Network authentication: The printer's factory default
setting is 'Open', which does not require security for
authorization or encryption. The other possible values
are 'OpenThenShared', 'Shared', and 'WPA-PSK'
®
(Wi-Fi Protected Access Pre-Shared Key).
• WPA increases the level of over-the-air data
protection and access control on existing and future
Wi-Fi networks. It addresses all known weaknesses
of WEP, the original native security mechanism in
the 802.11 standard.
• WPA2 is the second generation of WPA security;
providing enterprise and consumer Wi-Fi users with
a high level of assurance that only authorized users
can access their wireless networks.
Data encryption:
• Wired Equivalent Privacy (WEP) provides security by
encrypting data sent over radio waves from one
wireless device to another wireless device. Devices
on a WEP-enabled network use WEP keys to encode
data. If your network uses WEP, you must know the
WEP key(s) it uses.
• WPA uses the Temporal Key Integrity Protocol (TKIP)
for encryption and employs 802.1X authentication
with one of the standard Extensible Authentication
Protocol (EAP) types available today.
• WPA2 provides a new, encryption scheme,
the Advanced Encryption Standard (AES). AES is
defined in counter cipher-block chaining mode
(CCM) and supports the Independent Basic Service
Set (IBSS) to enable security between client
workstations operating in ad hoc mode.
