Symmetric Image Encryption Algorithm using 3D Rossler System

Abstract

Recently a lot of research has been done in the field of image encryption using chaotic maps. In this paper, we propose a new symmetric block cipher algorithm using the 3D Rossler system. The algorithm utilizes the approach used by Mohamed Amin et al. [Commun. Nonlinear Sci. Numer. Simulat, 15, 3484-97, (2010)] and Vinod Patidar et al. [Commun Nonlinear Sci Numer Simulat, 14, 3056-3075, (2009)]. The merits of these algorithms such as the encryption structure and the diffusion scheme respectively are combined with an approach to split the key for the three dimensions to use for encryption of color (RGB) images. The experimentation results suggest an overall better performance of the algorithm.
