摘　　要：为了克服分布式拒绝服务(Distributed Denial of Service,DDo S)攻击效果评估指标体系方法中传统主、客观赋权法的不足,同时提高利用指标体系评估的准确度,文章利用集成学习的思想,将主观赋权法中的模糊层次分析法(Fuzzy-Analytic Hierarchy Process,FAHP)和客观赋权法中的熵权法集成以确定指标权重,将逼近于理想解的排序方法 (Technique for Order Preference by Similarity to an Ideal Solution,TOPSIS)和灰色关联度分析法(Grey Relational Analysis,GRA)集成进行评估计算,提出一种新的评估模型——TOPSIS-GRA集成评估法。同时,针对DDo S攻击效果评估研究不成熟的现状,文章从指标体系、组合赋权、TOPSIS-GRA集成评估法3方面给出了完整可行的评估过程。仿真实验结果表明,文章提出的TOPSIS-GRA集成评估法对DDo S攻击效果评估具有较强的适用性,评估结果客观可靠。In order to overcome the disadvantages o f traditional subjective and objective weighting methods in index system o f distributed denial o f service (DDoS) attack effect evaluation and improve the assessment accuracy, this paper proposes a new integrated evaluation method called TOPSISGRA based on the idea o f ensemble learning, in which fuzzy-analytic hierarchy process (FAHP) iscombined w ith entropy weight method to calculate the index weight, and technique for order preferenceby sim ilarity to ideal solution (TOPSIS) is integrated w ith grey relational analysis (GRA) model toperform the evaluation calculation. W ith the imm aturity research o f DDoS attack effect evaluation, this paper proposes a complete feasible evaluation process including index system, combination weighting and TOPSIS-GRA integrated evaluation method. Experimental results show that the TOPSIS-GRA integrated evaluation method has strong applicability fo r DDoS attack effect assessment, and the evaluation result is objective and reliable.
