Advanced Functional Materials, EarlyView.Resonant standing waves generate large‐area lattices of liquid‐crystal topological defects that are permanently encoded into polymer coatings by photopolymerization. The preserved director architecture produces thermally reconfigurable surface topographies while maintaining programmable optical functionality, demonstrating a scalable strategy for ...

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 ...

Modified chaotic shift keying using indirect coupled chaotic synchronization for secure digital communication [PDF]
, 2010 In this paper, a modified chaotic shift keying method is proposed to transmit digital bits securely over a communication channel. The scheme is based upon encrypting the digital bits 0 and 1 into infinite levels by applying the keystream such that there

Identification of chaos in fractional chaotic map
Advances in Difference Equations, 2020 This paper utilizes the 0–1 test algorithm to identify chaos in a fractional chaotic map. A fractional Burgers map is proposed by means of the Caputo-like delta difference operator. The bifurcation diagrams, phase trajectories and 0–1 test results of the

Chaotic block cryptosystem using high precision approaches to tent map [PDF]
, 2011 This paper presents the implementation and evaluation of a block cryptosystem based in chaotic maps. The noise function used in this cryptosystem is an approximation to the chaotic tent map, and for this reason, it is named pseudo chaotic tent map (PCT ...

CHAOTIC DIFFUSION IN MULTIDIMENSIONAL CONSERVATIVE MAPS
International Journal of Bifurcation and Chaos, 2012 In the present paper, we provide results and discussions concerning the processes that lead to local and global chaotic diffusion in the phase space of multidimensional conservative systems. We investigate and provide a measure of the extent of the domain over which diffusion may occur.
