How does a wireless client authentication occur when I use the 802.1x authentication framework?
A. When the wireless client (EAP client) becomes active, the wireless client authenticates either with open or shared authentication. 802.1x works with open authentication and starts after the client successfully associates to the AP. The client station can associate, but can pass data traffic only after successful 802.1x authentication. Here are the steps in 802.1x authentication: • AP (Authenticator) configured for 802.1x requests the user’s identity from the client. • Clients respond with its identity within a stipulated time period. • Server checks user’s identity and begins authentication with the client if the user’s identity is present in its database. • Server sends a success message to the AP. • Once the client is authenticated, the server forwards the encryption key to the AP which is used to encrypt/decrypt traffic sent to and from the client. • In the step 4, if the user’s identity is not present in the database, the server drops the authentication and sends a failure messa
