Technical Summary
This document defines an Extensible Authentication Protocol method
called EAP Generalized Pre-Shared Key (EAP-GPSK). This method is a
lightweight shared-key authentication protocol supporting mutual
authentication and key derivation. The method should be able to
support any future EAP channel binding requirements.
Working Group Summary
The base document for EAP-GPSK was originally created by a design
team. There was working group consensus to accept the document to
meet the Pre-Shared-Key EAP method on the working group charter.
Document Quality
There is an existing implementation of the protocol. NIST was
consulted and participated in the review of the document resulting
in some modifications to the key derivation function. The document
has been reviewed by external researchers and their feedback has
been incorporated. EAP experts within the EMU working group have
reviewed the document. This document meets requirements set forth
in RFC 3748, RFC 4017, and RFC 5247.
Personnel
Joe Salowey is the document shepherd. The responsible
Area Director is Pasi Eronen.
