A Zero‑Sum Game‑Theoretic Analysis for Cost‑Aware Backdoor Attacks and Defenses in Deep Learning
Backdoor attacks pose a critical and increasingly realistic security threat to deep neural networks (DNNs), enabling adversaries to implant hidden behaviors that remain dormant under normal conditions while preserving high performance on benign data. Although numerous defenses have been proposed, most works treat the interaction between attackers and defenders in isolation, without a principled...
