This paper presents a novel framework for generating new chaotic signals for image
encryption that is based on the finite precision of computers. First, we select a system from a …

Over the past few years, chaotic image encryption has gained extensive attention.
Nevertheless, the current studies on chaotic image encryption still possess certain …

In this paper, we propose a novel image encryption scheme based on a chaotic system and
compressed sensing for multiple application scenarios. It is a dedicated scheme for JPEG …

Recently, highly dynamic substitution box (S-box) generators are widely used in
cryptosystems to improve the security against modern computational attacks. However …

Image encryption schemes that use substitution box (S-box) generators, and dynamic S-
boxes in particular, have attracted wide research interest recently. Typically, the security of S …

The quality of encryption is dependent on the complexity of the confusion-diffusion pattern
and the quality of the keystream employed. To enhance complexity and randomness, this …

The constant increase of devices connected to the internet and the development and spread
of technologies such as 5G leads to substantial growth in data-sharing over non-secure …

In recent years, there are numerous studies on chaotic systems with special equilibrium
curves having various shapes such as circle, butterfly, heart and apple. This paper describes …

In the latest research on image compression and encryption, more and more encryption
schemes associate key generation mechanism with plaintext to resist various attacks. This …

In order to address the security risks associated with the theft of private images over open
Internet of Things (IoT), this paper introduces a new Logistic-Sine-Coupling Map (LoSCM) in …
