Chaos-based Cryptography for Color Images

Abstract

Data security is one of the most important challenges in the information era; the extended use of big data leads to the necessity of hiding the content of a message from unauthorized users so that, prior to transmission, an encryption has to be performed. Chaotic cryptography, a field of modern cryptology, was recently developed as an application of nonlinear dynamics in the chaotic regime. The paper presents a new approach regarding the implementation of a chaos-based color images encryption algorithm, with a specific application that aims to ensure better information security.
