Linear codes arising from geometrical operation
Antonio Jesús Lorite López, Daniel Camazón Portela, Juan Antonio López Ramos
We construct linear codes over the finite field Fq from arbitrary simplicial complexes, establishing a connection between topological properties and fundamental coding parameters.…
A generalization of Burmester-Desmedt GKE based on a non-abelian finite group action
Daniel Camazón Portela, Ãlvaro Otero Sánchez, Juan Antonio López Ramos
The advent of large-scale quantum computers implies that our existing public-key cryptography infrastructure has become insecure. That means that the privacy of many mobile applica…
Semigroup action based on skew polynomial evaluation with applications to Cryptography
Daniel Camazón-Portela, Juan Antonio López-Ramos
Through this work we introduce an action of the skew polynomial ring over based on its polynomial valuation and the concept…
The Chow ring of a sequence of point and rational curve blow-ups
Daniel Camazón Portela
Given a sequence of point and rational curve blow-ups blow-ups of smooth dimensional projective varieties defined over an algebraically closed field , $Z_{s…
