How to open 802.1x network authentication in Win8 system?

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.

Introduction to 802.1x Protocol:

The 802.1x protocol originated from the 802.11 protocol, the latter is the IEEE wireless LAN protocol. The original intention of the 802.1x protocol was to solve the problem of access authentication for wireless LAN users. 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. .
