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 …

Aiming at the deficiencies of existing image compression-encryption algorithms, such as
unstable reconstruction performance and weak crypticity, a novel visually secure image …

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 …

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 …

Traditional image encryption schemes turn images with rich visual contents into
meaningless noise-like ones. This assures privacy security at the expense of visual …

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

Recently, to offer better protection for images, new image encryption (IE) algorithms have
been continuously proposed. However, these algorithms still exhibit some problems, such …

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 …
