802.1x relay: A new model for authentication of nat-enabled router

Abstract

A broadband router with the Network Address Translation (NAT) technology is popular in the private networks. The compatibility with various access authentication mechanisms of public network is a key issue for achieving interconnects between public network and private network. This paper presents a compatible method for the broadband router to support various 802.1x authentication mechanisms. Adopting this method, the broadband router can be authenticated and authorized without a complex program in various authentication scenarios.
