Revisiting Algebraic Attacks on MinRank and on the Rank Decoding Problem
Magali Bardet, Pierre Briaud, Maxime Bros +2
The Rank Decoding problem (RD) is at the core of rank-based cryptography. This problem can also be seen as a structured version of MinRank, which is ubiquitous in multivariate cryp…

RQC revisited and more cryptanalysis for Rank-based Cryptography
Loïc Bidoux, Pierre Briaud, Maxime Bros +1
We propose two main contributions: first, we revisit the encryption scheme Rank Quasi-Cyclic (RQC) by introducing new efficient variations, in particular, a new class of codes, the…
