Fundamental limits of quantum-secure covert communication over bosonic channels
Michael S. Bullock, Christos N. Gagatsos, Saikat Guha +1
We investigate the fundamental limit of quantum-secure covert communication over the lossy thermal noise bosonic channel, the quantum-mechanical model underlying many practical cha…
Secret key distillation across a quantum wiretap channel under restricted eavesdropping
Ziwen Pan, Kaushik P. Seshadreesan, William Clark +4
The theory of quantum cryptography aims to guarantee unconditional information-theoretic security against an omnipotent eavesdropper. In many practical scenarios, however, the assu…
Covert Wireless Communication with Artificial Noise Generation
Ramin Soltani, Dennis Goeckel, Don Towsley +2
Covert communication conceals the transmission of the message from an attentive adversary. Recent work on the limits of covert communication in additive white Gaussian noise (AWGN)…
A de Bruijn identity for discrete random variables
Oliver Johnson, Saikat Guha
We discuss properties of the "beamsplitter addition" operation, which provides a non-standard scaled convolution of random variables supported on the non-negative integers. We give…
Covert Single-hop Communication in a Wireless Network with Distributed Artificial Noise Generation
Ramin Soltani, Boulat Bash, Dennis Goeckel +2
Covert communication, also known as low probability of detection (LPD) communication, prevents the adversary from knowing that a communication is taking place. Recent work has demo…
Covert Communication in the Presence of an Uninformed Jammer
Tamara V. Sobers, Boulat A. Bash, Saikat Guha +2
Recent work has established that when transmitter Alice wishes to communicate reliably to recipient Bob without detection by warden Willie, with additive white Gaussian noise (AWGN…
