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.
• 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.
• 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:
