摘要
文章详细分析了"黑洞"攻击的基本原理,研究了基于"黑洞"攻击的网络监听方法,给出了中转数据报的详细结构,提出了防御黑洞攻击的两种策略,即采用复杂密码加MD5认证方式和尽量缩小OSPF协议的扩散区域,可以在一定程度上预防"黑洞"攻击。
This article described the network monitor method based on the ＂black hole＂.The structure of datagram had been carefully analyzed. Two defense strategy had been provided. A method used complex passwords and MD5 authentication mode, Reduced diffusion region method was also provided. To a certain extent, these strategies could prevent the ＂black hole＂ attacks.
