FlyBlind: Cross-Slice Timeliness Attacks on UAV Situational Awareness over 5G
Wagner Comin Sonaglio, Ágney Lopes Roth Ferraz, Sidnei Barbieri +3
Beyond Visual Line of Sight (BVLOS) Uncrewed Aerial Systems (UAS) operating over 5G Standalone (SA) networks use a shared User Plane for both command-and-control (C2) data and vide…
POLARIS: PHY-Aware Spectrum Steering for Dynamic Spectrum Sharing
Stavros Dimou, Guevara Noubir
Dynamic Spectrum Sharing (DSS) enables flexible activation of additional spectrum resources but leaves open a key runtime question: once new spectrum becomes available, which steer…
When Connectivity Is Not Enough: Cross-Layer Attacks on UAV C2 over 5G
Wagner Comin Sonaglio, Ágney Lopes Roth Ferraz, André Elias Melo +3
Beyond Visual Line of Sight (BVLOS) unmanned aerial vehicle (UAV) operations increasingly use 5G standalone (SA) networks for command and control (C2) between the UAV and the groun…
AirCatch: Effectively tracing advanced tag-based trackers
Abhishek Kumar Mishra, Swadeep, Guevara Noubir +1
Tag-based tracking ecosystems help users locate lost items, but can be leveraged for unwanted tracking and stalking. Existing protocol-driven defenses and prior academic solutions…
ARGOS: Anomaly Recognition and Guarding through O-RAN Sensing
Stavros Dimou, Guevara Noubir
Rogue Base Station (RBS) attacks, particularly those exploiting downgrade vulnerabilities, remain a persistent threat as 5G Standalone (SA) deployments are still limited and User E…
Establishing Trust in the Beyond-5G Core Network using Trusted Execution Environments
Marinos Vomvas, Norbert Ludant, Guevara Noubir
The fifth generation (5G) of cellular networks starts a paradigm shift from the traditional monolithic system design to a Service Based Architecture, that fits modern performance r…
Unprotected 4G/5G Control Procedures at Low Layers Considered Dangerous
Norbert Ludant, Marinos Vomvas, Guevara Noubir
Over the years, several security vulnerabilities in the 3GPP cellular systems have been demonstrated in the literature. Most studies focus on higher layers of the cellular radio st…
An Efficient Radar Receiver for OFDM-based Joint Radar and Communication Systems
Mamady Delamou, Kawtar Zerhouni, Guevara Noubir +1
We propose in this work a radar detection system for orthogonal-frequency division multiplexing (OFDM) transmission. We assume that the transmitting antenna Tx is colocated with a…
DEFORM: A Practical, Universal Deep Beamforming System
Hai N. Nguyen, Guevara Noubir
We introduce, design, and evaluate a set of universal receiver beamforming techniques. Our approach and system DEFORM, a Deep Learning (DL) based RX beamforming achieves significan…
Towards an AI-Driven Universal Anti-Jamming Solution with Convolutional Interference Cancellation Network
Hai N. Nguyen, Guevara Noubir
Wireless links are increasingly used to deliver critical services, while intentional interference (jamming) remains a very serious threat to such services. In this paper, we are co…
Spectro-Temporal RF Identification using Deep Learning
Hai N. Nguyen, Marinos Vomvas, Triet Vo-Huu +1
RF emissions detection, classification, and spectro-temporal localization are crucial not only for tasks relating to understanding, managing, and protecting the RF spectrum, but al…
Spectrum-Flexible Secure Broadcast Ranging
Tien D. Vo-Huu, Triet D. Vo-Huu, Guevara Noubir
Secure ranging is poised to play a critical role in several emerging applications such as self-driving cars, unmanned aerial systems, wireless IoT devices, and augmented reality. I…
A Privacy-Preserving Longevity Study of Tor's Hidden Services
Amirali Sanatinia, Jeman Park, Erik-Oliver Blass +2
Tor and hidden services have emerged as a practical solution to protect user privacy against tracking and censorship. At the same time, little is known about the lifetime and natur…
Mitigating Location Privacy Attacks on Mobile Devices using Dynamic App Sandboxing
Sashank Narain, Guevara Noubir
We present the design, implementation and evaluation of a system, called MATRIX, developed to protect the privacy of mobile device users from location inference and sensor side-cha…
Security of GPS/INS based On-road Location Tracking Systems
Sashank Narain, Aanjhan Ranganathan, Guevara Noubir
Location information is critical to a wide-variety of navigation and tracking applications. Today, GPS is the de-facto outdoor localization system but has been shown to be vulnerab…
Honey Onions: a Framework for Characterizing and Identifying Misbehaving Tor HSDirs
Amirali Sanatinia, Guevara Noubir
In the last decade, Tor proved to be a very successful and widely popular system to protect users' anonymity. However, Tor remains a practical system with a variety of limitations,…
Cascading Denial of Service Attacks on Wi-Fi Networks
Liangxiao Xin, David Starobinski, Guevara Noubir
We unveil the existence of a vulnerability in Wi-Fi, which allows an adversary to remotely launch a Denial-of-Service (DoS) attack that propagates both in time and space. This vuln…
