RFC 4851: The Flexible Authentication via Secure Tunneling Extensible Authentication Protocol Method (EAP-FAST), N. Cam-Winget, D. McGrew, J. Salowey, H. Zhou2007-05-01T23:00:00-00:00This 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.
