authentication or pre-shared key (PSK) technology. It provides a high level of assurance to enterprises, small businesses and home users that data will remain protected and that only authorized users may access their networks. For enterprises that have already deployed IEEE 802. 1x authentication, WPA offers the advantage of leveraging existing authentication databases and infrastructure. Network Authentication 22 WPA2 802. 1X ­ Like WPA, WPA2 supports IEEE 802. 1x/EAP authentication or PSK technology. It also includes a new advanced encryption mechanism using the Advanced Encryption Standard (AES). The difference between WPA and WPA2 is that WPA2 provides data encryption via the AES. WEP 802. 1X ­ It's a special mode for using IEEE 802. 1x/EAP technology for authentication and WEP keys for 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. It is a text string with a maximum of 32 alphanumeric characters, for example: "Test". This passphrase may not work with other vendors' products due to possible incompatibility with other vendors' passphrase generators. You must use the same passphrase or WEP key settings for all wireless computers within the network. Select one of the four keys to be the data encryption key. Passphrase Key Index (advanced) 23 Parameter Network Key Description The keys are used to encrypt data transmitted in the wireless network. For example: "01234567890123456789abcdef". Confirm Network Key Enter the same network key to confirm. EAP Type GTC ­ GTC is an authentication protocol which allows the exchange of clear text authentication credentials across the network. TLS ­ TLS is the most secure of the EAP protocols but not easy to use. [. . . ] Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers. 36 6. 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. [. . . ]
