基于CXPST攻击算法的BGP协议安全性分析

针对CXPST攻击算法存在的一些不符合网络实际情况的假设条件进行了深入研究和分析,重点对CXPST攻击算法中关键路径的选取策略进行了详细的分析,提出了关键路径选取的改进策略,并结合路由器中路由表内容进行分析,使得开展CXPST攻击算法过程中关键路径的选取更有针对性。仿真测试结果表明,文章研究的攻击算法比原始的CXPST攻击算法和单纯改变关键路径选取策略的攻击算法,都更具有实效性,能够导致网络中的骨干路由器更快的进入崩溃状态。

BGP Protocol Security Analysis Based on the CXPST Algorithm

This paper has deeply research and analysis of some hypothesis in CXPST algorithm which is different in the actual circumstance of network.It ocused on the critical path selection strategy in CXPST algorithm.The critical path selection improvement strategy is put forward,which combined with the router routing table content.It has quick effection in CXPST attack process.The simulation test results show that,compared with the original CXPST algorithm and improved the critical path selection strategy simply,the attack algorithm designed in this paper can drop the network backbone router into collapse more quickly.
