DiffAttack: Evasion Attacks Against Diffusion-Based Adversarial Purification

Implementation of DiffAttack: Evasion Attacks Against Diffusion-Based Adversarial Purification [NeurIPS 2023].

Diffattack is a strong adversarial attack against diffusion-based purification defenses. We provide the following scripts for reproducing the results.

Environment and Pretrained models

Please refer to requirement.txt for the required packages of running the codes in the repo.

Put the folder models and pretrained under DiffAttack_Score_Based/ and DiffAttack_DDPM_Based/.

Attack against score-based purification

AdjAttack from DiffPure

Please refer to DiffPure for the adjattack against score-based diffusion purification defenses.

DiffAttack

The scripts are provided in DiffAttack_Score_Based/run_scripts/cifar10/ for CIFAR-10.
