Complexity of statistical attacks on QC‐LDPC code‐based cryptosystems [PDF]

IET Information Security, 2020
Public‐key cryptosystems built on quasi‐cyclic (QC) low‐density parity‐check and moderate‐density parity‐check codes are promising candidates for post‐quantum cryptography, since they are characterised by compact keys and high algorithmic efficiency. The main issue with this kind of system is represented by the fact that, since the decoding procedure ...

Analysis of Minimal LDPC Decoder System on a Chip Implementation [PDF]

, 2015
This paper presents a practical method of potential replacement of several different Quasi-Cyclic Low-Density Parity-Check (QC-LDPC) codes with one, with the intention of saving as much memory as required to implement the LDPC encoder and decoder in a ...

Quasi-Cyclic LDPC Codes based on Pre-Lifted Protographs

, 2014
Quasi-cyclic low-density parity-check (QC-LDPC) codes based on protographs are of great interest to code designers because analysis and implementation are facilitated by the protograph structure and the use of circulant permutation matrices for ...

A construction of the high-rate regular quasi-cyclic LDPC codes

EURASIP Journal on Wireless Communications and Networking, 2019
In this paper, a scheme to construct the high-rate regular quasi-cyclic low-density parity-check (QC-LDPC) codes is developed based on the finite geometry low-density parity-check (LDPC) codes.

Design and Analysis of Time-Invariant SC-LDPC Convolutional Codes With Small Constraint Length

, 2017
In this paper, we deal with time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPC-CCs). Classic design approaches usually start from quasi-cyclic low-density parity-check (QC-LDPC) block codes and exploit suitable ...
