A generalization of Burmester-Desmedt GKE based on a non-abelian finite group action
Daniel Camazón Portela, Álvaro 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…
On the solutions of linear systems over additively idempotent semirings
Álvaro Otero Sánchez, Daniel Camazón, Juan Antonio López Ramos
The aim of this article is to solve the system where , and is an unknown vector of size , being an additively idempot…
Cryptoanalysis of a key exchange protocol based on a congruence-simple semiring action
Otero Sanchez Alvaro, Lopez Ramos Juan Antonio
We show that a previously introduced key exchange based on a congruence-simple semiring action is not secure by providing an attack that reveals the shared key from the distributed…
Error-Correcting Codes on Projective Bundles over Deligne-Lusztig varieties
Daniel Camazón Portela, Juan Antonio López Ramos
The aim of this article is to give lower bounds on the parameters of algebraic geometric error-correcting codes constructed from projective bundles over Deligne--Lusztig surfaces.…
