Images with sensitive content require encryption for storage and transmission. Symmetric
schemes can cipher them, while an asymmetric cryptosystem can distribute the secret key …

Image encryption protects visual information by transforming images into an
incomprehensible form. Chaotic systems are used to design image ciphers due to properties …

In this world of digital media, security concerns are one of the most pondered tasks upon the
dimension of communication. Now the researchers focus is on developing secure schemes …

Multimedia wireless communications have rapidly developed over the years. Accordingly,
an increasing demand for more secured media transmission is required to protect …

In order to overcome the difficulty of key management in “one time pad” encryption schemes
and also resist the attack of chosen plaintext, a new image encryption algorithm based on …

Aiming at the problems of small key space, low security of encryption structure, and easy to
crack existing image encryption algorithms combining chaotic system and DNA sequence …

At present, globe of modern picture amid the data exchange is more critical. So nowadays,
security issues while data exchange have become the major concern. Consequently …

In the current decade, chaos based image encryption has distinctly captured a remarkable
position in multimedia data security. In this paper, a hybrid chaos based image encryption …

In this paper, a novel algorithm for image encryption based on the hyper-chaotic system is
proposed. In order to generate the initial conditions of the hyper-chaotic system, 256-bit long …

This study presents a novel four-dimensional chaotic system derived from the Lorenz-Haken
equation. The paper investigates the system's dissipative properties, equilibrium point …
