基于RF位的多阶段动态路径标识模型

RF-bit Based Multi-stage Dynamic Path Identification Model

为防御因特网的分布式拒绝服务攻击,提出了一种新颖的基于RF位的动态路径标识方案(RFPi),并采用多阶段的学习过滤模型.理论分析和仿真实验均表明:所采用的新方案最大程度地实现对标记域的有效利用,提高了攻击包和合法包的区分效果,且具有良好的可扩展性,防御效果较为理想.

To defend against Distributed Denial of Service （DDoS） attacks, a novel dynamic path identification scheme based on RF-bit is presented, featuring in a multi-stage learning and filter model adopted. Theoretical analysis and simulation show that, the presented scheme achieves the most efficient utilization of the identification field, improves the competence for discerning malicious and legitimate packets, and has superior defensibility to the previous schemes.
