Protocol for Carrying Authentication for Network Access (PANA)
Status of This Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
Abstract
This document defines the Protocol for Carrying Authentication for
Network Access (PANA), a network-layer transport for Extensible
Authentication Protocol (EAP) to enable network access authentication
between clients and access networks. In EAP terms, PANA is a
UDP-based EAP lower layer that runs between the EAP peer and the EAP
authenticator.
