A Modified pqsigRM: RM Code-Based Signature Scheme
Code-based cryptography Courtois Finiasz
2019/6/12
We propose a novel signature scheme based on a modified Reed--Muller (RM) code, which reduces the signing complexity and key size compared to existing code-based signature schemes. This cheme is calle...
Evaluation of Code-based Signature Schemes
post-quantum cryptography code-based cryptography signature scheme
2019/5/23
Code-based cryptographic schemes recently raised to prominence as quantum-safe alternatives to the currently employed number-theoretic constructions, which do not resist quantum attacks. In this artic...

Code-based cryptography zero-knowledge range arguments
2019/5/21
Code-based cryptography has a long history but did suffer from periods of slow development. The field has recently attracted a lot of attention as one of the major branches of post-quantum cryptograph...
A Post-Quantum UC-Commitment Scheme in the Global Random Oracle Model from Code-Based Assumptions
Commitment Scheme Universal Composability
2019/2/27
In this work, we propose the first post-quantum UC-commitment scheme in the Global Random Oracle Model, where only one non-programmable random oracle is available. The security of our proposal is base...
Cryptanalysis of a New Code-based Signature Scheme with Shorter Public Key in PKC 2019
RQCS digital signatures cryptanalysis
2019/2/27
Song, Huang, Mu, and Wu proposed a new code-based signature scheme, the Rank Quasi-Cyclic Signature (RQCS) scheme (PKC 2019, Cryptology ePrint Archive 2019/053), which is based on an IND-CCA2 KEM sche...

2018/12/20
In 2012, Lyubashevsky introduced a new framework for building lattice-based signature schemes without resorting to any trapdoor (such as GPV [6] or NTRU [8]). The idea is to sample a set of short latt...

2018/12/19
A repair of the Faure-Loidreau (FL) public-key code-based cryptosystem is proposed.The FL cryptosystem is based on the hardness of list decoding Gabidulin codes which are special rank-metric codes. We...

With the fast development of quantum computation, code based cryptography arises public concern as a candidate of post quantum cryptography. However, the large key-size becomes a main drawback such th...
We present here Wave the first ``hash-and-sign'' code-based signature scheme which strictly follows the GPV strategy [GPV08]. It uses the family of ternary generalized (U,U+V)(U,U+V) codes. We prove t...
