Images encryption using AES and variable permutations
V. M. Silva-García, R. Flores-Carapia, C. Rentería-Máarquez +2
This work proposes a different procedure to encrypt images of 256 grey levels and colour, using the symmetric system Advanced Encryption Standard with a variable permutation in the…
Affine cartesian codes
Hiram H. Lopez, Carlos Renteria, Rafael H. Villarreal
We compute the basic parameters (dimension, length, minimum distance) of affine evaluation codes defined on a cartesian product of finite sets. Given a sequence of positive integer…
Algebraic methods for parameterized codes and invariants of vanishing ideals over finite fields
C. Renteria, A. Simis, R. H. Villarreal
Let K be a finite field with q elements and let X be a subset of a projective space P^{s-1}, over the field K, which is parameterized by Laurent monomials. Let I(X) be the vanishin…
Systems with the integer rounding property in normal monomial subrings
Luis A. Dupont, Carlos Renteria-Marquez, Rafael H. Villarreal
Let C be a clutter and let A be its incidence matrix. If the linear system x>=0;xA<=1 has the integer rounding property, we give a description of the canonical module and the a-inv…
