一种基于用户地址的单点认证方法

摘要

In the telecom carder-grade NAT（CGN）enviromnent,the user ADSL dial-up is successful,no longer get public IPv4 addresses,but access to a private IPv4 address.This private address and did not like the public address uniquely identifies the user, therefore,need to consider other ways to achieve the original functionality.In this paper, based on IPv6 addresses to identify users,to achieve a single point NAT444 environment certification.%在电信运营商级别的NAT（CGN）环境下，用户ADSL拨号成功后，不再获得公有IPv4地址，而是获得一个私有IPv4地址。此私有地址并不能像公有地址那样唯一标识用户，因此，需要考虑用其他的方法来实现原有功能。本文提出基于IPv6地址来标识用户，实现在NAT444环境下的单点认证。
