In this paper, a new four-dimensional hyperchaotic system that has better unpredictability,
more complex dynamic behavior, and a larger key space is proposed. The initial chaos …

This paper presents a novel approach for encrypting images using a Sudoku as its
encryption key. This algorithm uses both symmetric and asymmetric key cryptography. It …

Currently, images are very important with the rapid growth of communication networks.
Therefore, image encryption is a process to provide security for private information and …

S-box is one of the most significant structures used to construct encryption that is strong and
resistant to attacks in encryption algorithms. The new 4D-hyper chaotic system and …

Plethora of image encryption schemes exist in literature based on the construct of magic
square for realizing the purpose of image obfuscation. This magic square carries out the …

In order to prevent unwanted access to sensitive data by unauthorized individuals, color
images are encoded. Because chaotic-deoxyribonucleic acid (chaotic-DNA) encoding can …

Powerful cryptographic systems require a qualified random number generator. This research
purposes to provide a comprehensive comparative analysis done on several of the well …

Digital image security has become a major concern due to open networks and Internet data
sharing. Many image encryption algorithms have been introduced recently for securely …

In this paper, a proposed novel seven dimensions (7D) hyperchaotic system with twelve
positive parameters is presented. A chaotic behavior for the proposed system is proved …

This research paper introduces a novel encryption algorithm that utilizes a hyper six-
dimensional chaotic system to enhance image security. The algorithm incorporates …
