Adversarial Machine Learning for Secure and Explainable AI Systems: A Comprehensive Review

Adversarial machine learning (AML), reinforcement learning (RL), and explainable artificial intelligence (XAI) are increasingly studied as separate problems, yet their interactions under realistic threat conditions remain poorly understood. This review addresses that gap through a systematic analysis of 207 studies selected from 4447 records following the PRISMA 2020 guidelines, covering work published between 2020 and 2026 across cybersecurity and computer vision. A taxonomy of adversarial attacks is constructed across training and inference phases, defense mechanisms are examined with attention to their documented failure modes, and robustness evaluation practices are assessed across the surveyed literature. RL is analyzed in both offensive and defensive roles. Attack agents using RL achieve evasion rates of 74–97% against ML-based detectors, while RL-based defenses report robustness gains of up to 3× over static baselines under comparable threat conditions. XAI receives particular attention because the field treats it almost exclusively as a transparency mechanism, whereas the reviewed evidence shows that it also functions as an attack surface. Attribution methods such as LIME, SHAP, and Grad-CAM produce unreliable explanations under adversarial perturbation, and no system in the reviewed literature certifies that attribution properties are maintained when inputs are manipulated. The review concludes with an analysis of open problems and research directions for building systems that are robust against adaptive adversaries, interpretable under operational constraints, and auditable in environments where AI accountability is a legal requirement.
