Bounded Reasoning: Cognitive Hierarchy in Human-versus-AI Cyber Defense
Zahra Aref, Sheng Wei, Narayan B. Mandayam
Human-agent evaluations often compress interaction into a single performance score, even when human and automated policies adapt differently over time. We study this in a sequentia…
Human-AI Collaboration in Cloud Security: Cognitive Hierarchy-Driven Deep Reinforcement Learning
Zahra Aref, Sheng Wei, Narayan B. Mandayam
Given the complexity of multi-tenant cloud environments and the growing need for real-time threat mitigation, Security Operations Centers (SOCs) must adopt AI-driven adaptive defen…
Defense Against Advanced Persistent Threats in Dynamic Cloud Storage: A Colonel Blotto Game Approach
Minghui Min, Liang Xiao, Caixia Xie +2
Advanced Persistent Threat (APT) attackers apply multiple sophisticated methods to continuously and stealthily steal information from the targeted cloud storage systems and can eve…
Information-theoretically Secret Key Generation for Fading Wireless Channels
Chunxuan Ye, Suhas Mathur, Alex Reznik +3
The multipath-rich wireless environment associated with typical wireless usage scenarios is characterized by a fading channel response that is time-varying, location-sensitive, and…
Using the Physical Layer for Wireless Authentication in Time-Variant Channels
Liang Xiao, Larry Greenstein, Narayan Mandayam +1
The wireless medium contains domain-specific information that can be used to complement and enhance traditional security mechanisms. In this paper we propose ways to exploit the sp…
MIMO-Assisted Channel-Based Authentication in Wireless Networks
Liang Xiao, Larry Greenstein, Narayan Mandayam +1
Multiple-input multiple-output (MIMO) techniques allow for multiplexing and/or diversity gain, and will be widely deployed in future wireless systems. In this paper, we propose a M…
