Abstract

The proliferation of open radio access networks (O-RAN) in modern 5G systems has ushered in enhanced flexibility and efficiency, but it has also introduced novel security challenges. In response, this paper presents a novel AI-based anomaly detection framework tailored for O-RAN networks operating in 5G environments. By employing principal component analysis for dimensionality reduction and a deep neural network for classification, the proposed system efficiently processes large-scale 5G traffic data while achieving high detection accuracy and low latency. Experimental evaluation on an open-source testbed with realistic cellular traffic demonstrates rapid convergence, with both training and validation accuracy values approaching 100% and effective detection of anomalies introduced via user equipment identifier swaps. The testbed processed over 300,000 traffic samples with 31 distinct network features, emulating 8 unique user equipment profiles under diverse radio conditions. Under adversarial scenarios, such as identity-swapping attacks, the system identified anomalous behavior with detection rates exceeding 40%, while maintaining a near-zero false positive rate on clean traffic. These results underscore the testbed’s capability to simulate complex 5G environments and the framework’s ability to deliver highly accurate, low-latency, and scalable anomaly detection. Overall, this work highlights the potential of advanced AI techniques to significantly enhance the security and resilience of modern wireless communication networks.
O-RAN实验的开放测试平台,支持ai控制和监控
现代5G系统中开放无线接入网络(O-RAN)的普及带来了更高的灵活性和效率,但也带来了新的安全挑战。为此,本文提出了一种针对5G环境下运行的O-RAN网络量身定制的基于人工智能的新型异常检测框架。该系统通过主成分分析降维和深度神经网络分类,有效处理大规模5G流量数据,同时实现高检测精度和低延迟。在真实蜂窝流量的开源测试平台上进行的实验评估显示了快速收敛,训练和验证精度值接近100%,并且通过用户设备标识符交换有效检测引入的异常。该试验台处理了超过30万个流量样本,具有31种不同的网络特征,在不同的无线电条件下模拟了8种独特的用户设备配置文件。在对抗性场景下,如身份交换攻击,系统识别异常行为的检测率超过40%,同时对正常流量保持接近零的误报率。这些结果强调了测试平台模拟复杂5G环境的能力,以及框架提供高精度、低延迟和可扩展异常检测的能力。总的来说,这项工作突出了先进的人工智能技术在显著增强现代无线通信网络的安全性和弹性方面的潜力。
