| WPA (Wi-Fi Protected Access) is a means of securing Wi-Fi networks. Wi-Fi is an improvement on the WEP system as it changes the encryption/decryption keys used at the beginning and end of data transfer so that a user cannot make up their own to match the network and gain access. User authorition is also more complex with not only the MAC address being verified but several other aspects and this makes it much more difficult for an unauthorised computer accessing the network. |
