Network Equivalence in the Presence of an Eavesdropper
Theodoros K. Dikaliotis, Hongyi Yao, Tracey Ho +2
We consider networks of noisy degraded wiretap channels in the presence of an eavesdropper. For the case where the eavesdropper can wiretap at most one channel at a time, we show t…
On the Delay Advantage of Coding in Packet Erasure Networks
Theodoros K. Dikaliotis, Alexandros G. Dimakis, Tracey Ho +1
We consider the delay of network coding compared to routing with retransmissions in packet erasure networks with probabilistic erasures. We investigate the sub-linear term in the b…
Low-Complexity Near-Optimal Codes for Gaussian Relay Networks
Theodoros K. Dikaliotis, Hongyi Yao, Salman Avestimehr +2
We consider the problem of information flow over Gaussian relay networks. Similar to the recent work by Avestimehr \emph{et al.} [1], we propose network codes that achieve up to a…
Multiple-access Network Information-flow and Correction Codes
Theodoros K. Dikaliotis, Tracey Ho, Sidharth Jaggi +5
This work considers the multiple-access multicast error-correction scenario over a packetized network with malicious edge adversaries. The network has min-cut and packets o…
Security in Distributed Storage Systems by Communicating a Logarithmic Number of Bits
Theodoros K. Dikaliotis, Alexandros G. Dimakis, Tracey Ho
We investigate the problem of maintaining an encoded distributed storage system when some nodes contain adversarial errors. Using the error-correction capabilities that are built i…
Multiple Access Network Information-flow And Correction codes
Hongyi Yao, Theodoros K. Dikaliotis, Sidharth Jaggi +1
The network communication scenario where one or more receivers request all the information transmitted by different sources is considered. We introduce distributed polynomial-time…
