Confusion and diffusion are two main concepts in cryptography that affect the quality of
encryption and resistance to various attacks. Both of these concepts are influenced by the …

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

Globally, data maintenance and its security are vital tasks due to the rapid development of
advanced technologies. Users now utilise Cloud computing technique and security …

The classical one-dimension chaotic maps are not adequately secure, and some improved
maps usually have a high time complexity. To address these problems, this paper presents a …

Video Encryption is the process of converting the video into an unrecognizable form to
protect it from unauthorized access. This paper proposes a novel video encryption method …

Confusion, diffusion, and encryption keys affect the quality of image encryption. This
research proposes combining bit-and pixel-level permutation and substitution methods …

This paper introduces an enhanced image encryption technique that relies on 3D confusion
and diffusion patterns, aiming to achieve maximum performance in terms of confusion and …

As an effective method for image security protection, image encryption is widely used in data
hiding and content protection. This paper proposes an image encryption algorithm based on …

Classical two-dimensional chaotic systems are not safe enough due to few control
parameters and limited chaotic range. To cope with this problem, a new wide-range 2D …

Pseudorandom number generators (PRNGs) are an essential tool in cryptography; they
produce secret keys to encrypt messages or mask the content by combining it with a random …
