arXiv:2502.01272v3 Announce Type: replace Abstract: Graph Neural Networks (GNNs) have achieved notable success in tasks such as social and transportation networks. However, recent studies have highlighted the vulnerability of GNNs to backdoor attacks, raising significant concerns about their reliability in real-world applications. Despite initial efforts to defend against specific graph backdoor attacks, existing defense methods face two main challenges: either the inability to establish a clear distinction between triggers and clean nodes, resulting in the removal of many clean nodes, or the
This research addresses the growing concern over the vulnerability of AI systems, particularly Graph Neural Networks, to adversarial attacks as their deployment expands into critical real-world applications.
The security and robustness of AI models are paramount for their trustworthy integration into infrastructure and decision-making systems, making defenses against sophisticated attacks a strategic imperative.
This research contributes to improving the resilience of GNNs against backdoor attacks, potentially leading to more secure and reliable AI deployments in areas like social networks and transportation.
