Finite-blocklength performance of polar wiretap codes under a total variation secrecy constraint
Laura Luzzi, Valerio Bioglio
We study the performance of polarizing codes over a degraded symmetric wiretap channel under a total variation distance (TVD) secrecy constraint. We show that the leakage can be bo…

Covert Capacity of AWGN Channels under Average Error Probability
C. Bouette, L. Luzzi, M. Bloch
We derive upper and lower bounds for the covert capacity of Additive White Gaussian Noise channels when measuring reliability in terms of the average error probability and covertne…

Covert Communication Over Additive-Noise Channels
Cécile Bouette, Laura Luzzi, Ligong Wang
We study the fundamental limits of covert communications over general memoryless additive-noise channels. We assume that the legitimate receiver and the eavesdropper share the same…
