Evolutionary algorithms deceive humans and machines at image classification: An extended proof of concept on two scenarios
The range of applications of Neural Networks encompasses image classification. However, Neural Networks are vulnerable to attacks, and may misclassify adversarial images, leading to potentially disastrous consequences. Pursuing some of our previous work, we provide an extended proof of concept of a black-box, targeted, non-parametric attack using evolutionary algorithms to fool both Neural Networks and humans at the task of image classification. Our feasibility study is performed on VGG-16 trained on CIFAR-10.

A new digital signature scheme based on the hardness of some expanded root problems
This paper proposes a new digital signature scheme based on the difficulty of solving expanded root problems on Zp. Therefore, the safety level of the algorithms built by this method will be ensured by the difficulty of solving expanded root problems. In mathematics, this is a form of problem without solution before. Therefore, the newly proposed scheme can be used to develop a digital signature algorithm class for applications that require a high security in practice.
