Abstract

In this paper, a new image encryption scheme based on 2D generalized sawtooth map is proposed. Utilizing the chaotic
nature of 2D generalized sawtooth maps, image pixel positions are scrambled and image pixels gray values are changed
to encrypt the plain-images. Experimental results have been carried out with detailed analysis to demonstrate that the
proposed image encryption scheme possesses large key space to resist brute-force attack and possesses good statistical
properties to frustrate statistical analysis attacks.
