Image Cryptography Scheme Based on Improvement Chaos Logistic Function, Chaos Arnold Cat Map and Gingerbread Man Process

Recently, information security has emerged as a crucial aspect of information technology and communication considering the Internet's proliferation. The development of image cryptography emerged as a method to enhance the confidentiality of communication. In order to achieve these aims, a framework comprising three primary phases has been developed for the purpose of image cryptography. During the first phase, a fresh key generator was developed, incorporating a substantial degree of randomness by utilizing several chaotic maps and the suggested Improvement Chaos Logistic function (ICLF). In the second phase, the proposed method involves the introduction of a confusion process. This phase entails the sorting of the key generator in ascending order, followed by the permutation of the image pixels depending on the sorting key. Finally, the diffusion phase is described, which involves the utilization of the Gingerbread Man Method (GGM), Arnold Cat Map (ACM) transform, and XOR operation. Based on the findings, it has been confirmed that the suggested image cryptography method has a better result in the field of cryptography when compared with existing methods.
