WEP Encryption
WEP encryption can be used in 2 versions: Open and Shared. In both cases the data is encrypted.
• Open
Everyone can connect to the access point but only if the right encryption key is provided, data can be exchanged. Hence, if you
supply the wrong key you will be authenticated and connected, however, no data frames will be passed through the Access Point
or WLAN ad hoc device. This can be a bit confusing from the users perspective as he sees that the client is connected but
"nothing works".
• Shared
Shared authentication adds a handshake to the authentication process. If the wrong key is used the authentication fails and the
client cannot connect to the Access Point or WLAN ad hoc device. Hence, it is not possible to connect if the wrong WEP key is
supplied.
