Abstract:

This paper studied the current typical JSMA against sample attack algorithm based on saliency graph, and proposes an improved JSMA against sample attack algorithm L-JSMA based on Logits vector. The algorithm proves that the attack effect is positively correlated with Logits ranking on MNIST data set and CIFAR-10 data set. In order to further verify the theory, attack the targets according to Logits on the Alexnet model and Inception-v3 model, and the conclusion is further proved. Through experimental analysis, it is found that the stronger the attack ability of JSMA derivative algorithm, the more it can make full use of the linear characteristics of neural network, and the stronger the linear correlation in the experimental results. Because neural networks have both linear and nonlinear characteristics, the attack effect is not strictly positively correlated with Logits. By discussing the nature of neural network of white box attack, it is helpful to understand the essential characteristics of neural network, and also referential for black box attack.
