The Flexible Authentication via Secure Tunneling Extensible Authentication Protocol Method
RFC 4851, “The Flexible Authentication via Secure Tunneling Extensible Authentication Protocol Method”, is an Informational document published in May 2007 by N. Cam-Winget, D. McGrew, J. Salowey, H. Zhou. It has since been updated by RFC 8996, RFC 9427. The canonical text is published by the RFC Editor.
Abstract
This document defines the Extensible Authentication Protocol (EAP) based Flexible Authentication via Secure Tunneling (EAP-FAST) protocol. EAP-FAST is an EAP method that enables secure communication between a peer and a server by using the Transport Layer Security (TLS) to establish a mutually authenticated tunnel. Within the tunnel, Type-Length-Value (TLV) objects are used to convey authentication related data between the peer and the EAP server. This memo provides information for the Internet community.
