In this article, a novel robust compression-encryption of images based on Set partitioning in Hierarchical Trees (SPIHT) coding-decoding algorithm and synchronization of chaotic maps with non-integer order is proposed. The essential innovation in the

This work presents a new method of encrypting and decrypting speech based on a chaotic key generator. The proposed scheme takes advantage of the best features of chaotic systems. In the proposed method, the input speech signal is converted into an im

In this paper, we present a novel watermarking scheme in the Discrete Wavelet Transform (DWT) domain based on a discrete-time chaotic system. A modified Henon map and a discrete step-by-step observer are, respectively, considered as transmitter and r

In this paper, a secure image transmission scheme based on synchronization of fractional-order discrete-time hyperchaotic systems is proposed. In this scheme, a fractional-order modified-Henon map is considered as a transmitter, the system parameters

The aim of the chapter is twofold. First, a literature review on synchronization methods of fractional-order discrete-time systems is exposed. Second, a secure digital data communication based on synchronization of fractional-order discrete-time chao
