Over the years, there has been considerable interest in the area of chaos-based encryption
due to the fact that cryptographic algorithms and chaotic maps share a wide-range of similar …

Growing population and limited energy resources have impacted energy consumption.
Limited fossil fuel resources and increased pollution threaten national and human societies …

Transmission of the information in any form requires security. Security protocols used for
communication rely on the use of random numbers. Pseudo-random numbers are required …

Due to the limited machine word length of hardware devices, the dynamics of digital chaotic
systems will degenerate. To combat this issue, we proposed a universal method that is …

Chaotic maps are very important for establishing chaos-based image encryption systems.
This paper introduces a coupling chaotic system based on a certain unit transform, which …

Image watermarking schemes based on singular value decomposition (SVD) have become
popular due to a good trade-off between robustness and imperceptibility. However, the false …

This paper presents a hybrid method for the construction of cryptographically strong bijective
substitution-boxes by utilizing the merits of chaotic map and algebraic groups. The hybrid …

This paper introduces a new image encryption scheme using a mixing technique as a way to
encrypt one or multiple images of different types and sizes. The mixing model follows a …

Image watermarking commonly involves singular value decomposition (SVD) because of its
simplicity and minimal effect on image quality. However, SVD-based image watermarking …

Digital chaotic maps are severely hampered by the finite calculation accuracy of the
hardware device that is used to implement them, and their applications in cryptography and …
