Image encryption provides confidentiality to images by transforming them into
unrecognizable forms that resemble white noise. Digital chaos is one of the areas used to …

Developments in technologies, attitudes and investment are transforming the space
environment, achieving greater accessibility for an increasing number of parties. New and …

This paper performs a thorough security analysis of a chaotic image encryption algorithm
based on autoblocking and electrocardiography from the view point of modern cryptography …

In last years, low-dimensional and high-dimensional chaotic systems have been
implemented in cryptography. The efficiency and performance of these nonlinear systems …

Nowadays, the images are transferred through open channels that are subject to potential
attacks, so the exchange of image data requires additional security in many fields, such as …

A novel and robust chaos-based pseudorandom permutation–substitution scheme for image
encryption is proposed. It is a loss-less symmetric block cipher and specifically designed for …

This article suggests a new image encryption algorithm based on a secure variant of Hill
Cipher (HC) and three improved one-dimensional (1D) chaotic maps. The proposed scheme …

This paper proposes a novel method of constructing strong substitution‐boxes (S‐boxes) of
order n (4≤ n≤ 8) based on a recent optimization algorithm known as sine‐cosine …

Fingerprint recognition is a reliable solution in user authentication systems. Nevertheless,
the security and secrecy of the users data are a concern in today's biometric systems and …

These recent years, countless chaos-based image encryption algorithms have been
proposed to meet security needs in real time multimedia communication. However, many of …
