Shared: WEP
authentication method. First, the WLAN party sends a request for
authentication to an access point. Hereupon, the access point sends a generated
series of characters. The WLAN party encodes the series of characters with the
entered key and returns the answer to the access point. Hereupon, the access
point should accept the answer and send an authentication code that allows the
