A Color Image Encryption Technique Based on Bit-Level Permutation and Alternate Logistic Maps
Journal of Intelligent Systems, 2019 The paper presents an approach to encrypt the color images using bit-level permutation and alternate logistic map. The proposed method initially segregates the color image into red, green, and blue channels, transposes the segregated channels from the ...

Robust Image Encryption Framework Leveraging Multi-Chaotic Map Synergy for Advanced Data Security [PDF]
International Journal of TelecommunicationsIn the field of data security, image encryption is a crucial technique created especially for protecting visual data from abuse and unwanted access. Digital images are more vulnerable to illegal inter-ception, duplication, and manipulation as they are ...

Closure measures for coarse-graining of the tent map
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2014 We quantify the relationship between the dynamics of a time-discrete dynamical system, the tent map T and its iterations Tm, and the induced dynamics at a symbolical level in information theoretical terms. The symbol dynamics, given by a binary string s of length m, is obtained by choosing a partition point α∈[0,1] and lumping together the points x∈[0 ...

Semi-conjugacies from the z-type map to the Tent map
四川大学学报. 自然科学版, 2017 This paper studies semi-conjugacies from the z-type map to the Tent map. Using the partition of the domain, and the encoding for unimodal maps, we present the explicit expressions of two non-monotone semi-onjugacies.

On the dynamics of skew tent maps
, 2017 In this paper we give an elementary treatment of the dynamics of skew tent maps. We divide the two-parameter space into six regions. Two of these regions are further subdivided into infinitely many regions. All of the regions are given explicitly. We find the attractor in each subregion, determine whether the attractor is a periodic orbit or is chaotic,

A novel image encryption/decryption scheme based on integrating multiple chaotic maps
AIP Advances, 2020 In this paper, a novel framework is presented for chaotic image encryption. The proposed method is based on integrating multiple chaotic maps (e.g., logistic, tent, quadratic, cubic, and Bernoulli) to generate more robust chaotic maps in order to ...

MathematicsChaotic maps are sources of randomness formed by a set of rules and chaotic variables. They have been incorporated into metaheuristics because they improve the balance of exploration and exploitation, and with this, they allow one to obtain better ...

A Novel Chaotic Interior Search Algorithm for Global Optimization and Feature Selection
Applied Artificial Intelligence, 2020 Interior Search Algorithm (ISA) is a recently proposed metaheuristic inspired by the beautification of objects and mirrors. However, similar to most of the metaheuristic algorithms, ISA also encounters two problems, i.e., entrapment in local optima and ...
