针对软件定义网络(SDN)环境中DDoS攻击流量特征复杂、包级语义信息利用不足以及检测模型精度与效率难以兼顾的问题,设计了一种融合有效载荷信息与流级统计特征的混合检测模型。该模型首先基于改进的Mamba网络对有效载荷序列进行深度建模,以挖掘包级特征中的时序依赖与上下文信息;其次,采用Ghost卷积替代常规卷积结构,在保持特征表达能力的同时有效减少模型参数量并提升计算效率;最后,通过自注意力机制对多维融合特征进行加权,以强化关键攻击特征并抑制无关信息。实验结果表明,所设计模型在CICDDoS2019数据集上实现了99.56%的检测准确率,平均检测延迟仅为0.21 ms,优于现有主流方法。此外,在多个公开数据集上的验证结果进一步证明,该模型具有良好的泛化能力。
To address the challenges of complex traffic characteristics
insufficient utilization of packet-level semantic information
and the trade-off between detection accuracy and efficiency in software-defined networking (SDN) environments
a hybrid detection model that integrates payload information and flow-level statistical features was proposed. Specifically
an improved Mamba network was employed to perform deep modeling of payload sequences
enabling the extraction of temporal dependencies and contextual semantics within packet-level features. Meanwhile
the conventional convolutional structure was replaced with Ghost convolution to effectively reduce the number of parameters and computational cost while maintaining strong feature representation capability. Finally
a self-attention mechanism was introduced to adaptively weight and fuse multi-dimensional features
which enhanced the representation of critical attack patterns and suppresses irrelevant information. Experimental results demonstrate that the proposed model achieves a detection accuracy of 99.56% on the CICDDoS2019 dataset with an average detection latency of only 0.21 ms
outperforming existing mainstream methods. Moreover
validation on multiple public datasets further confirms the strong generalization capability of the proposed model.
