The correct sequence of steps involved in establishing a network connection using the shared key

authentication process is 4 -> 1 -> 3 -> 5 -> 2. This is based on the following description of the shared

key authentication process from the Network Defense Essentials courseware:

The station sends an authentication frame to the AP, indicating that it wants to use shared key

authentication.

The AP responds with an authentication frame containing a challenge text, which is a random string

of bits.

The station encrypts the challenge text using its configured WEP key, which is derived from the

shared secret key (password) that is also known by the AP. The station sends the encrypted text back

to the AP in another authentication frame.

The AP decrypts the encrypted text using its configured WEP key and compares it with the original

challenge text. If they match, the AP sends a positive authentication response to the station. If they

do not match, the AP sends a negative authentication response to the station.

The station connects to the network if the authentication is successful.
