Nowadays, security in data transfer is of special importance. Images are of the most
attractive kinds of data in the encryption domain. Color images are more attractive than the …

The security concern in recent times has been rising exponentially, this has lead for highly
secured image transmission. Chaos-based image encryption is increasingly used to protect …

The cryptography is one of the important security mechanisms for the confidentiality, integrity
and authentication of text and multimedia data. This study proposes a five-step color images …

Aiming at the security and efficiency of image transmission, a fast image encryption
algorithm based on an improved 6-D chaotic system is proposed. Firstly, we design a hyper …

Confidentiality of images during data communication is a prime concern of many
researchers, as a result, several mechanisms have been proposed for image encryption. An …

This research proposes an encryption method for images based on dual chaos systems and
dual hash functions. SHA-256 and SHA-512 are hash functions chosen to process plain …

The importance of image encryption has considerably increased, especially after the
dramatic evolution of the internet and network communications, due to the simplicity of …

Since images have bigger size than text, a faster encryption algorithm is needed to provide
higher security in digital images. The paper presents a modified AES algorithm that address …

The paper proposes a modification of the Advanced Encryption Standard (AES) to address
its high computational requirement steaming from the complex mathematical operations in …

With the widespread of the Internet and the rapid growth of technologies, several challenges
face data hiding process. Although watermarking is widely used to hide/embed critical data …
