Image encryption using shuffled Arnold map and multiple values manipulations

Abstract

In this paper, we present an image encryption scheme based on improved Arnold map. The improvement in the Arnold map includes a Divide & Rotate operation and pixels shuffling. The obtained shuffled Arnold map shows better results in terms of performance and speed. The proposed encryption scheme applies a preprocessing procedure on the plain image. We use the Shuffled Arnold map in the confusion process for only one round. For the diffusion process, we execute a Forward & Backward process to apply an integer-level values manipulation. The evaluation of the proposed method shows high sensitivity and resistance against common attacks.
