Shared Key Authentication requires that the station and the access point have the same WEP 
Key to authenticate. These two authentication procedures are described below.

The following steps occur when two devices use Open System Authentication:

1.

The station sends an authentication request to the access point.

2.

The access point authenticates the station.

3.

The station associates with the access point and joins the network.

This process is illustrated in below.

The following steps occur when two devices use Shared Key Authentication:

1.

The station sends an authentication request to the access point.

2.

The access point sends challenge text to the station.

3.

The station uses its configured 64-bit or 128-bit default key to encrypt the challenge text, and 
sends the encrypted text to the access point.

4.

The access point decrypts the encrypted text using its configured WEP Key that corresponds 
to the station’s default key. The access point compares the decrypted text with the original 
challenge text. If the decrypted text matches the original challenge text, then the access point 
and the station share the same WEP Key and the access point authenticates the station. 

5.

The station connects to the network.
