Requirements for a
Tunnel-Based Extensible Authentication Protocol (EAP) Method
Abstract
This memo defines the requirements for a tunnel-based Extensible
Authentication Protocol (EAP) Method. This tunnel method will use
Transport Layer Security (TLS) to establish a secure tunnel. The
tunnel will provide support for password authentication, EAP
authentication, and the transport of additional data for other
purposes.
