                                  基于DHCP和Portal的无感知网络安全认证

                                  时间:2018-12-30 09:21作者:阳甫军 刘科 张艺 张
                                  本文导读:这是一篇关于基于DHCP和Portal的无感知网络安全认证的文章,由于目前大多数校园网依旧采用传统的Portal认证方式,用户登录方式较为繁琐,登录后安全性较低,故本文提出一种校园网无感知认证方案。

                                    摘    要: 随着高校信息化的不断发展,校园网络管理员的工作日益繁重,校园网安全显得越来越重要。为简化用户的网络接入认证过程,确保用户登录安全,提出一种基于DHCP与无感知认证相结合的网络安全接入方案。该方法首先依据MAC地址作为用户接入网络的安全标志,以Portal认证方式接入校园网,结合DHCP协议,对认证方式进行改进和二次验证,从理论上论证了方案的可行性。最后通过实际实验的模拟验证,验证了该方法的可行性,实现了用户的无感知安全认证,提高了校园网的安全性。

                                    1、 技术背景

                                    1.1、 DHCP原理概述

                                    DHCPSHIJIYUBOOTPDETUOZHANBANBEN,QIZHUYAOYOULIANGGEBUFENZUCHENG:

                                    (2)KEHUDUAN:SHIYONGFUWUQIFENPEIDEIPHUANJINGSHUJU。

                                    当DHCP服务器与用户进行交互的过程中,DHCP对应的报文中会产生options字段,而options字段里会带有基本参数,除了基础的IP地址等信息外,还会有网关地址、子网掩码等信息,这些字段信息也可以在认证过程中进行验证。
