    • Matrix approach of an encryption system based on cellular automata and its numerical implementation 

      Murguía, José; Flores Eraña, Gustavo; Mejía Carlos, Marcela; Rosu Barbus, Haret-Codratian (2012)
      "The main components of an encryption system based on rule 90 cellular automata, i.e., two indexed families of permutations and a pseudorandom bit generator are implemented in a very xible way through a convenient matrix ...

    • Perceptual security of encrypted images based on wavelet scaling analysis 

      Vargas Olmos, Cecilia; Murguía, José; Ramírez Torres, Marco Tulio; Mejía Carlos, Marcela; Rosu Barbus, Haret-Codratian (2016)
      "The scaling behavior of the pixel fluctuations of encrypted images is evaluated by using the detrended fluctuation analysis based on wavelets, a modern technique that has been successfully used recently for a wide range ...

    • Two-dimensional DFA scaling analysis applied to encrypted images 

      Vargas Olmos, Cecilia; Murguía, José; Ramírez Torres, Marco Tulio; Mejía Carlos, Marcela; Rosu Barbus, Haret-Codratian; González-Aguilar, Hernán (2015)
      "The technique of detrended fluctuation analysis (DFA) has been widely used to unveil scaling properties of many different signals. In this paper, we determine scaling properties in the encrypted images by means of a ...
