Abstract

Recently backdoor attack has become an emerging threat to the security of deep neural network (DNN) models. To date, most of the existing studies focus on backdoor attack against the uncompressed model; while the vulnerability of compressed DNNs, which are widely used in the practical applications, is little exploited yet. In this paper, we propose to study and develop Robust and Imperceptible Backdoor Attack against Compact DNN models (RIBAC). By performing systematic analysis and exploration on the important design knobs, we propose a framework that can learn the proper trigger patterns, model parameters and pruning masks in an efficient way. Thereby achieving high trigger stealthiness, high attack success rate and high model efficiency simultaneously. Extensive evaluations across different datasets, including the test against the state-of-the-art defense mechanisms, demonstrate the high robustness, stealthiness and model efficiency of RIBAC.

Step 1 - Setup Environment

Please install all packages

pip install torch==1.10.1+cu111 torchvision==0.11.2+cu111 torchaudio==0.10.1 -f https://download.pytorch.org/whl/torch_stable.html

pip install -r requirements.txt

Step 2 - Train Pretrain Model

CIFAR10 Pretrain (100 epochs)

python train.py --description pretrain_cifar10 --module pretrain --dataset cifar10 --max_epochs 100 --gpu_id 0 --learning_rate 0.001

Step 3 - Train Corresponding Target Model

• Default uses 60 epochs for all experiments. Debug use only 1 epoch.
• Default uses Adam with learning_rate 3e-4. For some experiments, if Adam fails to reach high accuracy, use SGD with learning_rate 0.01
