On the matrix code of quadratic relationships for a Goppa code
Rocco Mora
In this article, we continue the analysis started in \cite{CMT23} for the matrix code of quadratic relationships associated with a Goppa code. We provide new sparse and low-rank el…

Polynomial time key-recovery attack on high rate random alternant codes
Magali Bardet, Rocco Mora, Jean-Pierre Tillich
A long standing open question is whether the distinguisher of high rate alternant codes or Goppa codes \cite{FGOPT11} can be turned into an algorithm recovering the algebraic struc…
