We describe a variation of the Schnorr-Lyubashevsky approach to devising signature schemes that is adapted to rank based cryptography. This new approach enables us to obtain a randomization of the sig...
On a Rank-Metric Code-Based Cryptosystem with Small Key Size
code-based cryptography rank-metric codes interleaving
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...
DRANKULA: a McEliece-like rank metric based cryptosystem implementation
Code-based cryptography Public key cryptography Cryptosystem
2018/8/28
We present and analyze the performance of DRANKULA, a McEliece-like cryptosystem implementation using \textit{rank metric} instead of Hamming distance. Namely, we use the scheme proposed by Loidreau i...
Revocable Identity-based Encryption from Codes with Rank Metric
Code-based Cryptography Identity-based Encryption Key Revocation
2018/5/2
In this paper, we present an identity-based encryption scheme from codes with efficient key revocation. Recently, in Crypto 2017, Gaborit et al. proposed a first identity-based encryption scheme from ...
A polynomial attack on a NIST proposal: RankSign, a code-based signature in rank metric
public-key cryptography NIST
2018/4/17
RankSign is a code-based signature scheme proposed to the NIST competition for post-quantum cryptography [AGHRZ17]. It is based on the rank metric and enjoys remarkably small key sizes, about 10KBytes...
Identity-based Encryption from Codes with Rank Metric, Full Version
Code-based cryptography Rank metric IBE
2017/6/6
Code-based cryptography has a long history, almost as long as the history of public-key encryption (PKE). While we can construct almost all primitives from codes such as PKE, signature, group signatur...
A new rank metric codes based encryption scheme
McEliece encryption scheme code based cryptography
2017/3/13
We design a new McEliece-like rank metric based encryption scheme from Gabidulin codes. We explain why it is not affected by the invariant subspace attacks also known as Overbeck's attacks. The idea o...
RankSign : an efficient signature algorithm based on the rank metric
code based crypto rank metric
2014/3/6
In this paper we propose a new approach to code-based signatures that makes use in particular of rank metric codes. When the classical approach consists in finding the unique preimage of a syndrome th...
