EG-LDPC Codes for the Erasure Wiretap Channel



Abstract

The wiretap channel model, proposed by Wyner,
has been studied by various authors from the perspectives of
security, reliability and cryptographic protocols. A basic theme
of these discussions has been information theoretically secure
communication whose degree of secrecy can be theoretically
proved. This paper explains a practical implementation of Euclidean

Introduction
A low-density parity-check (LDPC) code is a linear error correcting code, a method of transmitting a message over a noisy transmission channel by adding redundancy to the data bits. LDPC codes are capacity approaching codes, which means that practical constructions exist that allow for low error probability decoding at noise close to the theoretical maximum (the Shannon limit). LDPC codes are finding increasing use in data-corrupting noise is desired (10 Gbps Ethernet, DVBS-S, etc).

OpenGL is a widely-accepted application programming interface (API) for interactive 3D graphics rendering and 2D imaging. It provides device-independent support for common low-level 3D graphics drawing operations such as polygon specification, basic lighting control, transformation specification, and framebuffer operations like blending and depth-buffering.

It also provides mechanisms for sending and retrieving 2D images to and from the framebuffer, and integrates 3D graphics with 2D imaging through texture mapping. While other low-level gra ....etc

Abstract
Low-density parity-check (LDPC) code, a very promising near-optimal error correction code (ECC), is being widely considered in next generation industry standards. The VLSI implementation of high-speed LDPC decoder remains a big challenge. This paper presents the construction of a new class of implementation-oriented LDPC codes, namely shift-LDPC codes. With girth optimization, this kind of codes can perform as well as computer generated random codes. More importantly, the decoder can be efficiently implemented to obtain very h ....etc
