摘要:

O-RAN是一种新型的、开放的、自适应的、智能的RAN架构。受人工智能在其他领域取得成功的启发,O-RAN致力于利用机器学习(ML)在流量引导、体验质量预测和异常检测等多种用例中自动有效地管理网络资源。不幸的是,已经表明基于ML的系统容易受到被称为对抗性机器学习(AML)的攻击技术的攻击。这种特殊类型的攻击已经在最近的研究和多个领域得到了证明。在本文中,我们提出了一个系统的AML威胁分析O-RAN。我们首先回顾相关的ML用例,并分析O-RAN中不同的ML工作流部署场景。然后,我们定义了威胁模型,识别了潜在的对手,列举了他们的对抗能力,并分析了他们的主要目标。接下来,我们将探讨与O-RAN相关的各种AML威胁,并回顾可以执行以实现这些威胁的大量攻击,并演示对流量导向模型的AML攻击。此外,我们还分析并提出了各种AML对策,以减轻已识别的威胁。最后,基于识别的AML威胁和对策,我们提出了一种方法和工具,用于在O-RAN中针对特定ML用例执行AML攻击的风险评估。

英文摘要:

O-RAN is a new, open, adaptive, and intelligent RAN architecture. Motivated by the success of artificial intelligence in other domains, O-RAN strives to leverage machine learning (ML) to automatically and efficiently manage network resources in diverse use cases such as traffic steering, quality of experience prediction, and anomaly detection. Unfortunately, it has been shown that ML-based systems are vulnerable to an attack technique referred to as adversarial machine learning (AML). This special kind of attack has already been demonstrated in recent studies and in multiple domains. In this paper, we present a systematic AML threat analysis for O-RAN. We start by reviewing relevant ML use cases and analyzing the different ML workflow deployment scenarios in O-RAN. Then, we define the threat model, identifying potential adversaries, enumerating their adversarial capabilities, and analyzing their main goals. Next, we explore the various AML threats associated with O-RAN and review a large number of attacks that can be performed to realize these threats and demonstrate an AML attack on a traffic steering model. In addition, we analyze and propose various AML countermeasures for mitigating the identified threats. Finally, based on the identified AML threats and countermeasures, we present a methodology and a tool for performing risk assessment for AML attacks for a specific ML use case in O-RAN.
