论DHCP网络协议的安全性问题与解决

DHCP技术可以有效地解决目前IP地址资源不足和无线网络用户的移动性,并极大地减轻大型网络管理员的工作量,有利于快速地搭建一个大型网络或修改其网络配置。但由于DHCP协议在设计时未考虑安全的因素,在使用DHCP服务器为主机配置网络地址和参数的网络中面临着很多DHCP威胁,所以对DHCP安全性的研究具有重大意义。该文笔者即围绕DHCP网络协议的安全性问题展开集中讨论研究,包括归纳DHCP网络安全的主要威胁、提出了消除威胁的策略建议、用对比的方式挖掘减少威胁的方法以及安全实现。

On the DHCP Network Protocol Security Problems and Solutions

DHCP technology can effectively solve the problem of lack of IP address resource and mobile wireless network. It greatly reduce the workload of large-scale network administrator,and help to build a large network quickly or modify their network configuration. How-ever,because of DHCP protocol does not take into account the design of safety factors,in the use of DHCP server configuration for the host network address and network parameters are faced with the thread of DHCP. So the research of the safety of DHC...
