When attempting to associate with a wireless network, clients search for an in range access point and request to connect. This authentication process takes place prior to joining the network. Any wireless client must first authenticate to the target network and ensure compatibility before being able to join and forward traffic over a given wireless network.
There are two different methods of authentication. They are as follows:
Open System Authentication
Shared Key Authentication
In Open System authentication, there is no verification of the identity of the devices and any wireless client can join the network, assuming it has the required characteristics, such as data transfer rates and a wireless protocol.
In Shared Key authentication, a shared key is used to verify both the access point and the wireless client. The shared key is configured on both devices and validated before the connection is made. During the shared key authentication process, the access point sends...
