Abstract ：
SDN是一种被广泛应用的网络范式.面对DDoS攻击等网络安全威胁,在SDN中集成高效的DDoS攻击检测方法尤为重要.由于SDN集中控制的特性,集中式DDoS攻击检测方法在SDN环境中存在较高的安全风险,使得SDN的控制平面安全性受到了巨大挑战.此外,SDN环境中流量数据不断增加,导致复杂流量特征的更复杂化、不同实体之间严重的Non-IID分布等问题.这些问题对现有的基于联邦学习的检测模型准确性与鲁棒性的进一步提高造成严重阻碍.针对上述问题,本文提出了一种基于联邦增量学习的SDN环境下DDoS攻击检测模型.首先,为解决集中式DDoS攻击检测的安全风险与数据增量带来的Non-IID分布问题,本文提出了一种基于联邦增量学习的加权聚合算法,使用动态调整聚合权重的方式个性化适应不同子数据集增量情况,提高增量聚合效率.其次,针对SDN环境中复杂的流量特征,本文设计了一种基于LSTM的DDoS攻击检测方法,通过统计SDN环境中流量数据的时序特征,提取并学习数据的时序关特征的相关性,实现对流量特征数据的实时检测.最后,本文结合SDN集中管控特点,实现了SDN环境下的DDoS实时防御决策,根据DDoS攻击检测结果与网络实体信息,实现流规则实时下发,达到有效阻断DDoS攻击流量、保护拓扑重要实体并维护拓扑流量稳定的效果.本文将提出的模型在增量式DDoS攻击检测任务上与FedAvg、FA-FedAvg和FIL-IIoT三种方法进行性能对比实验.实验结果表明,本文提出方法相比于其他方法,在DDoS攻击检测准确率上提升5.06%～12.62%,F1-Score提升0.0565～0.1410.

Abstract ：
With the growing diversity of data sources, multi-view learning methods have attracted considerable attention. Among these, by modeling the multi-view data as multi-view graphs, multi-view Graph Neural Networks (GNNs) have shown encouraging performance on various multi-view learning tasks. The message passing is the critical mechanism empowering GNNs with superior capacity to process complex graph data. However, most multi-view GNNs are designed on the well-established overall framework, overlooking the intrinsic challenges of the message passing on multi-view scenarios. To clarify this, we first revisit the message passing mechanism from a Laplacian smoothing perspective, revealing the key to designing a multi-view message passing. Following the analysis, in this paper, we propose an enhanced GNN framework termed Confluent Graph Neural Networks (CGNN), with Cross-view Confulent Message Pssing (CCMP) tailored for multi-view learning. Inspired by the optimization of an improved multi-view Laplacian smoothing problem, CCMP contains three sub-modules that enable the interaction between graph structures and consistent representations, which makes it aware of consistency and complementarity information across views. Extensive experiments on four types of data including multi-modality data demonstrate that our proposed model exhibits superior effectiveness and robustness.

Abstract ：
Multimodal learning mines and analyzes multimodal data in reality to better understand and appreciate the world around people. However, how to exploit this rich multimodal data without violating user privacy is a key issue. Federated learning is a privacy-conscious alternative to centralized machine learning, therefore many researchers have combined federated learning with multimodal learning to break down data barriers for the purpose of jointly leveraging multiple modal data from different clients for modeling. In order to provide a systematic summarize of multimodal federated learning, this paper describes the basic mode of multimodal federated learning, multimodal fusion based on federated learning, multimodal federated learning optimization and multimodal federated learning application, and introduces each type of multimodal federated learning methods in detail. Finally, the future research trends of multimodal federated learning are discussed and analyzed, mainly including the optimization of multimodal federated learning, privacy-preserving techniques for multimodal federated learning, multimodal federated few-shot learning & multimodal federated semi-supervised learning, and data and knowledge-driven multimodal federated learning. © 2024 Elsevier B.V.

Abstract ：
Dangerous driving behavior detection is one of the most important researches in Intelligent Transportation System (ITS), which can effectively reduce the probability and number of traffic accidents. Although some recent approaches combined with deep learning techniques have been proposed for detecting dangerous driving behaviors, the protection of user's privacy is neglected. Therefore, we propose a Federated Deep Attention Fusion model (FedDAF) to address the dual security issues in dangerous driving behavior detection, i.e., data security and traffic security. On the Client side, we design the Deep Attention Fusion Network for extracting and learning driving process features as well as fusing the environmental factors of the vehicle in driving. On the Server side, the Singular Spectrum Entropy Aggregation method is designed to aggregate Clients with high relevance and multiple information content, thereby realizing safety information sharing among Clients. Finally, the experimental results on real datasets show that the FedDAF method has the best performance on several evaluation metrics relative to the existing two categories of benchmark methods. © 2024 Elsevier B.V.

Abstract ：
Recently, dual-target cross-domain recommendation (DTCDR) has been proposed to alleviate the data sparsity problem by sharing the common knowledge across domains simultaneously. However, existing methods often assume that personal data containing abundant identifiable information can be directly accessed, which results in a controversial privacy leakage problem of DTCDR. To this end, we introduce the P2DTR framework, a novel approach in DTCDR while protecting private user information. Specifically, we first design a novel inter-client knowledge extraction mechanism, which exploits the private set intersection algorithm and prototype-based federated learning to enable collaboratively modeling among multiple users and a server. Furthermore, to improve the recommendation performance based on the extracted common knowledge across domains, we proposed an intra-client enhanced recommendation, consisting of a constrained dominant set (CDS) propagation mechanism and dual-recommendation module. Extensive experiments on real-world datasets validate that our proposed P2DTR framework achieves superior utility under a privacy-preserving guarantee on both domains.

Abstract ：
As deep learning has continuously made breakthroughs in computer vision, Image Forgery Localization (IFL) task has also started using deep learning frameworks. Currently, most deep learning-based IFL methods use binary cross entropy as the loss function during model training. However, the number of tampered pixels in image forgery is significantly smaller than the number of real pixels. This disparity makes it easier for the model to classify samples as real pixels during training, leading to a reduced F1 score. Therefore, in this paper, we have proposed a loss function for the IFL task: Forgery Loss. The Forgery Loss assigns weight to the classification loss of tampered pixels and edges, enhances tampered pixel constraints in the model, and amplifies the importance of difficult-to-classify samples. These enhancements facilitate the model to acquire more productive information. Consequently, the F1 score of the model is enhanced. Additionally, we designed an end-to-end, pixel-level detection network DSSE-Net. It comprises of a dual-stream codec network that extracts high-level and low-level features of images, and an edge attention stream. The edge attention stream have a Edge Attention Model which enhances the network's attention to the high frequency edges of the image and, in conjunction with the edge enhancement algorithm in Forgery Loss, improves the model's ability to detect tampered edges. Experiments demonstrate that Forgery Loss can effectively improve the F1 score, while the DSSE-Net accuracy outperforms the current SOTA algorithm.
