“…The generated key-streams have no dependence with respect to the characteristics of the plain-image that may lead to the non-resistance to known/chosen plain-text attacks. [22] (A new chaos-based image encryption system), the proposed scheme is based on a modified version of 2D cat map, permutation at a bit level and confusion-diffusion architecture. The proposed crypto-system belongs to the category of block ciphers with CBC mode.…”

The design of image encryption schemes that make a good compromise between sufficient level of security and execution time is one of the main directions of research, due to their ever-increasing use in real-time Internet image encryption and transmission applications. For such task, a variety of mathematical and biological strategies are investigated in the literature as chaos theory, cellular automata and DNA computing. The intend of this paper is to present a complete study of some recent and prevalent proposed works in the literature, this study covers the analysis of each work by giving its advantages and limitations in terms of security level and execution time. We believe that our study within this contribution will help in the design of new secure crypto-systems for image encryption.

“…It is seen that the new cryptosystem is robust, faster, simpler and more secured in comparison with Ref. [2] and other chaos-based cryptosystems [1][2][3][4][5]9]. A statistical investigation is also carried out to ensure that the proposed encryption scheme is free from any brute force attack.…”

We study the encryption and decryption processes of color images using the synchronization of polarization dynamics in a freerunning vertical-cavity surface-emitting laser (VCSEL). Here, we consider a bidirectional master-slave configuration or two-way coupling with two VCSELs. The latter are shown to exhibit hyperchaos and synchronization with a high level of similarity between their emission characteristics. The coupled VCSELs are then used as a transmitter and a receiver for the communication of image or data. Furthermore, we propose a modified chaos-based image encryption algorithm using the pixel-and bit-level permutations which provides robust, faster and simpler encryption/decryption compared to many other chaos-based cryptosystems. The performances of the new cryptosystem are analyzed and compared with a recently developed scheme [Opt. Las. Eng. 90 (2017) 238-246]. The security analysis and some statistical investigations show that the proposed cryptosystem is resistant to various types of attacks and is efficient for secure communications in nonlinear optical media.

“…Encryption of optical audio or video files and digital images received renewed interests in the processes of information hiding and information security in social networks, communications, Internet such as in the segregation of the design decisions in computer programs that are like to change, thereby protecting other parts of the program from extensive modification if the design decision is changed, privacy protection, mobile or digital phones, tactical military systems to prevent transmitters being located and many more. Both the information hiding techniques and cryptography have received much attention in recent times owing to their rapid developments of digital media and digital right management systems [1][2][3][4][5][6][7][8][9]. There are many different schemes for the encryption of multimedia data like audio signal in which adding noise is one of them.…”

We propose a new audio signal encryption scheme based on the chaotic Hénon map. The scheme mainly comprises two phases: one is the preprocessing stage where the audio signal is transformed into a data by the lifting wavelet scheme and the other in which the transformed data is encrypted by chaotic data set and hyperbolic functions. Furthermore, we use dynamic keys and consider the key space size to be large enough to resist any kind of cryptographic attacks. A statistical investigation is also made to test the security and the efficiency of the proposed scheme.
