Chaotic Image Cryptography Systems: A Review

Abstract

In recent decades, image encryption has been a popular and important field of research. The image encryption techniques have been studied thoroughly to ensure the safety of digital images on transmission through the networks. A large range of algorithms for chaotic-based cryptographic systems has been suggested and submitted to enhance the efficiency of the encryption methods. The chaotic map is one technique to guarantee security. The benefits of chaotic image encryption include the fact that it is simple to implement; it has a faster encryption speed, and it is powerful against attacks. Due to their extreme sensitivity to initial conditions, unpredictability, and random-like behaviours, many image encryption systems using chaotic maps have been proposed. This study paper presents a scientific review of many types of researches during the (2014-2020) years that used chaotic with its various types (one-dimensional, multi-dimensional, or hyper-chaotic) to process the digital images in the encryption stage or the scrambling phase. Furthermore, it presents a future reading of researches that has a wider role in developing the cryptography field by improving the efficiency of Algorithms where using a chaotic map with other methods gives better results than using chaotic alone in scrambling and encryption methods.

Hyperchaotic technology-based efficient image encryption algorithm an overview.

“…To address this issue, researchers have concentrated on approaches that address both confusion and criteria for diffusion, numerous hyper chaos-based algorithms have been presented recently and have gained a lot of support from academics [1]. The image encryption which is based on chaos systems suits high-security encryption due to the properties of chaos systems that are inherent to them, such as sensitivity to beginning value and randomness Nonlinear deterministic dynamical systems that produce pseudorandom sequences are known as chaotic systems [6] [15]. Because of their distinctive characteristics, chaos theories are viewed as being advantageous to multimedia encryption and enhancing the cryptosystem resistance to statistical attacks and the attributes are [5].…”

Image encryption based on combined between linear feedback shift registers and 3D chaotic maps

“…Particularly in times of war, the confidentiality and security of transmitted information play an essential role in success [3]. Encrypting is an effective way to protect an image's data before sending it to the receiver [2], [4]. The main purpose of the image encryption process is to transform it into another form so that no one can know its content without owning the original key [5].…”

Hyper Coupled Map Lattices for Hiding Multiple Images

“…Te confdentiality of digital image can be maintained by data encryption [17,18]. A variety of techniques for encrypting images include cryptography [19,20], watermarking [21,22], and steganography [23,24].…”
