Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 The existing reversible data hiding methods in encrypted domain separate image encryption from information embedding and do not make full use of the redundant space in the process of image encryption. In order to improve the performance of reversible data hiding by using the technical characteristics of image encryption, a reversible data hiding method

Post‐Quantum Secure Password‐Authenticated Key Exchange Based on Ouroboros
Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 Password‐authenticated key exchange (PAKE) protocols play an important role in cryptography. Most of PAKEs are based on the Diffie–Hellman key exchange protocols or RSA encryption schemes, but their security is threatened by quantum computers. In this study, we propose the first code‐based PAKE protocol based on Ouroboros, which is a code‐based key ...

Generalized Concatenated Codes over Gaussian and Eisenstein Integers for Code-Based Cryptography
Cryptography, 2021 The code-based McEliece and Niederreiter cryptosystems are promising candidates for post-quantum public-key encryption. Recently, q-ary concatenated codes over Gaussian integers were proposed for the McEliece cryptosystem, together with the one-Mannheim ...

Compact McEliece keys based on quasi-dyadic Srivastava codes
Journal of Mathematical Cryptology, 2012 The McEliece cryptosystem is one of the few systems to be considered secure against attacks by Quantum computers. The original scheme is built upon Goppa codes and produces very large keys, hence recent research has focused mainly on trying to reduce the

Decoding the Tensor Product of MLD Codes and Applications for Code Cryptosystems
Моделирование 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 Key-Recovery Side-Channel Attack on Classic McEliece Implementations
Transactions on Cryptographic Hardware and Embedded Systems, 2022 In this paper, we propose the first key-recovery side-channel attack on Classic McEliece, a KEM finalist in the NIST Post-quantum Cryptography Standardization Project.

The Support Splitting Algorithm for Induced Codes
Моделирование и анализ информационных систем, 2018 In the paper, the analysis of the stability of the McEliece-type cryptosystem on induced codes for key attacks is examined. In particular, a model is considered when the automorphism group is trivial for the base code C, on the basis of which the induced
