We present new theoretical results on the fractional Brownian motion, including different definitions (and their relationships) of the stochastic integral with respect to this process ... Webthe planar Brownian motion, for which it is not possible to apply directly the ergodic theorem. Nevertheless, for the fractional Brownian motion, we shall see that the study of the windings is much more difficult because the integral (1.1) is not a time-changed fractional Brownian motion. 2.

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. Finally, a …
