Realistic Website Fingerprinting By Augmenting Network Trace

1 code implementation18 Sep 2023 Alireza Bahramali, Ardavan Bozorgi, Amir Houmansadr

Our extensive open-world and close-world experiments demonstrate that under practical evaluation settings, our WF attacks provide superior performances compared to the state-of-the-art; this is due to their use of augmented network traces for training, which allows them to learn the features of target traffic in unobserved settings.

Truveta Mapper: A Zero-shot Ontology Alignment Framework

1 code implementation24 Jan 2023 Mariyam Amir, Murchana Baruah, Mahsa Eslamialishah, Sina Ehsani, Alireza Bahramali, Sadra Naddaf-sh, Saman Zarandioon

In this paper, a new perspective is suggested for unsupervised Ontology Matching (OM) or Ontology Alignment (OA) by treating it as a translation task.

Robust Adversarial Attacks Against DNN-Based Wireless Communication Systems

no code implementations1 Feb 2021 Alireza Bahramali, Milad Nasr, Amir Houmansadr, Dennis Goeckel, Don Towsley

We show that in the presence of defense mechanisms deployed by the communicating parties, our attack performs significantly better compared to existing attacks against DNN-based wireless systems.

Blind Adversarial Network Perturbations

1 code implementation16 Feb 2020 Milad Nasr, Alireza Bahramali, Amir Houmansadr

Deep Neural Networks (DNNs) are commonly used for various traffic analysis problems, such as website fingerprinting and flow correlation, as they outperform traditional (e. g., statistical) techniques by large margins.

DeepCorr: Strong Flow Correlation Attacks on Tor Using Deep Learning

no code implementations22 Aug 2018 Milad Nasr, Alireza Bahramali, Amir Houmansadr

Flow correlation is the core technique used in a multitude of deanonymization attacks on Tor.
