Special Issue Information

Dear Colleagues,

Deep learning networks have been widely applied in real-world engineering problems. Some effective deep learning networks have typical symmetric structures. For example, the encoder and decoder in U-Net networks have symmetry, as well as the generator and discriminator in GANs. Actual engineering problems are usually based on nonlinear data or models. Nonlinear models typically exhibit symmetry, nonconvexity, and multiple equivalent solutions. Symmetry problems involve the deep integration and clever application of mathematical principles, physical laws, and engineering design. By conducting in-depth research and utilizing the symmetry of deep learning networks, more efficient and powerful deep learning models can be designed to achieve better application results in practical engineering applications.

The rapid development of the current 5G/6G network has added tremendous pressure to traditional security detection in the scenario of dealing with large-scale network attacks, resulting in high time complexity and low efficiency of attack identification. According to the deep network and its symmetry principle, this paper proposes a complex network intrusion detection and recognition method based on symmetric federation optimization, named IDS, which aims to reduce the time complexity and improve the accuracy and efficiency of attack identification. By using a symmetric network UNet-based deep feature learning to reconstruct data and construct the input matrix, we optimize the federated deep learning algorithm with a symmetric auto-encoder to make it more suitable for a complex network environment. The experimental results demonstrate that the technology based on the symmetric network proposed in this paper possesses significant advantages in terms of intrusion detection accuracy and effectiveness, which can effectively identify network intrusion and improve the accuracy of current complex network intrusion detection. The proposed symmetric intrusion detection method not only solves the bottleneck of traditional detection methods and improves the training efficiency of the model, but it also provides a new idea and solution for network security research.
