TTLS (EAP-Tunneled TLS)
This protocol provides authentication like EAP-TLS (see page 141) but
does not require user certificates. User authentication is done using a pass-
word or other credentials that are transported in a securely encrypted “tun-
nel” established using server certificates.
EAP-TTLS works by creating a secure, encrypted tunnel through which
you present your credentials to the authentication server. Thus, inside EAP-
TTLS there is another inner authentication protocol that you must configure
via Additional TTLS Settings.
Use “TTLS” to configure EAP-TTLS as an authentication protocol, select
“Open,” “WPA,” “WPA2,” or “Network EAP” as an association mode.
1 Set 8021x Security as “TTLS,” then choose one of the following:
•Set Association to “Open.” (default configuration)
•Set Association to “WPA.”
•Set Association to “WPA2” and Encryption to either “TKIP” or
“AES.”
•Set Association to “Network EAP” and Encryption to either “WEP”
or “CKIP.”
2 Enter your unique Username to use this protocol.
3 Select Prompt for password to have the user enter this password each
time to access the protocol, or leave Use following password as selected
and enter your unique password to use the protocol without entering a
password each time you use your CN3 Computer.
4 Tap Get Certificates to obtain or import server certificates (see
page 144).
