Besides that, there are other typical LAN security mechanisms to ensure privacy, such as: password protection, end-to-end encryption, virtual private networks, and authentication. WPA2, the second generation of WPA, provides stronger data protection and network access control and is also designed to secure all versions of 802.11 devices, including 802.11b, 802.11a, 802.11g, and 802.11n standards, multi-band and multi-mode. In addition, based on the ratified IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1X-based authentication. WPA2 is backward compatible with WPA. Using Your VAIO Computer > Using the Wireless LAN n 58 N Starting Wireless LAN Communications You first need to establish wireless LAN communications between your computer and an access point (not supplied). See Windows Help and Support for more information. ! For details on how to select the channel that will be used by the access point, see the manual that came with your access point. To start wireless LAN communications Turn on the WIRELESS switch. Make sure the WIRELESS indicator light turns on. . For WPA-PSK or WPA2-PSK authentication, you must enter a passphrase. The passphrase is case sensitive and must be a text string between 8 and 63 characters in length or a hexadecimal string of 64 characters. Using Your VAIO Computer > Using the Wireless LAN n 59 N Stopping Wireless LAN Communications To stop wireless LAN communications Turn off the WIRELESS switch. Make sure the WIRELESS indicator light turns off. ! Turning off the wireless LAN function while accessing remote documents, files, or resources may result in data loss. Using Your VAIO Computer > Using the Bluetooth Function n 60 N Using the Bluetooth Function Some features and options in this section may not be available on your computer. See the specifications to find out about the configuration of your computer. You can establish wireless communications between your computer and other Bluetooth® devices such as another computer or a mobile phone. You can transfer data between these devices without cables at a range of up to 10 meters in an open area. Bluetooth Security The Bluetooth wireless technology has an authentication function, which allows you to determine with whom you choose to communicate. With the authentication function, you can prevent any anonymous Bluetooth devices from accessing your computer. The first time two Bluetooth devices communicate, a common passkey (a password required for authentication) should be determined for both devices to be registered. Once a device is registered, there is no need to re-enter the passkey. . The passkey can be different each time, but must be the same at both ends. For certain devices, such as a mouse, no passkey can be entered. Using Your VAIO Computer > Using the Bluetooth Function n 6...
