Question

Differentiate the core elements of PPP and EAP protocol.

Answer 1

PPP:

It was originally a protocol for connecting and authenticating dialup modems. PPP stands for Point-to-Point Protocol. PPP is a layer 2 communication protocol used to connect two endpoints and authenticate using a username and password. Today's PPP is usually encased in an Ethernet frame and operates over Ethernet (PPPoE) as PPP over Ethernet. One way to prevent unauthorized people from "dialing" into our computers was the point-to-point protocol. PPPoE is commonly used for cable modems or for Internet connections to DSL connections to ISPs. PPP includes two authentication mechanisms: Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP).

EAP:

It is an authentication protocol framework that original PAP and work within the PPP to provide support for authentication protocols beyond the CHAP protocol. EAP stands for Extensible Authentication Protocol. EAP protocol method is a series of interface known as EAP. Supports a wide range of EAP Kerberos, passwords, host certificates, and authentication mechanisms, including public-key authentication, as well as hardware products such as authentication dongles, smart cards, and USB tokens. EAP provides several options for authentication and is mainly used on wireless networks.
