EAP encapsulation over LANs (EAPOL): is the key protocol in IEEE x for key exchange. It allows WLAN clients to communicate with an authentication server
to validate their credentials, and supports strong mutual authentication and key management. There are two main EAPOL-key exchanges defined in IEEE i the way handshake and the group key handshake. Figure 6 below is a diagram depicting the IEEE i protocol structure IEEE i Components
