• WEP/WEP Key An encryption method employed by IEEE 802.11. Shared security key used to encrypt and decrypt data sent over wireless networks. This printer supports key length of 64 bits or 128 bits, key format of ASCII code or Hexadecimal, and key number of 1 to 4. • Wi-Fi International association that certifies interoperability of wireless LAN products based on the IEEE 802.11 specification. This machine is a Wi-Fi authorized product. • Wireless LAN A network that, instead of being connected by physical wires, is connected by a wireless technology, such as Wi-Fi. • Wireless Router A wireless transceiver or base station that receives information from wireless clients/the machine and rebroadcasts it. Required in an infrastructure network. • WPA Security framework announced by the Wi-Fi Alliance in October 2002. The security has been strengthened more than WEP. ◦ Authentication WPA defines the following authentication methods: PSK that can be used without an authentication server, plus WPA-802.1x that do require an authentication server. This machine supports WPA-PSK. ◦ Passphrase This encrypted key is used to perform WPA-PSK authentication. The passphrase should be a string of 8 to 63 alphanumeric characters or a 64-digit hexadecimal value. • WPA2 Security framework released by the Wi-Fi Alliance in September 2004 as a later version of WPA. Provides a stronger encryption mechanism through Advanced Encryption Standard (AES). ◦ Authentication WPA2 defines the following authentication methods: PSK that can be used without an authentication server, plus WPA2-802.1x that do require an authentication server. This machine supports WPA2-PSK. ◦ Passphrase This encrypted key is used to perform WPA2-PSK authentication. The passphrase should be a string of 8 to 63 alphanumeric characters or a 64-digit hexadecimal value. • WPS (Wi-Fi Protected Setup) WPS is a standard for easy and secure establishment of a wireless network. There are 2 primary methods used in the Wi-Fi Protected Setup: 356
