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 ...

A Class of Quadratic Polynomial Chaotic Maps and its Application in Cryptography
IEEE Access, 2019 At present, the probability density of most chaotic systems is unknown, and the statistical characteristics of chaotic sequences cannot be described by the probability density of chaotic maps. This paper constructs a class of quadratic polynomial chaotic

A novel 1D powered Chebyshev quadratic map-based image encryption using dynamic permutation-diffusion [PDF]
Scientific ReportsChaotic maps have gained significant attention in image encryption systems due to their intrinsic features, including sensitive dependence on initial conditions, non-linear dynamics, high entropy, and ergodicity. These properties enable the generation of

Memristor-type chaotic mapping [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2022 In this letter, a compact memristor structure unit is applied for constructing the discrete chaotic system and, consequently, a memristor-type chaotic mapping is designed. Two independent system parameters are proven to be partial and total amplitude controllers. Meanwhile, the internal memristor parameter returns the map a typical bifurcation. Finally,

Lyapunov Exponent Enhancement in Chaotic Maps with Uniform Distribution Modulo One Transformation
Chaos Theory and Applications, 2022 Most of the chaotic maps are not suitable for chaos-based cryptosystems due to their narrow chaotic parameter range and lacking of strong unpredictability.
