Efficient and Scalable FPGA-Oriented Design of QC-LDPC Bit-Flipping Decoders for Post-Quantum Cryptography

IEEE Access, 2020
Considering code-based cryptography, quasi-cyclic low-density parity-check (QC-LDPC) codes are foreseen as one of the few solutions to design post-quantum cryptosystems.

Circulant Arrays on Cyclic Subgroups of Finite Fields: Rank Analysis and Construction of Quasi-Cyclic LDPC Codes

, 2010
This paper consists of three parts. The first part presents a large class of new binary quasi-cyclic (QC)-LDPC codes with girth of at least 6 whose parity-check matrices are constructed based on cyclic subgroups of finite fields.

Synthetic Aperture Radar (SAR)‐Based Evaluation of Tropical Cyclone Wind Profiles and a Theory‐Based Radius of Maximum Wind Estimation

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Accurate wind profiles and radius of maximum wind (Rmax ${R}_{\max }$) are critical for reconstructing realistic tropical cyclones (TCs) to predict extreme ocean conditions, including storm surges and waves. Leveraging the expanding Synthetic Aperture Radar (SAR) database, we conducted the first comprehensive evaluation of commonly used TC ...

Joint QKD-Post-Quantum Cryptosystems

IEEE Access, 2020
To extend the transmission distance and/or improve secret-key rate of QKD protocols, we propose to employ the joint QKD-post-quantum cryptosystems in which QKD is used for raw-key transmission while the post-quantum cryptography (PQC) subsystem to ...

Research on LDPC Coding for Free Space Optical Communication with Modified Bessel-Gaussian Beams Based on K-distribution

MATEC Web of Conferences, 2018
We investigate the performance of low-density parity-check (LDPC) coding for free space optical communication (FSO) with modified Bessel-Gaussian (MBG) beams based on K-distribution.

On the girth of Tanner (3,7) quasi-cyclic LDPC codes [PDF]

Transactions on Combinatorics, 2012
S. Kim, et al, have been analyzed the girth of some algebraically structured quasi-cyclic (QC) low-density parity-check (LDPC) codes, i.e. Tanner (3,5) of length 5p, where p is a prime of the form 15m+1. In this paper, by extension this method to Tanner (
