Win8 open 802.1x authentication skills

If your computer is installed with Win8 system, in order to ensure the security of wireless network and wired Ethernet network, now want to open the system's IEEE 802.1X authentication function, but I do not know how to Win8 Enable IEEE 802.1X network authentication function under the system, then you will be sure to read this tutorial.
First, let's spread a little knowledge for everyone. About 802.1x protocol introduction:
802.1x protocol originated from 802.11 protocol, the latter is IEEE wireless LAN protocol. The original intention of formulating 802.1x protocol is to solve wireless LAN users. Access authentication issues. 802.1x is a port-based authentication protocol, which is a method and strategy for authenticating users. A port can be a physical port (such as a wired NIC port on a machine or a wireless port) or 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 if a port is available. For a port, if the authentication is successful, then "open" the port to allow all packets to pass; if the authentication is unsuccessful, keep the port "closed", that is, only 802.1x authentication protocol packets are allowed to pass. .
802.1x authentication helps to enhance the security of 802.11 wireless networks and wired Ethernet networks by requiring certificates or smart cards for network access. This type of authentication is typically used for workplace connections.
