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 ...

McNie: A code-based public-key cryptosystem
CoRR, 2018 In this paper, we suggest a code-based public key encryption scheme, called McNie. McNie is a hybrid version of the McEliece and Niederreiter cryptosystems and its security is reduced to the hard problem of syndrome decoding. The public key involves a random generator matrix which is also used to mask the code used in the secret key.

A Solidity implementation of TAVS
Frontiers in Blockchain, 2023 We present a Solidity smart contract implementation of the TAVS e-voting protocol. The Two Authorities Electronic Voting Scheme (TAVS) is a voting scheme that achieves universal verifiability with a reduced time-complexity both for the elector and the ...

A Flexible NTT-Based Multiplier for Post-Quantum Cryptography
IEEE Access, 2023 In this work an NTT-based (Number Theoretic Transform) multiplier for code-based Post-Quantum Cryptography (PQC) is presented, supporting Quasi Cyclic Low/Moderate-Density Parity-Check (QC LDPC/MDPC) codes.

Scaling efficient code-based cryptosystems for embedded platforms [PDF]
Journal of Cryptographic Engineering, 2014 We describe a family of highly efficient codes for cryptographic purposes and dedicated algorithms for their manipulation. Our proposal is especially tailored for highly constrained platforms, and surpasses certain conventional and post-quantum proposals (like RSA and NTRU, respectively) according to most if not all efficiency metrics.

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).

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

Security of generalised Reed–Solomon code‐based cryptosystems
IET Information Security, 2019 In this study, the authors elaborate on a recently proposed variant of the public‐key McEliece and Niederreiter cryptosystems using generalised Reed–Solomon (GRS) codes as private codes. The use of these codes brings known advantages in terms of public key size, but particular care is needed in the choice of parameters not to endanger the system ...

McEliece public key cryptosystem attack algorithm based on enumeration error vector
Tongxin xuebao, 2014 The research on the security of McEliece (M) public key cryptosystem was presented. The Hamming weight of error vector is less than the code length, and M public key cryptosystem based on Goppa code possesses low weight public code words. Considering the
