Chaos-based diffusion for highly autocorrelated data in encryption algorithms

Journal Article
Ahmad, J., & Hwang, S. O. (2015)
Chaos-based diffusion for highly autocorrelated data in encryption algorithms. Nonlinear Dynamics, 82(4), 1839-1850. https://doi.org/10.1007/s11071-015-2281-0
In a single substitution box, the same regions (pixels) of an image are encrypted to one unique symbol. To reduce this type of autocorrelation in data, chaos has been extensiv...
