Abstract: This paper presents a novel color image encryption technique using a 5D piecewise chaotic map. In recent years, image encryption has become crucial for securing multimedia data in various ...

A magazine journalist's account of being added to a group chat of U.S. national security officials coordinating plans for airstrikes has raised questions about how highly sensitive information is ...

Abstract: An image encryption technique using modified perturbed map is proposed. The encryption happens in three phases. The parameters of the proposed chaotic map is generated using a random 128-bit ...
