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 ...

Complete and Improved FPGA Implementation of Classic McEliece
Transactions on Cryptographic Hardware and Embedded Systems, 2022 We present the first specification-compliant constant-time FPGA implementation of the Classic McEliece cryptosystem from the third-round of NIST’s Post-Quantum Cryptography standardization process.

Quantum approximate optimization of the coset leader problem for binary linear codes
Computational and Mathematical Methods, Volume 3, Issue 6, November 2021., 2021 Abstract The security of a broad family of coding‐based cryptographic techniques relies on the hardness of the Syndrome Decoding Problem (SDP). In this problem, the aim is to find a word with a given syndrome and of Hamming weight smaller than a prefixed bound.

Quantum Election Protocol Based on Quantum Public Key Cryptosystem
Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021 There is no quantum election protocol that can fulfil the eight requirements of an electronic election protocol, i.e., completeness, robustness, privacy, legality, unreusability, fairness, verifiability, and receipt‐freeness. To address this issue, we employ the general construction of quantum digital signature and quantum public key encryption, in ...

Cryptanalysis of the Original McEliece Cryptosystem [PDF]
, 2000 The class of public-key cryptosystems based on error-correcting codes is one of the few alternatives to the common algorithms based on number theory. We here present an attack against these systems which actually consists of a new probabilistic algorithm for finding minimum-weight words in any large linear code.

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 ...

Single Trace Analysis against HyMES by Exploitation of Joint Distributions of Leakages
Applied Sciences, 2020 Beginning with the proposal of the McEliece cryptosystem in 1978, code-based cryptography has positioned itself as one of main categories in post-quantum cryptography (PQC).
