Estudio de mapeos caóticos discretos y su aplicación en criptografía
(2015-01)
"La seguridad de la información digital cada vez tiene más auge, debido al creciente uso de dispositivos móviles, además del incremento de operaciones realizadas a través de internet. Esto representa un gran reto ya que ...
Pseudo-random bit generator based on multim-modal mapsGenerador de bits pseudoaleatorios basados en mapas multimodales
(2015-06)
"The present invention is related with a computer-implemented method for generating a pseudo-random bit generator including the steps: a. Defining a multi-modal map by the equation: fβ=β(dr+1−x)(x−dr), x ∈ ℑr; b. Set the ...
Hyperchaotic encryption based on multi-scroll piecewise linear systems
(2015)
"A hyperchaotic multi-scroll piecewise linear system in R4 is binarized to generate a pseudo-random sequence which encrypt a grayscale image via symmetric-key algorithm. The sequence is analyzed throughout statistical tests ...
Pseudo-random bit generator based on lag time series
(2014)
"In this paper, we present a pseudo-random bit generator (PRBG) based on two lag time series of the logistic map using positive and negative values in the bifurcation parameter. In order to hidden the map used to build the ...
Pseudo-random bit generator based on multi-modal maps
(2015)
"In this work we present a pseudo-random Bit Generator via unidimensional multi-modal discrete dynamical systems calledk-modal maps. These multi-modal maps are based on the logistic map and are useful to yield pseudo-random ...
Difference map and its electronic circuit realization
(2013)
"In this paper we study the dynamical behavior of the one-dimensional discrete-time system, the so-called iterated map. Namely, a bimodal quadratic map is introduced which is obtained as an amplification of the difference ...
Electronic implementation of a dynamical network with nearly identical hybrid nodes via unstable dissipative systems
(Elsevier, 2019)
"This work addresses a circuit architecture for a dynamical network composed of a type of chaotic hybrid oscillator based on Unstable Dissipative Systems (UDS). Implementing that system reveals the possibility of selecting ...
