Tide: Intra- and Inter-Timeslot Enhanced Node Embedding for Probing Attack Detection in SDN

Longyan Ran, Yunhe Cui, Guowei Shen, Chun Guo et autres

Probing the configurations of the Software-Defined Networking (SDN) switches is the essential preliminary for attacking SDN. This study points out a critical bottleneck in detecting probing attack: the dynamically changing character of different kinds of probing attacks makes the existing detection methods …

Mitigating the impact of activation smoothing on weights: A channel permutation and smoothing-based LLMs quantization method

Yanyao Guan, Yunhe Cui, Langtao Zhao, Guowei Shen et autres

Quantization has emerged as an effective technique to reduce the memory requirement of Large Language Models (LLMs). However, we observed that activation smoothing destroys the original flat distribution of weights and existing methods struggle to smooth activation outliers with extremely large magnitudes, …

FedC 3 : Federated Covert Communication Construction Via Unlearning-Based Decision Boundary Manipulation

Yuan Ping, Y Zhang, Wenhong Wu, Chun Guo et autres

Federated learning (FL) has been widely employed in sensitive data analysis for various domains such as healthcare and finance. Given growing concerns about privacy, federated unlearning (FU) has also been introduced to support users’ right to revoke the use of sensitive data; …

DPA-TA2C: Dynamic Priority-Aware Workflow Scheduling Method with Transformer and A2C in Cloud Data Center

Fashun Jian, Guowei Shen, Xiaodan Lv, Chun Guo et autres

Workflow scheduling in cloud data centers faces challenges such as task dependencies, resource heterogeneity, and dynamic workloads. Heuristic and meta-heuristic algorithms lack environment awareness and fail to meet real-time scheduling requirements. Existing deep reinforcement learning algorithms exhibit specific environment-aware capabilities; however, their …

Patrol: Max-Min Passive-Active Hybrid in-Band Network Telemetry Method in SDN

Yang Cao, Yunhe Cui, Hongfeng Gao, Chun Guo et autres

With the growing scale and complexity of networks, the need for real-time and fine-grained network monitoring is becoming increasingly critical. In this work, we propose a new insight into current In-band Network Telemetry (INT) approaches, which collects as much telemetry metadata by …

Abnormal electricity data identification algorithm based on SPDMD model in data platform

Chun Guo, Caixia Zhang, Shan He, Zijian Pan et autres

Actual measured electricity data is prone to falling into false modes, reducing the contribution of dominant modes while limiting the availability of historical feasible regions, resulting in poor accuracy of typical feature extraction and high identification time. Therefore, an abnormal electricity data …

Towards saturation attack detection in SDN: a multi-edge representation learning-based method

Zhigang Ji, Yunhe Cui, Guowei Shen, Yi Chen et autres

Saturation attack detection in Software-Defined Networking (SDN) focuses on identifying and mitigating flow table overflow attacks on switches and overload attacks on the SDN controller. These attacks can hinder the installation of legitimate flow entries in switches and may even exhaust the …

The DUDFTO Attack: Towards Down-to-UP Timeout Probing and Dynamically Flow Table Overflowing in SDN

Jiasong Li, Yunhe Cui, Yi Chen, Guowei Shen et autres

As a new network structure, the decoupling of the control plane and forwarding plane makes Software-Defined Networking (SDN) widely used in large-scale network scenarios. However, the decoupling network architecture also brings new vulnerabilities. The flow table overflow attack is an attack strategy …
