Structural Limits of Soft Fusion in Multi-Warden Covert Communication
Abbas Arghavani, Subhrakanti Dey, Anders Ahlen
This paper investigates covert wireless communication with a Fusion Center (FC) that aggregates raw energy measurements from multiple Wardens via soft fusion. Extending our prior w…
Quickest Detection of Deception Attacks in Networked Control Systems with Physical Watermarking
Arunava Naha, Andre Teixeira, Anders Ahlen +1
In this paper, we propose and analyze an attack detection scheme for securing the physical layer of a networked control system against attacks where the adversary replaces the true…
Linear Regression with Distributed Learning: A Generalization Error Perspective
Martin Hellkvist, Ayça Özçelikkale, Anders Ahlén
Distributed learning provides an attractive framework for scaling the learning task by sharing the computational load over multiple nodes in a network. Here, we investigate the per…
Sequential detection of Replay attacks
Arunava Naha, Andre Teixeira, Anders Ahlen +1
One of the most studied forms of attacks on the cyber-physical systems is the replay attack. The statistical similarities of the replay signal and the true observations make the re…
Generalization Error for Linear Regression under Distributed Learning
Martin Hellkvist, Ayça Özçelikkale, Anders Ahlén
Distributed learning facilitates the scaling-up of data processing by distributing the computational burden over several nodes. Despite the vast interest in distributed learning, g…
Sequential Detection of Deception Attacks in Networked Control Systems with Watermarking
Somayeh Salimi, Subhrakanti Dey, Anders Ahlen
In this paper, we investigate the role of a physical watermarking signal in quickest detection of a deception attack in a scalar linear control system where the sensor measurements…
