Internet Engineering Task Force (IETF) Y. Ohba Request for Comments: 5836 Toshiba Category: Informational Q. Wu, Ed. ISSN: 2070-1721 Huawei G. Zorn, Ed. Network Zen April 2010 Extensible Authentication Protocol (EAP) Early Authentication Problem Statement Abstract Extensible Authentication Protocol (EAP) early authentication may be defined as the use of EAP by a mobile device to establish authenticated keying material on a target attachment point prior to its arrival. This document discusses the EAP early authentication problem in detail. Status of This Memo This document is not an Internet Standards Track specification; it is published for informational purposes.
