Chaos

Strong and weak regions of Logistic Map, Logistic-Tent system, Logistic-Sine system and Tent-Sine system have been identified using using 0-1 test and three state test (3ST). This’ll encourage stronger testing practices, making cryptosystems more secure.

This paper discusses how COVID-19 has changed the landscape of multimedia consumption and resulted in an imperative need for better and faster selective encryption techniques and presents a survey of the most recent advances.

Novel selective image encryption technique based on 4-D hyperchaos, improved 1-D Logistic map, and the square wave space filling curve (SFC) is proposed that outperforms existing schemes.

A domain-flexible and selective image encryption scheme based on genetic algorithm, non-linear chaotic map, square-wave diffusion and orthogonal polynomials transformation is proposed. Extensive experiments were used to demonstrate efficiency and practicality.

A new selective image encryption technique based on hyperchaos, random artificial image, orthogonal polynomials transformation and dynamic permutation matrix using Lower Upper (LU) Decomposition is proposed, that outperforms existing approaches.
