802.1X authentication helps enhance the security of 802.11 wireless networks and wired Ethernet networks by requiring the availability of certificates or smart cards for network access. This authentication type is typically used for workplace connections.

802.1X Protocol Introduction:
802.1X protocol originated from the 802.11 protocol, the latter is the IEEE Wireless LAN protocol, the original purpose of the 802.1X protocol is to solve the wireless LAN user access authentication problem. 802.1X is a port-based authentication protocol, which is a method and strategy for authenticating users. The port can be a physical port (such as a wired network card port on a machine or a wireless port), or it can be a logical port (such as a VLAN). For a wireless LAN, a port is a channel. The ultimate goal of 802.1x authentication is to determine whether a port is available. For a port, if the authentication succeeds then "open" the port, allow all messages to pass, if the authentication is unsuccessful to keep the port "off", that is, only allow 802.1X authentication protocol message to pass.
