Extensions of root-based attacks against PLWE via isomorphisms of rings

Iván Blanco-Chacón, Rodrigo Martín Sánchez-Ledesma, Raúl Durán Díaz

The paper investigates extensions of root‑based attacks on the Polynomial Learning With Errors (PLWE) problem by constructing explicit isomorphisms between vulnerable polynomial ri…

A blueprint for constructing 3-pass AKE protocols under commitment-based models

Rodrigo Martín Sánchez-Ledesma

The commitment-based AKE model provides a formal security framework for key exchange protocols that avoid long-term cryptographic material, achieving authentication through a final…

A Commitment-based Authentication model for Key Exchange protocols

Rodrigo Martín Sánchez-Ledesma, David Domingo Martín, Iván Blanco Chacón +1

In this work we construct an alternative model for Authenticated Key Exchange, intended to build a theoretic security framework for protocols whose characteristics may not always c…

Fast Multiplication and the PLWE-RLWE Equivalence for an Infinite Family of Maximal Real Subfields of Cyclotomic Fields

Joonas Ahola, Iván Blanco-Chacón, Wilmar Bolaños +3

We prove the equivalence between the Ring Learning With Errors (RLWE) and the Polynomial Learning With Errors (PLWE) problems for the maximal totally real subfield of the
