trojanzoo 1.0.6

a universal pytorch platform to conduct security researches

TrojanZoo

This is the code implementation (pytorch) for our paper:
TROJANZOO: Everything you ever wanted to know about neural backdoors (but were afraid to ask)

TrojanZoo provides a universal pytorch platform to conduct security researches (especially backdoor attacks/defenses) of image classification in deep learning. It is composed of two packages: trojanzoo and trojanvision. trojanzoo contains abstract classes and utilities, while trojanvision contains abstract and concrete ones for image classification task.

Note: This repository is also maintained to cover the implementation of
our kdd 2020 paper AdvMind: Inferring Adversary Intent of Black-Box Attacks
and ccs 2020 paper A Tale of Evil Twins: Adversarial Inputs versus Poisoned Models.

Features

1. Colorful and verbose output!

   Note: enable with --color for color and --verbose for verbose.
   To open an interactive window with color, use python - --color

2. Modular design (plug and play)
3. Good code linting support (this package requires python>=3.9)
4. Register your own module to the library.
5. Native Pytorch Output
   trojanzoo and trojanvision provides API to generate raw pytorch instances, which makes it flexible to work with native pytorch and other 3rd party libraries.

   trojanzoo.datasets.DataSet can generate torch.utils.data.Dataset and torch.utils.data.DataLoader
trojanzoo.models.Model attribute _model is torch.nn.Module, attribute model is torch.nn.DataParallel
   Specifically, trojanvision.datasets.ImageSet can generate torchvision.datasets.VisionDataset, trojanvision.datasets.ImageFolder can generate torchvision.datasets.ImageFolder

6. Enable pytorch native AMP(Automatic Mixed Precision) with --amp for training
7. Flexible Configuration Files
8. Good help information to check arguments. (-h or --help)
9. Detailed and well-organized summary() for each module.

Installation

1. pip install trojanzoo
2. (todo) conda install trojanzoo
3. docker pull local0state/trojanzoo
4. (for develop)python setup.py develop

   This could install the github repo package but avoid copying files to site_packages, so that during developing TrojanZoo, you don't need move example files to the root directory of repo.

Quick Start

You can use the provided example scripts to reproduce the evaluation results in our paper.

Note: The program won't save results without --save

1. Train a model:
   e.g. ResNetComp18 on CIFAR10 with 95% Acc

   python ./examples/train.py --color --tqdm --verbose 1 --amp --dataset cifar10 --model resnetcomp18 --epoch 300 --lr 0.1 --lr_scheduler --lr_step_size 100 --save
   

2. Test backdoor attack (e.g., BadNet):
   e.g. BadNet with ResNetComp18 on CIFAR10

   python ./examples/backdoor_attack.py --color --tqdm --verbose 1 --pretrain --validate_interval 1 --amp --dataset cifar10 --model resnetcomp18 --attack badnet --random_init --epoch 50 --lr 0.01 --save
   

3. Test backdoor defense (e.g., Neural Cleanse):
   e.g. Neural Cleanse against BadNet

   python ./examples/backdoor_defense.py --color --tqdm --verbose 1 --pretrain --validate_interval 1 --dataset cifar10 --model resnetcomp18 --attack badnet --defense neural_cleanse --random_init --epoch 50 --lr 0.01
   

IMC

python ./examples/backdoor_attack.py --color --tqdm --verbose 1 --pretrain --validate_interval 1 --amp --dataset cifar10 --model resnetcomp18 --attack imc --random_init --epoch 50 --lr 0.01 --save

AdvMind

(with attack adaptive and model adaptive)

python ./examples/adv_defense.py --color --tqdm --verbose 1 --pretrain --validate_interval 1 --dataset cifar10 --model resnetcomp18 --attack pgd --defense advmind --attack_adapt --defense_adapt

Detailed Usage

Configuration file structure

All arguments in the parser are able to set default values in configuration files.
If argument values are not set in the config files, we will use the default values of __init__()

Parameters Config: (priority ascend order)

The higher priority config will override lower priority ones.
Within each priority channel, trojanvision configs will overwrite trojanzoo

1. Package Default: /trojanzoo/configs/, /trojanvision/configs/

   These are package default settings. Please don't modify them.
   You can use this as a template to set other configs.

2. User Default: Not decided yet.

   (Enable it in the code trojanzoo/configs/__init__.py, trojanvision/configs/__init__.py)

3. Workspace Default: /configs/trojanzoo/, /configs/trojanvision/
4. Custom Config: --config [config location]
5. CMD parameters: --[parameter] [value]

Store path of Dataset, Model, Attack & Defense Results

Modify them in corresponding config files and command-line arguments.

Dataset: --data_dir (./data/data)
Model: --model_dir (./data/model)
Attack: --attack_dir (./data/attack)
Defense: --defense_dir (./data/defense)

Output Verbose Information:

1. CMD modules: --verbose 1
2. Colorful output: --color
3. tqdm progress bar: --tqdm
4. Check command-line argument usage: --help
5. AdvMind verbose information: --output [number]

Use your DIY Dataset/Model/Attack/Defense

1. Follow our example to write your DIY class. (CIFAR10, ResNet, IMC, Neural Cleanse)

   It's necessary to subclass our base class. (Dataset, Model, Attack, Defense)
   Optional base classes depending on your use case: (ImageSet, ImageFolder, ImageModel)

2. Register your DIY class in trojanvision

   Example: trojanvision.attacks.class_dict[attack_name]=AttackClass

3. Create your config files if necessary.
   No need to modify any codes. Just directly add {attack_name}.yml (.json) in the config directory.
4. Good to go!

Todo List

1. Sphinx Docs
2. Unit test
