A Cipher Based on Prefix Codes
Sensors, 2021 A prefix code, a P-code, is a code where no codeword is a prefix of another codeword. In this paper, a symmetric cipher based on prefix codes is proposed. The simplicity of the design makes this cipher usable for Internet of Things applications. Our goal

An Efficient Public Key Encryption Scheme Based on QC-MDPC Lattices
IEEE Access, 2017 In this paper, we introduce a new family of lattices, namely QC-MDPC lattices, which are a special case of LDPC lattices, and an improved bit flipping algorithm for decoding of these lattices. Encoding and decoding implementations of QC-MDPC lattices are

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 ...

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 ...

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 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.

An Algebraic Attack on Rank Metric Code-Based Cryptosystems [PDF]
, 2020 The Rank metric decoding problem is the main problem considered in cryptography based on codes in the rank metric. Very efficient schemes based on this problem or quasi-cyclic versions of it have been proposed recently, such as those in the submissions ROLLO and RQC currently at the second round of the NIST Post-Quantum Cryptography Standardization ...

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).

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.
