摘要： DHCP(动态主机配置协议)为用户上网提供了极大的方便性及有效性,但是无论对客户端还是服务器来说,DHCP本身并没有权限控制机制,恶意用户便可以很容易地获得IP访问内部或外部网络。虽然现在也有一些方法来进行用户权限控制,但始终存在缺陷。该文提出一种综合的、相对安全的DHCP系统,介绍了其功能、原理以及实现技术。

Abstract: DHCP(dynamic host configuration protocol) provides great convenience and availability for users.But the DHCP doesn't have an access control mechanism between client and server. Illegitimate users can easily get an IP address and abuse inside and outside network. Although there are some ways to control users' access, there are still some leaks. This paper proposes an all-around and relatively method to resolve the secure problem of the DHCP system, introduces the function, principle and implementing technology.
