Covertly Controlling a Linear System
Barak Amihood, Asaf Cohen
Consider the problem of covertly controlling a linear system. In this problem, Alice desires to control (stabilize or change the behavior of) a linear system, while keeping an obse…
Perfectly Covert Communication Assisted by an Intelligent Reflecting Surface
Or Elimelech, Asaf Cohen
This work investigates perfectly covert communication assisted by a passive Intelligent Reflecting Surface (IRS). In contrast to most existing IRS-assisted covert communication stu…
Order-optimal Joint Transmission and Identification in Massive Multi-User MIMO via Group Testing
George Vershinin, Asaf Cohen, Omer Gurewitz
The number of wireless devices which are connected to a single Wireless Local Area Network continues to grow each year. As a result, the orchestration of so many devices becomes a…
Centralized vs Decentralized Targeted Brute-Force Attacks: Guessing with Side-Information
Salman Salamatian, Wasim Huleihel, Ahmad Beirami +2
According to recent empirical studies, a majority of users have the same, or very similar, passwords across multiple password-secured online services. This practice can have disast…
Compute-and-Forward in Large Relaying Systems: Limitations and Asymptotically Optimal Scheduling
Ori Shmuel, Asaf Cohen, Omer Gurewitz
Compute and Forward (CF) is a coding scheme which enables receivers to decode linear combinations of simultaneously transmitted messages while exploiting the linear properties of l…
Private Information Retrieval Over Gaussian MAC
Ori Shmuel, Asaf Cohen
Consider the problem of Private Information Retrieval (PIR), where a user wishes to retrieve a single message from non-communicating and non-colluding databases (servers). All…
