Witryna1 wrz 2012 · The security of this encryption algorithm depends on the initial conditions of 1D and 2D logistic chaotic maps, which include the front and latter pixel sum of plain image. However, this scheme is not secure enough because the front half and latter half pixel sum can be known to the attacker. Witryna20 wrz 2024 · Logistic Sine Map Based Image Encryption Abstract: In this paper, an image encryption algorithm is proposed in which first the image pixels are shuffled … personal home care lynchburg va
An image encryption method based on logistic chaotic mapping …
Witryna1 mar 2024 · In order to improve the problems of small key space and poor security when the one-dimension logistic chaotic map is applied in image encryption, we propose a modified Logistic chaotic map. Based on the modified Logistic chaotic map, a new image encryption algorithm is introduced. Witryna13 kwi 2024 · An image encryption model is presented in this paper. The model uses two-dimensional Brownian Motion as a source of confusion and diffusion in image pixels. Shuffling of image pixels is done using Intertwining Logistic Map due to its desirable chaotic properties. The properties of Brownian motion helps to ensure key sensitivity. … Witryna12 cze 2014 · Logistic Map [ 27, 28] is a polynomial mapping of degree 2 that exhibits chaotic behavior. The Logistic Map equation is given by When the variable is given different value, ranging from 2 to 4, through formula ( 1 ), we could plot Lyapunov exponent of Logistic Map as well. That is shown in Figure 2. Figure 2 personal holding company form
