ArXiv, 2018
The burgeoning success of deep learning has raised the security and privacy concerns as more and more tasks are accompanied with sensitive data. Adversarial attacks in deep learning have emerged as one of the dominating security threat to a range of mission-critical deep learning systems and applications. This paper takes a holistic and principled approach to perform statistical characterization of adversarial examples in deep learning. We provide a general formulation of adversarial examples and elaborate on the basic principle for adversarial attack algorithm design. We introduce easy and hard categorization of adversarial attacks to analyze the effectiveness of adversarial examples in terms of attack success rate, degree of change in adversarial perturbation, average entropy of prediction qualities, and fraction of adversarial examples that lead to successful attacks. We conduct extensive experimental study on adversarial behavior in easy and hard attacks under deep learning mode...
Survey of Adversarial Attacks in Deep Learning Models
IRJET, 2022
Despite recent breakthroughs in a wide range of applications, machine learning models, particularly deep neural networks, have been demonstrated to be sensitive to adversarial assaults. Looking at these intelligent models from a security standpoint is critical; if the person/organization is uninformed, they must retrain the model and address the errors, which is both costly and time consuming. Attackers introduce carefully engineered perturbations into input, which are practically undetectable to humans but can lead models to make incorrect predictions. Hostile defense strategies are techniques for protecting models against adversarial input are called adversarial defense methods. These attacks can be performed on a range of models trained on images, text, time-series data. In our paper will discuss different kinds of attacks like White-Box attacks, Black-Box attacks etc on various models and also make them robust by using several defense approaches like adversarial training, Adversarial Detection, Input Denoising etc.
Adversarial Attacks and Defences: A Survey
ArXiv, 2018
Deep learning has emerged as a strong and efficient framework that can be applied to a broad spectrum of complex learning problems which were difficult to solve using the traditional machine learning techniques in the past. In the last few years, deep learning has advanced radically in such a way that it can surpass human-level performance on a number of tasks. As a consequence, deep learning is being extensively used in most of the recent day-to-day applications. However, security of deep learning systems are vulnerable to crafted adversarial examples, which may be imperceptible to the human eye, but can lead the model to misclassify the output. In recent times, different types of adversaries based on their threat model leverage these vulnerabilities to compromise a deep learning system where adversaries have high incentives. Hence, it is extremely important to provide robustness to deep learning algorithms against these adversaries. However, there are only a few strong countermeas...
Analysing Adversarial Examples for Deep Learning
2021
The aim of this work is to investigate adversarial examples and look for commonalities and disparities between different adversarial attacks and attacked classifier model behaviours. The research focuses on untargeted, gradient-based attacks. The experiment uses 16 attacks on 4 models and 1000 images. This resulted in 64,000 adversarial examples. The resulting classification predictions of the adversarial examples (adversarial labels) are analysed. It is found that light-weight neural network classifiers are more suspectable to attacks compared to the models with a larger or more complex architecture. It is also observed that similar adversarial attacks against a light-weight model often result in the same adversarial label. Moreover, the attacked models have more influence over the resulting adversarial label as compared to the adversarial attack algorithm itself. These finding are helpful in understanding the intriguing vulnerability of deep learning to adversarial examples.

The popularity of adapting deep neural networks (DNNs) in solving hard problems has increased substantially. Specifically, in the field of computer vision, DNNs are becoming a core element in developing many image and video classification and recognition applications. However, DNNs are vulnerable to adversarial attacks, in which, given a well-trained image classification model, a malicious input can be crafted by adding mere perturbations to misclassify the image. This phenomena raise many security concerns in utilizing DNNs in critical life applications which attracts the attention of academic and industry researchers. As a result, multiple studies have proposed discussing novel attacks that can compromise the integrity of state-of-the-art image classification neural networks. The raise of these attacks urges the research community to explore countermeasure methods to mitigate these attacks and increase the reliability of adapting DDNs in different major applications. Hence, various defense strategies have been proposed to protect DNNs against adversarial attacks. In this paper, we thoroughly review the most recent and state-of-the-art adversarial attack methods by providing an in-depth analysis and explanation of the working process of these attacks. In our review, we focus on explaining the mathematical concepts and terminologies of the adversarial attacks, which provide a comprehensive and solid survey to the research community. Additionally, we provide a comprehensive review of the most recent defense mechanisms and discuss their effectiveness in defending DNNs against adversarial attacks. Finally, we highlight the current challenges and open issues in this field as well as future research directions.

Detecting adversarial example attacks to deep neural networks
Proceedings of the 15th International Workshop on Content-Based Multimedia Indexing
Deep learning has recently become the state of the art in many computer vision applications and in image classification in particular. However, recent works have shown that it is quite easy to create adversarial examples, i.e., images intentionally created or modified to cause the deep neural network to make a mistake. They are like optical illusions for machines containing changes unnoticeable to the human eye. This represents a serious threat for machine learning methods. In this paper, we investigate the robustness of the representations learned by the fooled neural network, analyzing the activations of its hidden layers. Specifically, we tested scoring approaches used for kNN classification, in order to distinguishing between correctly classified authentic images and adversarial examples. The results show that hidden layers activations can be used to detect incorrect classifications caused by adversarial attacks.

A Tutorial on Adversarial Learning Attacks and Countermeasures
2022
Machine learning algorithms are used to construct a mathematical model for a system based on training data. Such a model is capable of making highly accurate predictions without being explicitly programmed to do so. These techniques have a great many applications in all areas of the modern digital economy and artificial intelligence. More importantly, these methods are essential for a rapidly increasing number of safety-critical applications such as autonomous vehicles and intelligent defense systems. However, emerging adversarial learning attacks pose a serious security threat that greatly undermines further such systems. The latter are classified into four types, evasion (manipulating data to avoid detection), poisoning (injection malicious training samples to disrupt retraining), model stealing (extraction), and inference (leveraging over-generalization on training data). Understanding this type of attacks is a crucial first step for the development of effective countermeasures. ...
Adversarial Attack on Machine Learning Models
International Journal of Innovative Technology and Exploring Engineering, 2019
Machine Learning (ML) models are applied in a variety of tasks such as network intrusion detection or malware classification. Yet, these models are vulnerable to a class of malicious inputs known as adversarial examples. These are slightly perturbed inputs that are classified incorrectly by the ML model. The mitigation of these adversarial inputs remains an open problem. As a step towards understanding adversarial examples, we show that they are not drawn from the same distribution than the original data, and can thus be detected using statistical tests. Using this knowledge, we introduce a complimentary approach to identify specific inputs that are adversarial. Specifically, we augment our ML model with an additional output, in which the model is trained to classify all adversarial inputs.
A Robust-Based Framework towards Resisting Adversarial Attack on Deep Learning Models
IJSES, 2021
Adversarial attack is a type of attack executed by an attacker in other to confuse a deep learning model to falsely classify a wrong input data as the correct data. This attack is being executed in two ways. The first one is the Poisoning attack which is being generated during training of a deep learning model. And the second one is the Evasion attack. In the evasion assault, the assaults' is being done on the test dataset. An evasion assault happens when the computer network is taken care of an "adversarial model", a painstakingly perturbed info that looks and feels precisely equivalent to its untampered duplicate to a human however that totally loses the classifier that. This system presents a robust based model towards the resistance of adversary assaults on deep learning models. The system presents two models using convolutional neural network algorithm. This model was trained on a Modified National Institute of Standards and Technology dataset (MNIST). An adversary (evasion) attacks was generated to in other to fools this models to misclassify result, therefore, seeing the wrong input data to be the right one. This adversarial examples was generated using a state-of-the-art library in python. The generated adversarial examples was being generated on the test data, in which the first model fails in resisting the attack, while the second model, which is our robust model resisted the adversarial attack on a good number of accuracy when tested for the first 100 images.
