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…
Physical-Layer Security: Combining Error Control Coding and Cryptography
Willie K Harrison, Steven W. McLaughlin
In this paper we consider tandem error control coding and cryptography in the setting of the {\em wiretap channel} due to Wyner. In a typical communications system a cryptographic…
The Design of Efficiently-Encodable Rate-Compatible LDPC Codes
Jaehong Kim, Aditya Ramamoorthy, Steven W. McLaughlin
We present a new class of irregular low-density parity-check (LDPC) codes for moderate block lengths (up to a few thousand bits) that are well-suited for rate-compatible puncturing…
