Internet Engineering Task Force (IETF) Y. Sheffer Request for Comments: 6124 Independent Category: Informational G. Zorn ISSN: 2070-1721 Network Zen H. Tschofenig Nokia Siemens Networks S. Fluhrer Cisco February 2011 An EAP Authentication Method Based on the Encrypted Key Exchange (EKE) Protocol Abstract The Extensible Authentication Protocol (EAP) describes a framework that allows the use of multiple authentication mechanisms. This document defines an authentication mechanism for EAP called EAP-EKE, based on the Encrypted Key Exchange (EKE) protocol. This method provides mutual authentication through the use of a short, easy to remember password. Compared with other common authentication methods, EAP-EKE is not susceptible to dictionary attacks. Neither does it require the availability of public-key certificates. Status of This Memo This document is not an Internet Standards Track specification; it is published for informational purposes.
