大规模拒绝服务（DDoS）攻击的防御与清洗系统

摘要

Firstly, the selection, representation, analysis and model solution of DDoS attack feature are established. Then, proceeding from this, the DDoS attack defense method based on the variable threshold constraint of sensitive access parameters is also provided. Finally, the DDoS attack traffic cleaning technique based on the variable probability mark is studied.%首先建立DDoS攻击特征的选择、表示、分析以及模型求解。然后，在此基础上研究基于敏感访问参数可变阈值约束的DDoS攻击防御方法。最后，研究基于可变概率标记的DDoS攻击流量清洗技术。
