摘 要:DHCP是應用廣泛的IP地址分配技術。由于DHCP的技術特點,它有兩種被廣泛討論的安全風險,一是假冒DHCP服務器攻擊,二是DHCP服務器的餓死攻擊。本文通過分析RFC國際規范和現有的應用技術第一次對DHCP租約時間進行了安全性的討論,并給出了對策措施。

Abstract: DHCP is a widely used IP address allocation technique, and it has two security risks due to its technical property. One is unauthorized DHCP servers providing false information to clients, and another is resource exhaustion attacks from malicious DHCP clients. This paper discusses the security issues induced by DHCP lease time in some application environment and gives the corresponding countermeasures in the end.
Key words: Dynamic Host Configuration Protocol (DHCP); DHCP client; DHCP server
