In recent years, a large amount of work on chaos-based cryptosystems have been
published. However, many of the proposed schemes fail to explain or do not possess a …

This paper proposes a new hybrid chaotic map and a different way of using optimization
technique to improve the performance of encryption algorithms. Compared to other chaotic …

Since a substitution box (S-box) is the nonlinearity part of a symmetric key encryption
scheme, it directly determines the performance and security level of the encryption scheme …

Fifth generation (5G) networks are the base communication technology for connecting
objects in the Internet of Things (IoT) environment. 5G is being developed to provide …

In this study, an encryption algorithm that uses chaos based S-BOX is developed for secure
and speed image encryption. First of all, a new chaotic system is developed for creating S …

The expansion of worldwide networking has created new possibilities for management,
development, and presentation in the form of digital data. The uncomplicated accessibility to …

Designing efficient and secure cryptosystems has been a preoccupation for many scientists
and engineers for a long time wherein they use chaotic systems to design new …

In this paper, two efficient cryptosystem schemes in the form of permutation–substitution
based on chaotic systems are proposed. Firstly, a simple and efficient S-box method is …

This paper is to design substitution boxes (S-Boxes) using innovative I-Ching operators
(ICOs) that have evolved from ancient Chinese I-Ching philosophy. These three operators …

Abstract Substitution-boxes (S-boxes) are unique nonlinear elements, which are used to
achieve the property of confusion in modern symmetric ciphers and offer resistance to …
