Summary

The "SecApp" framework is introduced to enhance the robustness of Federated Reinforcement Learning (FRL) systems in safety-critical autonomous driving scenarios, addressing the largely unexplored threat of poisoning attacks. FRL is crucial for collaborative learning across multiple agents without sharing raw data, improving privacy and scalability in dynamic vehicular environments. Poisoning attacks can compromise the global control model by injecting malicious system parameters, creating potential hazards. "SecApp" counters this by integrating digital twins for rehearsal-based learning and leveraging historical aggregated model parameters alongside a selected central gradient. This ensures only benign data is aggregated, effectively mitigating malicious agent influence. Theoretical guarantees for "SecApp"'s convergence performance under poisoning attacks are provided, and its effectiveness is validated using digital twins that model realistic highway environments for autonomous vehicle control under adversarial conditions.

Key takeaway

For AI Security Engineers developing autonomous vehicle systems, you should prioritize integrating robust defense mechanisms against poisoning attacks in Federated Reinforcement Learning. "SecApp" offers a validated framework that uses digital twins and historical model parameters to ensure secure data aggregation. Implementing such a framework can significantly enhance the reliability and safety of your FRL-based control models, mitigating the risks of malicious parameter injection in safety-critical driving scenarios. Consider evaluating "SecApp"'s approach for your next-generation AV security protocols.
