Witryna1 sty 2024 · In all the chaotic image encryption algorithms, 1D chaotic mapping has fewer parameters and variables, and its phase space trajectory is simpler than high-dimensional chaotic mapping. Therefore, chaotic mapping techniques, such as logistic mapping [8-13], are extensively used. Witryna24 lip 2024 · 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 increase the security and privacy needed by applying variable keys.
