WEP
WEP (Wired Equivalent Privacy) is an encryption method according to
IEEE 802.11 on the basis of the RC4 encryption algorithm. WEP offers
mechanisms for data encryption and authentication. WEP uses a key
to encrypt the entire communication. As for encrypted access points,
the same WEP key must be used for the access point and the print
server.
Some access points convert WEP keys that are entered as ASCII text
into arbitrary hexadecimal values. In this case, the WEP keys for the
access point and the print server do not match. It is therefore
recommended to use hexadecimal WEP keys.
WPA /WPA2
In contrast to WEP, WPA (Wi-Fi Protected Access) offers enhanced
mechanisms for exchanging keys. The exchange key is only used at
the beginning of a session. Afterwards a session key is used. The key
is regenerated periodically. The WPA mechanism requires an
authentication at the beginning of a connection.
In the ’Personal Mode’ authentication is done via the Pre Shared Key
(PSK). The PSK is a password with 8-63 alphanumerical characters.
The ’Enterprise Mode’ uses the EAP authentication method.
An individual 128 bit key is used for data encryption after the
authentication. The following two encryption methods can be
distinguished:
• TKIP (Temporal Key Integrity Protocol) for WPA
• AES (Advanced Encryption Standard) for WPA2
Authentication
You can check the identity of a device or user by means of an
authentication method before they gain access to resources in the
network. The print server offers different variants of EAP (Extensible
Authentication Protocol) as authentication method. For further
information; see: ’Print Server Network Authentication’
