摘要
针对RDDoS攻击溯源问题,在包标记技术的基础上,提出了一种自适应的标记算法。通过动态调整标记概率,较好地解决了算法收敛速度和路由器负载问题,并针对传统包标记算法只能对DDoS攻击进行溯源的问题,设计了一种反射标记算法,使包标记技术能应用于RDDoS攻击溯源,最后对算法进行了理论分析及模拟研究,通过与经典包标记算法和动态包标记算法进行对比,验证了其良好的性能。
Aiming at the source tracing of RDDoS attack, a self-adaptive algorithm based on package- marking technology is proposed. By dynamically adjusting marking probability, convergence speed of the algorithm and payload of the router are fairly solved. Traditional packet-marking algorithm can only trace the source of DDoS attacks, and in light of this, a reflective marker algorithm is proposed and designed, thus enabling the package-marking technique to be applied in the source tracin~ of RDDoS attack.
