TTLS:
Clicking the
Certification
tab for TTLS shows the following menu.
TTLS requires the mutual authentication between station and access points. You must present a
User Name
and
Password
in the User Information field that will be verified by TTLS-capable
server. This mutual authentication ensures that only authorized users are allowed access to the
network.
3.3 Authentication Type
The IEEE 802.11b/g standard describes a simple authentication method between the wireless
stations and AP. Two authentication types are defined:
Open
system mode and a
Shared
key
mode.
z
Open system mode is implemented for ease-of-use and when security is not an issue. It
requires NO authentication, since it allows any device to join a network without performing
any security check. The wireless station and the AP do not share a secret key. Thus the
wireless stations can associate with any AP and listen to any data transmitted plaintext.
z
Shared key mode involves a shared secret key to authenticate the wireless station to the AP. It
requires that the station and the access point use the same WEP key to authenticate. This
basically means that WEP must be enabled and configured on both the AP and the other
wireless stations with a same key. Shows as below:
