Physical-Layer Security over Correlated Erasure Channels

W. K. Harrison, J. Almeida, S. W. McLaughlin +1

We explore the additional security obtained by noise at the physical layer in a wiretap channel model setting. Security enhancements at the physical layer have been proposed recent…

Coding for Cryptographic Security Enhancement using Stopping Sets

W. K. Harrison, J. Almeida, S. W. McLaughlin +1

In this paper we discuss the ability of channel codes to enhance cryptographic secrecy. Toward that end, we present the secrecy metric of degrees of freedom in an attacker's knowle…

Strong Secrecy on the Binary Erasure Wiretap Channel Using Large-Girth LDPC Codes

Arunkumar Subramanian, Andrew Thangaraj, Matthieu Bloch +1

For an arbitrary degree distribution pair (DDP), we construct a sequence of low-density parity-check (LDPC) code ensembles with girth growing logarithmically in block-length using…

Strong Secrecy for Erasure Wiretap Channels

Ananda T. Suresh, Arunkumar Subramanian, Andrew Thangaraj +2

We show that duals of certain low-density parity-check (LDPC) codes, when used in a standard coset coding scheme, provide strong secrecy over the binary erasure wiretap channel (BE…

Tandem Coding and Cryptography on Wiretap Channels: EXIT Chart Analysis

Willie K Harrison, Steven W. McLaughlin

Traditional cryptography assumes an eavesdropper receives an error-free copy of the transmitted ciphertext. Wyner's wiretap channel model recognizes that at the physical layer both…

MDS codes on the erasure-erasure wiretap channel

Arunkumar Subramanian, Steven W. McLaughlin

This paper considers the problem of perfectly secure communication on a modified version of Wyner's wiretap channel II where both the main and wiretapper's channels have some erasu…
