During the recent years several chaotic image encryption algorithms based on One Dimensional (1-D) have been proposed, but the drawbacks of small key space, low speed and low security in 1-D chaotic cryptosystems are obvious. This paper proposes a new image encryption technique based on 1-D and 2-D chaotic maps which provide more security and big key space. The 1-D chaotic system is induced from a mathematical combination between the logistic map and the cubic chaotic map.
