Cryptosystem Based on Induced Group Codes

open access: yesМоделирование и анализ информационных систем, 2016
The code C on a group G, induced by the code N on a subgroup H, has the property that for decoding the code C one can use the decoder for the code N.

Decoding the Tensor Product of MLD Codes and Applications for Code Cryptosystems

open access: yesМоделирование и анализ информационных систем, 2017
For the practical application of code cryptosystems such as McEliece, it is necessary that the code used in the cryptosystem should have a fast decoding algorithm.

A Centralized Key Management Scheme Based on McEliece PKC for Space Network

open access: yesIEEE Access, 2020
Constrained by the limited resource, high-latency and high bit error rate, the existing group key management schemes for the space network are inefficient. To solve this problem, we proposed a centralized and identity-based key management scheme by using

Selecting parameters for secure McEliece-based cryptosystems [PDF]

open access: yesInternational Journal of Information Security, 2012
In 1994, Shor showed that quantum computers will be able to break cryptosystems based on the problems of integer factorization and the discrete logarithm, for example, RSA or ECC. Code-based cryptosystems are promising alternatives to public-key schemes built on these problems, and they are believed to be secure against quantum computer attacks.

Cryptanalysis of McEliece’s Public-Key Cryptosystem [PDF]

open access: yes, 2007
An approach is proposed for the cryptanalysis of the well-known version of McEliece's public-key cryptosystem that is based on a new iterative optimization algorithm for decoding an arbitrary linear code. The algorithm provides guaranteed correction of all error patterns with Hamming weight less than d/2, where d is the minimum distance of the code ...

Code-Based Cryptography With Generalized Concatenated Codes for Restricted Error Values

open access: yesIEEE Open Journal of the Communications Society, 2022
Code-based cryptosystems are promising candidates for post-quantum cryptography. Recently, generalized concatenated codes over Gaussian and Eisenstein integers were proposed for those systems. For a channel model with errors of restricted weight, those q-

Strengthening McEliece Cryptosystem [PDF]

open access: yes, 2000
McEliece cryptosystem is a public-key cryptosystem based on error-correcting codes. It constitutes one of the few alternatives to cryptosystems relying on number theory. We present a modification of the McEliece cryptosystem which strengthens its security without increasing the size of the public key.

Tensor-based trapdoors for CVP and their application to public key cryptography

open access: yes, 1999
We propose two trapdoors for the Closest-Vector-Problem in lattices (CVP) related to the lattice tensor product.

Joint QKD-Post-Quantum Cryptosystems

open access: yesIEEE 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 ...
