This paper investigates the issue of chaos-based image encryption. Based on the z-shaped fuzzy number, the exponential function, and the modulo operator, a 1-D chaotic map is constructed and studied. This map contains areas with constant chaotic behavior and high Lyapunov exponent values. A statis ...

In this work, a chaotification technique is proposed for increasing the complexity of chaotic maps. The technique consists of adding the remainder of multiple scalings of the map’s value for the next iteration, so that the most- and least-significant digits are combined. By appropriate parameter tun ...
