Abstract:

Most network models are vulnerable to adversarial attack, which poses a serious threat to the security of network algorithms. Therefore, adversarial attack becomes an effective method to evaluate network security and robustness. The existing white-box attack methods have been able to achieve high success rates, but black-box condition remains to be improved. This paper referred to gradient optimization and introduced AdaN optimizer to the process of generating adversarial examples. The main purpose was to accelerate gradient convergence. Thus, the overfitting was relieved and transferability was enhanced. In order to further enhance the attack effectiveness, the method proposed in the article is combined with other data augmentation methods to form a more effective attack method. Besides, generating adversarial examples by ensemble models shows better performance on defense models. The experimental results show that the adversarial samples optimized using AdaN gradient can achieve higher success rates in black-box attacks than the current benchmark method and have better transferability.
