Malicious adversaries can attack machine learning models to infer sensitive information or damage the system by launching a series of evasion attacks. Although various work addresses privacy and security concerns, they focus on individual defenses, but in practice, models may undergo simultaneous attacks. This study explores the combination of adversarial training and differentially private training to defend against simultaneous attacks. While differentially-private adversarial training, as presented in DP-Adv, outperforms the other state-of-the-art methods in performance, it lacks formal privacy guarantees and empirical validation. Thus, in this work, we benchmark the performance of this technique using a membership inference attack and empirically show that the resulting approach is as private as non-robust private models. This work also highlights the need to explore privacy guarantees in dynamic training paradigms.

使用敌对训练和差分隐私训练的组合，本研究探讨了针对同时攻击的防御方法。通过使用成员推断攻击来基准测试DP-Adv技术的性能，并实证显示该方法的隐私性与非鲁棒私有模型相当。此外，该研究还强调了在动态训练范式中探索隐私保证的需求。
