Image encryption using a 3D modular hybrid chaotic system and CRC key generator

With the development of social networks, the demand for information security is increasing day by day, and as images are one of the most commonly used formats, this paper introduces a novel method for encrypting images using a new 3D modular hybrid chaotic map with two control parameters. The significance of chaotic maps in secure information transformation algorithms lies in the sensitivity of digital images to minor pixel alterations and the high degree of similarity between neighboring pixels. Another aspect of cryptographic algorithms is the creation of a key space that is sensitive to input images. As such, a primary objective in this procedure is to incorporate a cyclic redundancy check and the discrete framelet transform to generate an optimal key space. Finally, aforementioned tools lead to the implementation of a secure encryption algorithm based on cellular automata and simulation results severely demonstrate robustness and resistance of the proposed scheme against data loss attacks.
