An Intrusion Detection Method Based on Symmetric Federated Deep Learning in Complex Networks

Abstract

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.
