A QC-LDPC Code Based Digital Signature Algorithm

2018 International Conference on Networking and Network Applications (NaNA), 2018
CFS digital signature algorithm, which proposed in 2001, is the most important code based digital signature algorithm and can resist the known attack of quantum algorithms. But the efficiency of CFS is very low because of the extremely low signing speed and the large public key size. In this paper, a variation of CFS algorithm is presented.

Low Complexity Decoding Algorithm of QC-LDPC Code

2010 IEEE Asia-Pacific Services Computing Conference, 2010
Through the research on the decoding algorithm of low-density parity-check (LDPC) code, a low complexity decoding algorithm suitable for quasi-cyclic LDPC (QC-LDPC) code is proposed in this paper. The algorithm adopts layered decoding (LD), and the sub-minimum is replaced by the sum of an optimal correction factor and the minimum during the process of ...

Combinatorial optimization for improving QC LDPC codes performance

2013 IEEE International Symposium on Information Theory, 2013
Techniques for searching for good quasi-cyclic (QC) LDPC block codes of short and moderate lengths which are suitable for practical purposes are studied. To facilitate implementations only codes whose parity-check matrices having bidiagonal structure of their submatrices and consequently having low encoding complexity are considered.

A Network-Efficient Nonbinary QC-LDPC Decoder Architecture

IEEE Transactions on Circuits and Systems I: Regular Papers, 2012
Nonbinary low-density parity-check (LDPC) codes are of great interest due to their better performance cover binary ones when the code length is moderate. However, the cost of decoder implementation for these LDPC codes is still very high. In this paper, a low-complexity VLSI architecture for nonbinary LDPC decoders is presented.

QC-LDPC Code-Based Cryptosystems

2014
In this chapter, the use of QC-LDPC codes in public key cryptosystems inspired to the McEliece and Niederreiter systems is studied. Both the case in which the private and the public code are permutation equivalent and that in which such an equivalence is absent are considered.

Low power decoder design for QC-LDPC codes

Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010
This paper presents a low-power decoder design approach for generic quasi-cyclic low-density parity-check (QC-LDPC) codes based on the layered min-sum decoding algorithm. To reduce the energy consumption, a novel message length-shortening scheme is explored.

A Low Complexity-High Throughput QC-LDPC Encoder

IEEE Transactions on Signal Processing, 2014
This paper introduces hardware architectures for encoding Quasi-Cyclic Low-Density Parity Check (QC-LDPC) codes. The proposed encoders are based on appropriate factorization and subsequent compression of involved matrices by means of a novel technique, which exploits features of recursively-constructed QC-LDPC codes.

Efficient Decoding of QC-LDPC Codes Using GPUs

2011
In this work, we propose an efficient quasi-cyclic LDPC (QCLDPC) decoder simulatorwhich runs on graphics processing units(GPUs). We optimize the data structures of the messages used in the decoding process such that both the read and write processes can be performed in a highly parallel manner by the GPUs.
