LP formulations for secrecy over erasure networks with feedback
Athanasios Papadopoulos, Laszlo Czap, Christina Fragouli
We design polynomial time schemes for secure message transmission over arbitrary networks, in the presence of an eavesdropper, and where each edge corresponds to an erasure channel…
Secret Communication over Broadcast Erasure Channels with State-feedback
László Czap, Vinod M. Prabhakaran, Christina Fragouli +1
We consider a 1-to- communication scenario, where a source transmits private messages to receivers through a broadcast erasure channel, and the receivers feed back strictly…
Secret message capacity of a line network
Athanasios Papadopoulos, Laszlo Czap, Christina Fragouli
We investigate the problem of information theoretically secure communication in a line network with erasure channels and state feedback. We consider a spectrum of cases for the pri…
Multi-terminal Secrecy in a Linear Non-coherent Packetized Networks
Mahdi Jafari Siavoshani, Christina Fragouli
We consider a group of m+1 trusted nodes that aim to create a shared secret key K over a network in the presence of a passive eavesdropper, Eve. We assume a linear non-coherent net…
Approximate Capacity of Gaussian Interference-Relay Networks with Weak Cross Links
Soheil Mohajer, Suhas N. Diggavi, Christina Fragouli +1
In this paper we study a Gaussian relay-interference network, in which relay (helper) nodes are to facilitate competing information flows over a wireless network. We focus on a two…
