In this paper, we propose a new color image encryption technique using two multidimensional chaotic maps: a three dimensional chaotic map for the key expansion and a two dimensional chaotic map for the generation of two chaotic lookup tables. The experimental results demonstrate that the distributions of red, green and blue surfaces of the encrypted image have a random-like behavior. Simulations show also that the proposed encryption scheme is particularly suitable for high speed applications.
