Feedback Coding Enables Inference-Time Covert Agentic Communication
Sidong Guo, Sajani Vithana, Atefeh Gilani +3
As large language models (LLMs) are increasingly used to automate digital interactions, users can leverage LLM-generated text as cover for covert communication within seemingly ben…
Covert Multi-bit LLM Watermarking: An Information Theory and Coding Approach
Sidong Guo, Tyler Kann, Teodora Baluta +1
We study the problem of multi-bit watermarking for non-autoregressive large language models (LLMs). We introduce an information-theoretic model inspired by diffusion language model…
Secure Integrated Sensing and Communication against Communication and Sensing Eavesdropping
Sidong Guo, Matthieu R. Bloch
Sensing privacy and communication confidentiality play fundamentally different but interconnected roles in adversarial wireless environments. Capturing this interplay within a sing…
Designing Affine OCDM Systems with Maximum Diversity
Sidong Guo, Xiaoli Ma, Yiyin Wang
This work considers the problem of enabling maximum multipath diversity of orthogonal chirp division multiplexing (OCDM)-based systems. We define and study an Affine OCDM (A-OCDM)…
Carrier Frequency Offset Estimation for OCDM with Null Subchirps
Sidong Guo, Yiyin Wang, Xiaoli Ma
In this paper, we investigate the carrier frequency offset (CFO) identifiability problem in orthogonal chirp division multiplexing (OCDM) systems. We propose a transmission scheme…
Precheck Sequence Based False Base Station Detection During Handover: A Physical Layer Security Scheme
Xiangyu Li, Kaiwen Zheng, Sidong Guo +1
False Base Station (FBS) attack has been a severe security problem for the cellular network since 2G era. During handover, the user equipment (UE) periodically receives state infor…
Sensing-Aided Peer-to-Peer Millimeter-Wave Communication
Xiangyu Li, Sidong Guo, Shez Malik
One of the bottlenecks of modern communications is to enable sensing and mutual communication simultaneously without causing scheduling conflicts, and how sensing may be leveraged…
