A new meaningful image encryption algorithm based on compressive sensing (CS) and
integer wavelet transformation (IWT) is proposed in this study. First of all, the initial values of …

This research proposes a new image encryption scheme based on Lorenz hyperchaotic
system and Rivest–Shamir–Adleman (RSA) algorithm. Firstly, the initial values of the Lorenz …

The fractional sine series (FRSS) and the fractional cosine series (FRCS) were defined.
Three types of discrete convolution operations for FRCS and FRSS were introduced, along …

In the era of big data, a large number of digital images face the risk of content leakage and
illegal access. Chaos has good randomness, which is suitable for image encryption. To …

This paper proposes an asymmetric encryption scheme for color images by introducing a
new efficient triple-layered encryption scheme based on the RSA cryptosystem along with a …

Achieving privacy over sensitive data is challenging in digital communication. In an effort to
realize this aim, we propose hyperchaotic image encryption through DNA (deoxyribonucleic …

This work develops a novel lossless multiple color image encryption based on multi-layer
permutation-substitution operations. Initially, sixteen RGB images are converted into a single …

With the enormous usage of digital media in almost every sphere from education to
entertainment, the security of sensitive information has been a concern. As images are the …

Image encryption is essential for ensuring data transmission security over open public
networks. Using Multi-Wavelet Transform, Arnold transform, and two chaotic systems, a …
