Secure communications by chaotic carrier signal using Lorenz model

Abstract

In this paper, the generation of a chaotic carrier by Lorenz modelis theoretically studied. The encoding techniques has been used ischaos masking of sinusoidal signal (massage), an optical chaoticcommunications system for different receiver configurations isevaluated. It is proved that chaotic carriers allow the successfulencoding and decoding of messages. Focusing on the effect ofchanging the initial conditions of the states of our dynamical systeme.i changing the values (x, y, z, x1, y1, and z1).

A novel technique for encoding images using Chen model and computer-generated holograms

“…One of these works of literature has employed image encryption methods due of its large and complicated data. Using Chaos-based systems, which prevent unauthorized access to data transferred between locations [5][6][7][8][9][10][11][12][13][14][15][16]. Many encryption methods were used in the past, including circular mapping with two keys and an unorganized logistics map [17].…”
