I. ABSTRACT. We investigate the problem of information theoretically se- cure communication in a line network with erasure channels and state feedback.

This work is the first to characterize the secrecy capacity of a network of arbitrary size, with imperfect channels and feedback, and develops polynomial ...

Secret Message Capacity of a Line Network. A Papadopoulos, L Czap, C Fragouli. 52nd Annual Allerton Conference on Communication, Control, and Computing, 2014.

The secrecy capacity is defined as the rate at which one node transmits the secret information to other. 1. For a discrete memory-less AWGN wiretap channel, the ...

A series of recent papers in the literature have exactly characterized the secret message capacity for the case of a single link [2], a V-network (with 2 links) ...

Abstract—We study the secret message capacity of an ergodic block fading wiretap channel with partial channel state informa- tion at the transmitter and ...
