Improved Lorenz chaotic map with dynamic zig-zag pattern for high-security digital image encryption

This study proposes a secure image encryption framework based on an improved Lorenz chaotic map combined with a dynamic zig-zag permutation strategy. The improved chaotic mapping introduces dynamic perturbations to increase the complexity of chaotic trajectories and expand the key space, while the dynamic zig-zag trave...
