Setting the Encryption Method and the
Authentication Method in Wireless LAN Advanced
Connection Mode
When connecting and communicating in wireless LAN mode, you can
select one of the following encryption and authentication methods.
•WEP
Data is encrypted with a code key (WEP key)
This mechanism prevents communication unless the encrypted keys for
the access point and the projector match.
•WPA
This is an encryption standard that improves security which is a weak
point of WEP. Although there are several kinds of WPA encryption
methods, this projector uses "TKIPg". TKIP uses PSK to automatically
update the encryption key at regular fixed intervals, which makes it
harder to break compared to WEP which uses a constant encryption key.
WPA also includes user authentication functions. WPA authentication
provides two methods: using an authentication server, or authenticating
between a computer and an access point without a server. This projector
supports the latter method, without a server.
•EAP
EAP is a client that uses a protocol to communicate between
authentication servers. There is EAP-TLS which uses electronic
certification for user authentication, LEAP which uses user ID and
password, and EAP-TTLS and so on.
