A FRACTAL ENCRYPTION ALGORITHM PENG Hai, GUO Qing-ping 1,2 Computer Processing & Distributing Laboratory, Wuhan University of Technology

the Mandlebrot Set Fractal The Fractal geometry was set up by Mandelbrot at 1973. Here it is the famous Mandlbrot Set Fractal which generate by the follow Mandlbrot Set Equation. Zk+1 = Zk2 + C (Z0 = 0)

Famous Fractals The Sierpinski triangle The Sierpinski carpet

Fractal Dimension Dimension: m - edges numbers s - sub-triangles numbers Dimension: n=1 n=2 n=3 n=4
