This paper targets to search so-called good generators by doing a brief survey over the
generators developed in the history of pseudo-random number generators (PRNGs), verify …

Four chaotic maps are used herein as case study to design an embedded cryptosystem
based on a pseudo-random number generator (PRNG). The randomness of the sequences …

Chaos-based stream ciphers form a prospective class of data encryption techniques.
Usually, in chaos-based encryption schemes, the pseudo-random generators based on …

Recently, chaotic maps have been considered to design pseudorandom number generator
(PRNG). However, some chaotic maps present security disadvantages, such as low …

In last years, low-dimensional and high-dimensional chaotic systems have been
implemented in cryptography. The efficiency and performance of these nonlinear systems …

In this work, we propose a novel 3D chaotic map obtained by coupling the piecewise and
logistic maps. Showing excellent properties, like a high randomness, a high complexity and …

This paper proposes a color image encryption algorithm based on a cloud model Fibonacci
chaotic system, as well as a matrix convolution operation that can protect image content …

We show the usefulness of bifurcation diagrams to implement a pseudo-random number
generator (PRNG) based on chaotic maps. We provide details on the selection of the best …

Pseudorandom numbers are widely used in information encryption, spread spectrum
communication and other science and technology and engineering fields. Because chaos is …

In recent years, a chaotic system is considered as an important pseudo-random source to
pseudo-random number generators (PRNGs). This paper proposes a PRNG based on a …
