Adversarial Library

This library contains various resources related to adversarial attacks implemented in PyTorch. It is aimed at researchers looking for implementations of state-of-the-art attacks.

The code was written to maximize efficiency (e.g. by preferring low-level functions from PyTorch) while retaining simplicity (e.g. by avoiding abstractions). As a consequence, most of the library, and especially the attacks, is implemented using pure functions (whenever possible).

While focused on attacks, this library also provides several utilities related to adversarial attacks: distances (SSIM, CIEDE2000, LPIPS), visdom callback, projections, losses, and helper functions. Most notably the function run_attack from utils/attack_utils.py performs an attack on a model given the inputs and labels, with fixed batch size, and reports complexity-related metrics (run-time and forward/backward propagations).

Dependencies

The goal of this library is to be up-to-date with newer versions of PyTorch so the dependencies are expected to be updated regularly (possibly resulting in breaking changes).

• pytorch>=1.8.0
• torchvision>=0.9.0
• tqdm>=4.48.0
• visdom>=0.1.8

Installation

You can either install using:

pip install git+https://github.com/jeromerony/adversarial-library

Attacks

Currently the following attacks are implemented in the adv_lib.attacks module:

Bold means that this repository contains the official implementation.

Type refers to the goal of the attack:

• Minimal attacks aim to find the smallest adversarial perturbation w.r.t. a given distance;
• Budget attacks aim to find an adversarial perturbation within a distance budget (and often to maximize a loss as well).

Distances

The following distances are available in the utils adv_lib.distances module:

• Lp-norms
• SSIM https://ece.uwaterloo.ca/~z70wang/research/ssim/
• MS-SSIM https://ece.uwaterloo.ca/~z70wang/publications/msssim.html
• CIEDE2000 color difference http://www2.ece.rochester.edu/~gsharma/ciede2000/ciede2000noteCRNA.pdf
• LPIPS https://arxiv.org/abs/1801.03924
