Network access security for the internet: protocol for carrying authentication for network access

Abstract

Network access authentication is a key procedure for network operators to control user access to the network service. The IETFs recently finished its major work in this area by standardizing an IP-based protocol named Protocol for Carrying Authentication for Network Access (PANA). We provide a comprehensive survey of PANA based on developed IETF standards, and describe its applicability to both existing and emerging network environments.
