Game of Trojans: Adaptive Adversaries Against Output-based Trojaned-Model Detectors

Dinuka Sahabandu, Xiaojun Xu, Arezoo Rajabi +4

We propose and analyze an adaptive adversary that can retrain a Trojaned DNN and is also aware of SOTA output-based Trojaned model detectors. We show that such an adversary can ens…
