EAP

Extensible Authentication Protocol (EAP) is an authentication framework that is used to authenticate dial-up or VPN connections. When a user wants to access a wireless network, the access point requests authentication information from the user, and the received response is sent to the authentication server. Extensible Authentication Protocol (EAP) can be used for such communications.

EAP can run over the data link layer and provides support for duplicate packet elimination and retransmission. EAP is considered as a framework that transports authentication protocols. It supports various authentication methods such as MD5 Challenge, GTC, EAP-TLS, EAP-TTLS, PEAP, etc.

How does EAP work? In this article, we would discuss that in detail.
