Research on color image encryption approach based on chaotic Duffing map

Abstract

In this study, we propose a novel image encryption approach that utilizes the chaotic dynamics of the Duffing map and Moore-penrose pseudo inverse to obscure images. Chaotic maps have been widely used in the field of image encryption due to their sensitive dependence on initial conditions, enabling them a suitable candidate for generating pseudo-random sequences that can be used for encryption tasks. The Duffing map, known for its complex nonlinear behavior, is highly preferred for developing robust and secure encryption schemes. The proposed approach aims to develop a balance between encryption efficiency and cryptographic security while maintaining a straightforward implementation. The analytical results and comparison of suggested approach with some existing approaches exhibit that it is a robust and secure method for real-time image encryption.
