IEEE 802.1X is an IEEE Standard for port-based network access control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.
The Lightweight Extensible Authentication Protocol (LEAP) method was developed by Cisco Systems prior to the IEEE ratification of the 802.11i security standard. [3] Cisco distributed the protocol through the CCX (Cisco Certified Extensions) as part of getting 802.1X and dynamic WEP adoption into the industry in the absence of a standard.
A supplicant, in some contexts, refers to a user or to a client in a network environment seeking to access network resources secured by the IEEE 802.1X authentication mechanism. But saying "user" or "client" overgeneralizes; in reality, the interaction takes place through a personal computer , an Internet Protocol (IP) phone, or similar network ...
A basic form of NAC is the 802.1X standard. Network access control aims to do exactly what the name implies—control access to a network with policies, including pre-admission endpoint security policy checks and post-admission controls over where users and devices can go on a network and what they can do.
Remote Authentication Dial-In User Service (RADIUS) is a networking protocol that provides centralized ... IEEE 802.1X RADIUS Usage Guidelines: September 2003:
EAP was originally developed for PPP(Point-to-Point Protocol) but today is widely used in IEEE 802.3, IEEE 802.11(WiFi) or IEEE 802.16 as a part of IEEE 802.1x authentication framework. The latest version is standardized in RFC 5247.

MS-CHAP is used as one authentication option in Microsoft's implementation of the PPTP protocol for virtual private networks.It is also used as an authentication option with RADIUS [2] servers which are used with IEEE 802.1X (e.g., WiFi security using the WPA-Enterprise protocol).
