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.

Coset‐based QC‐LDPC codes without small cycles
Electronics Letters, 2014 A simple and efficient search method based on the coset concept is proposed to construct (3, L ) quasi‐cyclic low‐density parity‐check (QC‐LDPC) codes without small cycles. Compared with the random search method, the chance to find large‐girth codes is remarkably increased for the new method.

Explicit constructions of Type-II QC LDPC codes with girth at least 6 [PDF]
, 2007 Type-II quasi-cyclic (QC) LDPC codes are constructed from combinations of weight-0, weight-1 and weight-2 circulant matrices. The structure of cycles of length 2n are investigated, and necessary and sufficient conditions for a type-II QC LDPC parity ...

Quasi-Cyclic Asymptotically Regular LDPC Codes
, 2010 Families of "asymptotically regular" LDPC block code ensembles can be formed by terminating (J,K)-regular protograph-based LDPC convolutional codes. By varying the termination length, we obtain a large selection of LDPC block code ensembles with varying ...

Type-II QC-LDPC Codes From Multiplicative Subgroup of Prime Field
IEEE Access, 2020 A quasi-cyclic (QC) low-density parity-check (LDPC) code is called type-II, if the maximum weight over all circulants appearing in the parity-check matrix has the value of two. On the basis of multiplicative subgroup analysis for the prime field, a novel

Novel construction of QC-LDPC codes with modified 2-D GRS codes
Tongxin xuebao, 2015 The construction method for QC-LDPC (quasi-cyclic low density parity-check) code with modified two-dimensional generalized reed-solomon (2-D GRS) code is proposed using the generator polynomial of GRS code,so thus the constructed code can have better ...

A Class of Quantum LDPC Codes Constructed From Finite Geometries
, 2008 Low-density parity check (LDPC) codes are a significant class of classical codes with many applications. Several good LDPC codes have been constructed using random, algebraic, and finite geometries approaches, with containing cycles of length at least ...
