A Large-Scale Benchmark and Risk Assessment of Traffic Analysis Attacks on Cloud LLM Services
Shahrooz Pouryousef, Jesus Lopez, Saeefa Rubaiyat Nowmi +5
Cloud-based Large language model (LLM) services create a network-level traffic side channel that can expose model, prompt, and task behavior despite encryption. From packet sizes,…
DoSQ: A Cross-Layer Denial of Service Quality Attack by Exploiting Side Channels in 5G NR
Mahmudul Hassan Ashik, Moinul Hossain
The 3rd Generation Partnership Project (3GPP)'s Fifth Generation New Radio (5G NR) is critical to supporting mission-critical services. However, 5G systems are vulnerable to smart…
FLINT: Fingerprinting Federated Learning Architectures from 5G PHY-Layer Side Channels
Md Nahid Hasan Shuvo, Mahmudul Hassan Ashik, Moinul Hossain
Federated Learning (FL) over 5G cellular networks protects raw data but remains vulnerable to side-channel leakage. Prior fingerprinting attacks assume packet-level network visibil…
Analyzing the Impact of Adversarial Attacks on C-V2X-Enabled Road Safety: An Age of Information Perspective
Mahmudul Hassan Ashik, Moinul Hossain
The Cellular Vehicle-to-Everything (C-V2X), introduced and developed by the 3GPP, is a promising technology for the Autonomous Driving System (ADS). C-V2X aims to fulfill the Servi…
FLARE: A Wireless Side-Channel Fingerprinting Attack on Federated Learning
Md Nahid Hasan Shuvo, Moinul Hossain, Anik Mallik +2
Federated Learning (FL) enables collaborative model training across distributed devices while safeguarding data and user privacy. However, FL remains susceptible to privacy threats…
