The contemporary defense strategies in the market either cannot alleviate a variety of adversarial attacks primarily in a white box environment or do not have a standardized approach that can be applied to any form of the complex deep-learning models to make them inert from a variety of adversaries. Moreover, there is a need for standardized adversarial defense strategies for mitigating a variety of adversarial attacks to make our models more robust in a white box environment. In this project, we make use of three different state-of-the-art deep-learning architectures trained on 2 benchmarking datasets – CIFAR-10 and CIFAR-100, to analyze the difference in the performance of these models in the absence of an adversary as well as in the presence of an adversary in a white-box environment. We primarily use two white box attack methodologies – Fast Gradient Sign Method (FGSM) and Projected Gradient Descent (PGD) to plant adversarial samples using epsilon values ranging from 0.1 to 0.8. Furthermore, we go one step further to devise a defense strategy – Defensive Distillation, that can be applied to a deep-learning architecture to deplete the overall efficacy of FGSM and PGD attacks.||URI:||https://hdl.handle.net/10356/157133||Fulltext Permission:||restricted||Fulltext Availability:||With Fulltext|
