WEP assumed all devices in the network share a secret key. The purpose of the authentication scenario is for the STA to prove that it possesses the secret key. As shown in the figure below, the STA sends a message to AP requesting authentication. The AP issues a challenge, which is a sequence of 128 random bytes sent as plain text. The STA encrypts the challenge with the shared key and returns it to the AP. The AP decrypts the incoming value and compares it to the challenge that it sent. If there is a match, the AP confirms that authentication has succeeded.
