Assessing and countering reaction attacks against post-quantum public-key cryptosystems based on QC-LDPC codes

, 2018
Code-based public-key cryptosystems based on QC-LDPC and QC-MDPC codes are promising post-quantum candidates to replace quantum vulnerable classical alternatives.

Construction of Rate-Compatible Raptor-Like Quasi-Cyclic LDPC Code With Edge Classification for IDMA Based Random Access

IEEE Access, 2019
Recently, rate-compatible raptor-like quasi-cyclic low-density parity-check (RL-QC-LDPC) codes, which are a typical class of multi-edge type LDPC codes with excellent performance and high flexibility, have been adopted in the technical specification of ...

Analysis of reaction and timing attacks against cryptosystems based on sparse parity-check codes

, 2019
In this paper we study reaction and timing attacks against cryptosystems based on sparse parity-check codes, which encompass low-density parity-check (LDPC) codes and moderate-density parity-check (MDPC) codes.

QC-LDPC Codes from Difference Matrices and Difference Covering Arrays

IEEE Access, 2022
Abstract We give a framework for generalizing LDPC code constructions that use Transversal Designs or related structures such as mutually orthogonal Latin squares. Our construction offers a broader range of code lengths and codes rates. Similar earlier constructions rely on the existence of finite fields of order a power of a prime. In contrast

Constructing Large Girth QC Protograph LDPC Codes Based on PSD-PEG Algorithm

IEEE Access, 2017
For a given base graph, the lifted graph can be obtained by a copy-and-permute procedure. If the permutation is cyclic, the lifted graph corresponds to a quasi-cyclic (QC) protograph low-density parity-check (LDPC) code.

Tanner (3, 23)-Regular QC-LDPC Codes: Cycle Structure and Girth Distribution

IEEE Access
This paper studies a class of quasi-cyclic LDPC (QC-LDPC) codes, i.e., Tanner (3, 23)-regular QC-LDPC codes of code length $23p$ with $p$ being a prime and $p \equiv 1 (\mathrm {mod} 69)$ .

Distance Properties of Short LDPC Codes and their Impact on the BP, ML and Near-ML Decoding Performance

, 2017
Parameters of LDPC codes, such as minimum distance, stopping distance, stopping redundancy, girth of the Tanner graph, and their influence on the frame error rate performance of the BP, ML and near-ML decoding over a BEC and an AWGN channel are studied ...

Efficient Search of Compact QC-LDPC and SC-LDPC Convolutional Codes with Large Girth

, 2018
We propose a low-complexity method to find quasi-cyclic low-density parity-check block codes with girth 10 or 12 and shorter length than those designed through classical approaches.

7.7Gbps encoder design for IEEE 802.11n/ac QC-LDPC codes [PDF]

2012 International SoC Design Conference (ISOCC), 2012
This paper proposes a high throughput encoding process and encoder architecture for quasi-cyclic low-density parity-check (QC-LDPC) codes in IEEE 802.11n/ac standards. In order to achieve the high throughput with low complexity, a partially parallel processing based encoding process and encoder architecture are proposed.

Improving the efficiency of the LDPC code-based McEliece cryptosystem through irregular codes

, 2013
We consider the framework of the McEliece cryptosystem based on LDPC codes, which is a promising post-quantum alternative to classical public key cryptosystems.
